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.

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.
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.

View 1 RepliesI don't know if its a coincidence but it rained hard all weekend and went to work this morning to find out the blower motor only on 4(high). I checked the plug going into blower motor and it looks dry and clean. is there a common occurrence with this? What to look for?
View 14 RepliesMy 2006 F150 was purchased by me in early 2009 with about 28,000 miles on it. It's an XLT crew cab 4X4 with the 5.4. Stock except for a leveling kit and an aftermarket head unit. It currently has about 59,000 miles and has been babied since I purchased it. About 3 years ago I started noting some issues:
A. Oil pressure dummy gauge is all over the place. Some times it will show no oil pressure. Other times it is all the way to the highest mark. Other times the needle has gone 180 degrees past where normal is and is actualy pointing straight down towards the floor.
B. Recently my alternator dummy gauge has started doing the same thing as my oil pressure gauge.
C. The backlight behind my odometer works intermittently, but mostly not at all.
D. My dome light will flicker when first turned on. It doesn't matter which door is opened or if the override switch it turned on. It takes several seconds to come on and will flicker like there is a poor connection somewhere, but stays on once its on.
E. Blower fan will occasionally stop blowing. Once the climate control switch is turned to off, then back to on it resumes working. This doesn't happen often, but does occasionally.
Fortunately, the truck has not left me stranded and I want to keep it that way. We are getting ready to sale my wife's Toyota and this will become her daily driver. I want to take care of any issues before she starts driving it. Are these all separate issues or is there one common issue which could be causing them all?

View 5 RepliesSo, for a couple of weeks my g/f's Passat has had no heat. The blower fan runs and the AC works but the heat is non-existent. Fast forward to this morning and now all of a sudden her heat miraculously works again. The car has 170k miles on the clock and had the timing belt and water pump done around 120k miles. The thermostat I'm not too sure about. I don't know when (if ever) the system has had a coolant flush so I plan on doing that this weekend. Is it okay to use something other than the G12 VW originally put in it?
At first I thought maybe her heater core was clogged but if it is I don't understand why the heat would start working again. Any tutorial on how to flush this motor properly and how to access the heater core lines so I can try to clear it? On my car it's a piece of cake but her VW stumps me sometimes.
it wont roll up and down but i can pull it up and push it down, however the motor still works but it sounds like sand in the door. is my motor shot or just the regulator, or is it just broke clips?
View 2 RepliesI 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?

View 6 RepliesLooking for info from Bentley manual which relay is for the blower motor, washer fluid pump and 12v outlets? They all went out on my brother's Passat. I'm thinking it must be the relay as we have tested each fuse and they all test fine.
View 1 Replies2000 Chevy Monte Carlo... The heater/blower only works sometimes, usually not at all when it's freezing out. when it's a little warmer out, it tends to work more often, but still not all the time. what could this be? my husband tried replacing the blower motor, but that didn't change the situation, so he put the old one back in, and is now puzzled ?

Blower works intermittently. Sometimes all speeds will work. Sometimes only on high. Sometimes on all speeds but at a slower speed than normal. Sometimes it doesn't work on any speed.
Switch doesn't bind, blower motor doesn't make any unusual noises and I don't think it is the blower resistor. He did notice a strange odor coming from the vents the other day and, it appears that the foam on the blend door is starting to disintegrate.
2005 Dodge Ram 1500 SLT Big Horn, 5.8L V8 Hemi my air conditioning only works when I'm driving forward, and does not work at all any more when I'm sitting still at an idle. this is a new problem. the A/C has worked like a champ for the past year (since I started using this vehicle). I even refilled it by myself last summer, with no issues until now. when it is at idle, I hear a clicking coming from the A/C system, and the RPM's arch a little bit. then it clicks again, and the RPM's go back down. it does this 2-3 times a minute. also when at idle, the air is VERY HOT, considerably warmer than the outside air. also, I have a pressure gauge for the A/C system (came with the refill kit last summer) and it says that the system is holding too much pressure. it suggests a possible mechanical problem.
View 8 RepliesMy 2001 f350 a/c blower works better on a/c compared to max a/c . When I turn the selector to max a/c it makes more of a blowing noise but less air blows out of the vents though. When I select plain a/c it makes less noise but blows more air out of the vents. What is wrong and how to go about fixing it is 93 here today and won't get much cooler over the summer months .
View 5 Replies1999 F250 .. Blower works some times then for no reason stops. When it works, I have all speeds, it makes no odd noises. I shut the engine off and then it does not work. I have power to the blower motor even when it is not working. I doubt it is the speed resistor module because that is not used in high speed. I've taken the blower motor out of its housing and pulled the resistor module as well. I find nothing wrong, power it up and the blower works. I put it all back together and it does not work.
