Honda - Odyssey :: Front Blower Motor Operating Intermittently
Jan 19, 2012
Front Blower Motor does not work. 2005 Honda Odyssey, EX-L130,000 miles and I expect at least 170,000 miles more.
History – Over the past four years, the front blower motor has operated intermittently. I noticed that when the weather went through large changes (warm/humid to cold/dry or vice versa), the fbm would not run. The system behaved in the manner described by Honda owners in many of the forums online. After a period of time passed, the blower would function properly again until the next weather change.
About two months ago, the blower stopped working again and it has not returned to form since. The system again displays all the usual symptoms reported on-line. The rear blower works fine.
The controls on the dash seem to be fine (display changes appropriately as I select settings, vents open and close for heat or A/C or which vents I want open). Air flows through the vents selected when I am driving – I have a passive windshield defroster!
Here are the steps that I have taken during the past week:
1.Bought a new transistor/resistor module, OEM Honda Part #79330-SDG-W41 (I checked with a local dealer for the correct part number). I installed it but there is no change in the system.
2.I found information on-line to test the T/R. I checked the old one – Thermal Cut Out is intact and the resistance between posts 3 & 4 (lower pair when installed) is 1,500 ohms. I checked the new transistor and it read out the same.
3.Fuses, relays, power to the blower, blower, ground beyond the transistor are all fine.
4.I reconnected the T/R and fbm and let the fbm lay on the car floor. I started the car with the fan on. Each time I start the car (or turned the ignition ‘On’) the fbm tries to run, but stops in an instant.
The Rat is cornered – it's in the the T/R and the control signal from the control panel to the T/R corner. If I bypass these elements, the fbm goes on and off as I select the fan On/Off from the control panel.

My mom has a 1988 350 Econoline van chasis that is a motorhome class C.
The front heater/AC blower motor only works when it wants to. It starts very intermittently and then shuts off then you go down the road a little more and it comes back on, it will do the same thing sitting in the driveway just idling. There is no timing it, it just turns on when it wants to and then back off again.
I checked the fuses and the fuses are fine. The blower motor when hooked up directly to the battery blows fine. When it isnt working of course there is no juice going to the blower motor through the hotwire of the blower motor, I have checked this with my volt meter.
I did replace the switch that turns the blower on in the dahs, and it didnt do the trick.

Just had our '04 Odyssey with 162K miles to the Honda dealer to have some maintenance work done. Had cabin filter replaced for first time. Out of the service area, I started the engine fine, turned on heat/a-c, adjusting fan speed to high. There's a pronounced hummer noise coming from under the dash near the blower. It's a constant hum, not something associated with some debris that may have been dislodged or floated down into the blower area. The "pitch" of the hum increases/decreases with the blower fan speed. Service personnel came out, to include the manager, and they exposed the area where the filter was replaced; nothing out of place or loose.
Told me I could schedule another appointment to have them clean out the area inside where the filter and blower are located. Told them that service should be provided as a part of the filter replacement if it could be a concern. Although I'm not a car-savvy person, I'm thinking the problem is due to replacing the cabin filter: new filter, increased air flow (and there is a substantial increase of airflow out of the dash ducts) to the fan blower -- which as been operated with a dirty filter for probably a lot of miles and it has "worn" just right, that the increase in airflow is causing the hum. Fan blower spinning faster causing the hum?

I am trying some troubleshooting based on various things I found for my 2010 Toyota Highlander blower motor. The issue is that my blower motor operates intermittently. Here are the symptoms and what I've done so far:
-Sometimes it works and sometimes it doesn't. It seems to be dependent on weather (in the sun for awhile and doesn't seem to like that), although lately it doesn't really seem to matter. Had it in my garage yesterday and it just works some times and not other.
-If it works, all speeds work (full range). That makes me think it doesn't have to do with the resistors, although I can't find the electrical schematics for the car.
-All fuses are fine
-I have jiggled all wires and can never get it to work (if not working at the time) or to not work (if working at the time), so I don't think loose wires are the issue.
-I put a multimeter across the leads going to the motor and always get voltage. When the car is on, it's about 13-14V, and when it's not running just above 12V.
-The rear blower motor works perfectly, 100% of the time
-Light physical agitation of the motor doesn't make it come on or go off
My main question is what is the 3rd lead going to the motor? The two bigger leads are the voltage, but that seems to always be there, even with the car off. I'm guessing the 3rd lead is some control signal for the motor but not sure. I can't ever get a voltage on that lead, but I'm not sure I'm even supposed to. When the motor was supposed to be on and it was working, I unplugged it and checked the voltages, but got the same readings as when it wasn't working.

