Phaeton :: Blower Motor Fan Won't Turn Off
Feb 6, 2016
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.

I have a problem that's sprung up all of a sudden and I wanted to run it by you before taking it in to VW. For the past three days or so the blower on my Phaeton's HVAC has been unresponsive to my control, staying on its highest setting permanently, even when I turn off the car.
This of course means that overnight power management takes over and when I get to the car in the morning I have to unlock it with the physical key, the clock has to be reset and I get all kinds of warnings about level fault and system fault. These warnings go away immediately as the car powers up, and everything is back to normal except for the fan.
I've tried resetting all settings on the control unit, but since the fan stays on even when the car is off, I feel like it's not software? The rest of the HVAC settings seem to work fine- I can toggle the vents and change the temperature, just not the blower speed.

It started with the blower motor that wouldn't turn off by itself when the truck was turned off. I forgot to turn the fan off one night and woke up to a dead battery. Got my dad to come give me a boost and it would turn but not start and the anti theft light in the dash was blinking fast.
Later in the day I got another boost and it started right up.
This was yesterday... after the last boost and startup I went and got a few things, stopped to get gas... started back up fine each time.
Last night I was greasing zerks and making sure everything in the front end was nice and tight when the abs module started clicking... and the anti theft started blinking and truck wouldn't start. Left it alone and went to bed.
This morning I boosted it and it started fine. Later in the day it wouldn't start again because of the anti theft. Gave it 5 minutes and it started. Stopped to get gas... wouldn't start (anti theft)... started after about 5 minutes.
On the way back home... it's been making this 5 beep, pause, 5 beeps, pause sequence so I pulled it into the garage and turned it off now the locks are locking/unlocking by themselves randomly, the beeping is on and off, anti theft light blinks for a few minutes then goes away only to come back...
I've been told to remove the fuse box under the hood and check to make sure all connections are clean... I've searched and seen possible solutions ranging from a dirty connection to needing a new GEM module and apparently sometimes just a low voltage situation will cause our trucks to act nuts...

I have a 2001 GMC Jimmy and I am having an issue with the blower motor. Speeds 1 and 2 do not seem to work. Speeds 3 and 4 work fine. This is the manual climate control not the automatic. I searched and it seems everyone usually has a problem with the high speeds & not the low speeds...

My wife heard a humming noise on a 200 mile trip to Long Island last week. It was loud enough that she was concerned about it and took it into a Toyota dealership to have it checked out. Of course, the noise went away, and they assured her that the car was perfect!
When she came home, I drove the car and the noise came back. Radio was off and the frequency of the noise changed with the AC/heater blower speed. Turn blower (fan) off, and the noise completely disappears. Before I got home, noise disappeared again with the fan on. I believe it is a bad bearing in the blower motor.

I'm getting this weird chirping noise from what sounds like the A/C and Heat fan. When I turn it down it is noticeable and sounds like something needs oiled. Kind of like pieces of plastic hitting each other over and over again. When I turn the air up there's no noise but probably because the air rushing out is so loud. I'm thinking I may need to take something out and oil it up. Too cold here to do my own thorough investigation.

My prius that I got about 1 1/2 years ago (2013 model) was making some noise. After conducting a few experiments I came to the conclusion it was the heat that was causing it. I removed the glovebox and lower plastic panel as well to see if it was actually the blower that was making the noise. And it was the blower.
So now it's like 20 degrees outside and I haven't used the heat because I didn't want to blow something so gotta get this fixed ASAP.
Like I mentioned glovebox and lower panel are open I've removed 2 of the 3 screws necessary to remove the blower. So the problem lies with the 3rd screw. There is a plastic socket with wires that is preventing me from reaching the 3rd screw so I have to remove that socket. So I have a couple pictures and how I can remove this so I can access the blower motor.
Also isn't it strange that the car isn't even 3 years old and the blower is giving me problems?

How to replace blower motor in 01 Prius. There are no way to get from to it from under the glove box.
Blower motor was working fine. I decided to remove cabin filter. Filter had not been changed for very long time. There was a lot of dirt, pine straw and leaves on top of the filter. When I removed the filter a lot of dirt fell inside the motor. Ever since then motor is working on and off. Often have to hit under the glove box and it works again for a while. Tried to remove the blower but could not get to it.

Several weeks ago, the blower motor in my 2010 stopped blowing. It came on within a day or so, but failed again, so I replaced it with a new part from Rock Auto: TYC 700249.
The new fan just stopped again. I plugged the harness in and out several times and it did briefly come on a few times, but clearly something else is going on.
I don't know if it's relevant, but after I took out the OEM fan, I experimented by removing the plate from its back that has wires and capacitors (actually, I don't know what I'm talking about) and connected the main prongs directly to a 12V battery. It came on right away. I installed the new fan anyway, figuring it was the plate/wires assembly portion that was bad. The "resistor?"