We have a 2010 honda Odyssey and we are experiencing some air conditioning problems. The ac went out on us about 6 months ago so we had the compressor replaced. A few weeks after that the ac would intermittently start blowing warm air. We took it back to the shop and they noted that the compressor was shutting off for some reason. They replaced the compressor again, but we are still experiencing the same problem. It will just start blowing warm air for about 15-20 minutes then it will start blowing cold again. This will happen about once every 2-3 days. We replaced the relay, but that didn't work. They have checked for leaks, recharged the compressor and checked the freon and still nothing.

2007 Honda Odyssey with power sliding rear doors. One door (pass side) skips when closing, but only when the van is pointing down hit. Seems to work ok when van is level or pointing uphill. Skipping - the door starts closing, stutters, keeps going, 2-3 times. Usually the door closes, but sometimes it stops and reopens. Is this the motor or some other part/problem?

So for a few months now, my car has been making a subtle clicking noise whenever I have the ac or heat on, kind of similar to the noise spokes on a bike would make when children put a card in them. The noise increases/decreases in speed as I adjust the ac/heater speed.
Recently though, it's gotten to a point where sometimes, the blower motor would completely stop working. I can still feel heat and cold coming through the vents when I turn the AC on, but the it doesn't always blow air. I've noticed that sometimes when I hit a bump in the road, it starts working again. It works at all settings and all temperatures perfectly (when it's working that is).
How should I proceed? I don't know much about cars, but from what I've seen on the internet, it doesn't seem too difficult to replace the blower motor. I just want to be sure that the blower motor is indeed the cause, because I don't want to install a new one to be disappointed when I turn it on and still have the same issue. And winter is just around the corner so I would love to get this taken care of.

My wife has a 06 Sonata with the Manual AC controls. The blower motor works intermittently. Sometimes it works, other times it does not. It does not matter which setting the HVAC is in. Yesterday while driving it, we went over a bump in the road and the motor started running again. Since the motor runs, I want to discount the fuse and relay.

My Blower motor is intermittently going on and off. After messing with it for a while it seems to stay on. Motor may be going out. Not real easy to change the blower motor on this 2008. Haynes manual says to take the 2008 and up trucks to the dealer.

Our 03 Civic recently went into the shop for a rotor replacement and the shop did an oil change for us while they were at it. My wife got the car back and she immediately noticed that the "AC" wasn't working. After asking a few additional questions (I'm not in the same city this week), it isn't the AC that isn't working, the fan/blower isn't turning on at all. We had the same shop check it out again and their response was that they weren't anywhere near the blower motor so this just has to be a coincidence. I could accept that but I'm still worried about a scam.
The car was in the shop just to have the rotors put on, not an oil change but they did an oil change for us anyway. (I was going to change the rotors myself but I couldn't get the caliper hangers off and it was 100+ degrees outside so I decided to have the shop mess with it), Would it be easy to sabotage the blower motor on this car?

2007. Blower motor not working. Replaced 2 fuses for blower motor and relay. Blower motor working. Horrible racket and steam coming from under car when I engaged car. I took the fuses back out. Air conditioner stuck on. I had to take the Compressor fuse out also. Car drives fine just have no heat/air.

I own a 99 Suburban 1500 5.7. The front blower motor stopped working on all speeds so I replaced the resistor, it still did not work. I then replaced the speed selector switch and it started working fine. Three days later I smelled a slight electrical burning smell and the fan stopped working again. I plan on replacing the switch again to see if that is what went bad. Whats causing this to happen? Maybe the motor is going bad and causing the switch to short?

I have a 01 Honda Odyssey and I am getting no heat in the front of the van. In the back I can get heat just fine. Also the front blows on all setting, just cool air. I am wondering, what it might be and what I can check.

Once the car reaches about 80 miles per hour, a buzzing/humming noise is emitted from the front of the car. I can't tell whether it's from the dashboard area or the footwell area, but it sounds like it's coming from below. There seems to be an exact speed where the noise stops and ends. The car does not shake or vibrate when the noise occurs.
The noise has happened twice. Not coincidentally, those were the only two time the car has been above 75 or so miles per hour within the past few weeks. I have looked on some forums for similar happenings, and I found the answer could be bad wheel bearings.
Other problems with the car include a very-vibraty engine between 1000 & 1500 RPM, a gurgling noise at low speeds/idle, and harsh shifting from 2nd to 3rd gear.
I've posted a video on YouTube of the car making the noise. It's a little hard to hear the noise in the video: [URL] .....

Recently bought a 2003 E350. The front heater/ac blower motor isn't working. I found the control switch melted and bought a new switch. Before installing it, I need to do some diagnostics. I checked the blower with a couple of jumpers ant it turns and blows. I think that leaves the blower motor resistor. Where it is on a 2003 E350? I also need to check the relay. I have a power distribution box at the front left under the hood. Is the relay there? The box is not labeled like my GM products. Which is the blower motor relay? Finally, which fuse controls the blower motor? I read it might be a 40 amp fuse. If so, that might narrow it down.

My 1997 XLT 4.0 AWD w/Rear A/C has been having a Blower Motor issue for many months. Occasionally the front blower does not blow. Banging on the Blower Motor, either from under the hood, or even from inside the van underneath the glove box, will start it up again. Once running, it continued running okay until at least the next shutdown. This has gone on throughout the summer. Sometimes a good bump in the road would start it.
Now that the winter is here, heat and defrost are more critical, so it has become a bigger problem. Furthermore, is is now almost constant, where it rarely works without a bang. So it is time to actually fix it now.
From other posts, I think it is either the Blower Motor itself, or the Control Module / Resistor. But since the control module is not located on the motor itself, where I bang, it is probably the motor. Question:
1 - What is the problem, and can I fix it with grease (elbow or actual) etc... or is replacement the proper option?
2 - Should I replace the wheel too, which is not available on RockAuto - but is on the junkyard options on eBay. Unfortunately those are often just as broken as mine. Generic Wheels are available in Auto Zone.

The coolant is leaking from the gasket that is on the front of the engine. My repair guy suggested that I also do the timing belt at the same time. Do I have any other options? The Honda has 217,000 miles on it.

I have had my honda for a few months now and have had a few problems in that time. At first it started with the check engine light coming on when heated up but then my car began to randomly die while I'm driving down the road. Every time that it would die I was able to start it back up almost right after it died. Also when I come to a stop my temperature gauge will start to rise and when I turn the car off I can hear the fans continuing to run for about 10 mins. Now my car will drive until it heats up and then it will die and not start back up until it has cooled down. My dad told me that he thought that my main relay went bad but I replaced that and nothing has changed...

I have a 98 honda civic ex with the d16y8, have replaced the map sensor and iacv and still have a fluctuating idle only when car is warm or at operating temperature. it has dc sports racing headers into a straight pipe then exhaust tip. does not have any o2 seniors on it(wasn't my choice was like that when i got it) will idle up and down between 1700 and 2200 rpm also after replacing iacv the car jerk when going at low speeds or letting off then getting back on accelerator.

The Honda dealership read the check engine light code on my Honda 2002 Accord, that said the catalytic convertor is not operating within the efficiency range(plus the converter has a rattle in it...it is not the heat shield as it was taken off years ago). They said it was too expensive to have fixed at the dealership and to find an independent repair shop to replace the converter.
They warned me to not get the cheap universal converter as the check engine light for the converter would come back on and stay on. They said get a more expensive one but would not give any specific brand or price range and said it SHOULD keep the check engine light from coming about the converter.
I have an independent shop and they agreed about never using an universal converter. However when I press them about the $270 converter they would put on would keep the check engine light for the converter from coming on, they hesitated in assuring me it would not come on.
Honda Accord converter can be replaced with an after market converter, what did it cost, and did it keep the check engine light for the converter from coming on?

My '04 Phaeton was towed Nov. 24 - completely dead, blower motor fan would not turn off...even powered OFF, with key out of the ignition! Both batteries were then drained, had to be replaced to diagnose...
Ended up being blower motor fan resistor. The tech said the ESP/ESC (?) light was "now on" where it was NOT on before all this. He did not run a diagnostics, not sure why. And not sure why service manager didn't mention it before I paid and checked out. :/
But NOW the car is doing some funky things.... upon start-up, whether pulling out in drive or backing out in reverse, the brakes (or SOMETHING ??) seem to be erratically grabbing, there is an awful grinding/scraping noise, the car jerks and stutters and hops, just for a few seconds, then something seems to "give"/"release" and the grinding and scraping and jumping stops and I roll on like normal. BUT the ESP light (that is now CONSTANTLY on), BLINKS/FLASHES when this grinding and stutter-stepping happens. It sounds awful, it feels awful, and it's making me nervous. Of course I contacted VW service immediately, and they're saying I can bring it back in to run diagnostics.
I know for a fact the car was completely dead, NOTHING worked, as both batteries were "fired" according to VW.....so nothing between the car dying and the batteries and blower motor being fixed transpired -- except the towing. And my guess is the had to DRAG it onto the flatbed in PARK b/c it would not take a charge at all to put in NEUTRAL.