I recently got another blower motor for my vibe. Got it installed but nothing happened. I replaced the resistor as well. Once I found the secret hidden fuse panel I found that the 40a fuse was blown. I replaced it and it blew instantly upon turning the ignition on, the resistor was unplugged at the time. I am wondering if there could be a short in the wire harness.
The blower went bad a while ago and blew a resistor, I replaced it and it ran for a while until some smoke came out of the dash and then nothing.

So my AC only works on 4 (no 1, 2, 3). I replaced the resistor as is often the culprit. NOTHING. Still only works on 4. So I unplugged the resistor all together, still only works on 4. So, either my new replacement resistor is also bad (unlikely), or it's the blower motor.

My girlfriend has a 2005 accent and recently the blower motor started working intermittently.. After a couple of days of it coming on and off it now wont come on at all.. After checking the 30amp fuse under the hood, and the relay they all seemed to be in good shape, I even swapped them out with other fuses and relays to make sure that wasn't the problem. I checked for power at the Motor and it has 12 volts going to it when the fan switch is on.. so I pulled the blower motor itself and connected it directly to a 12 volt source and it worked, eliminating the possibility of the motor itself being seized. Now I read up on a few sites on how to check the resistor, so I did a few continuity tests on the resistor itself and didn't see anything out of the normal.. What I should check next or what the actual values on the resistor check I should be reading..

12 Santa Fe, I decided I better give it the once over. I found the cabin air filter was pretty bad and that surprised me because I don't drive in dusty areas etc and usually don't drive much at all any more since I got a company car but anyway....to the question: AFTER I changed the filter, making sure the airflow arrow was correct, I noticed that the blower motor is much noisier than before especially when set on the higher fan speeds. The sound is much like a off balance fan with a bit of a thump to it. Could I have dropped some of the dead bugs into the fan when I changed the filter? I was careful and didn't see anything fall into the fan area but the noise is annoying as heck. Is this something that would be covered under Hyundai's warranty? Headed to the Florida Keys Saturday and not looking forward to hearing that racket all the way down there.

Today i had my ac running and switched the speed from 3 down to 1, then poof totally went off and will not come back on at all. I tried replacing the resistor, still nothing. Next tried the blower motor, still nothing. Then replaced all the fuses, still nothing. The compressor is kicking on. Can here the click under the passengers side when turning ac on, but the blower motor is not coming on.

I have a strange whistling sound coming from the blower motor inside the cabin. Sometimes it stops when I accelerate and sometimes it stops when I come to a complete stop. It's very strange. The heat seems to work just fine and I have no VAG COM errors. What this could be or how to fix it?

I have an '02 F150 XL. 200k miles. My a/c blows cold, and I have every fan speed, but it just doesn't blow very hard. I replaced the blower motor thinking that would work, but that did nothing. I've been told to clean the evaporator core, but I don't know where that is. How to do that, as well as any other part causing the problem.

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.

I have a 1989 towncar. The blower motor works in any selection (vent, panel, hi-low, mix, defrost) but does not work in the "floor" position. It also turns off in the off position as it should.
I changed out the entire climate control assembly with another one from a junkyard. I thought the function selector electrical switch might be bad. However, the blower motor still does not work.

2000 Alero. Wife reported to me she had no blower motor. I pulled the motor and it tested good. Next I replaced the resistor with one from auto zone. Now I have blower in all but the 5th and highest position. I suspect a bad new resistor but I left it for now because it's a pain to remove.
Could I have got a bad resistor? In my experience a bad resistor will give you high and nothing else.

My a/c has not been working so we added R134a yesterday and it fixed the problem just like it did last summer. Once I was finished I left the a/c on high when I shut my car off. This morning when I left for work it was too cold so I turned it to the "off" position. On my drive I decided to turn the a/c on and make sure it was still getting cold at which point nothing happened, absolutely no air (hot or cold) was blowing out. I kept turning it on and off and at one point the a/c did start working again at which point I turned the fan speed to low. A few minutes later the blower completely quit working again. Nothing works at any speed, any position regardless of heat or a/c. Absolutely nothing is blowing out of my vents. I can hear something that sounds like opening and closing when I change the position/type of a/c/heat but the other than that the only sound is a "shhhhhhh" when I turn it to the off position. Where to start on diagnosing and fixing this issue?
