Air quit blowing. I push the a/c button and the compressor kicks in the way it should but no air comes from the vents. No problems before. No funny noises, nothing but good hard cold air.


if blower not working at any speed disconnect the blower motor connector and put a test lit across if lit up replace blower motor this cars are well known for melting the connector at blower motor if so replace blower motor and pigtail

Blower fan not working


The resistor bank is bad for slow speeds, the switch is bad for high speed. In your test, you have voltage, but the switch wont carry the amps, to run high speed. Open circuits will not blow fuses. Replace both switch and resistor bank for all speeds. Make sure to clean leaves and trash from fan housing and see if fan spins freely.

How do you change the front blower motor in a 2006 jeep commander? it's gone out twice now since we bought the jeep. the first time we had a mechanic fix it because it was under warranty. but now it's gone...


why not post the symptoms.? (all, not just dead) on all speeds?
the front just unscrews. its not hard, at all. nor worth 500 bucks.
but was that $450 for motor and $50 install? cant guess that ...

did you check all fuses first (in all fuse boxes , not just one)?????
FRONT OR REAR system? wow, with not symptoms i cant guess.
blow dead on HIIGH speed,
is it manual option or climate control HVAC option?
ATC or MTC systems (a means auto, m = manual)
did you replace the blower resistor first, if low speed fails.
did the hot wire test on blower fail, , ? do say this, as wasting a non good blower, is "over the top"

ill guess, front
  1. Disconnect the negative battery cable.
  2. Remove the instrument panel silencer from the passenger side of the instrument panel.
  3. Remove the glove box from the instrument panel.
  4. Disconnect the blower motor wire harness connector from the blower motor power module or resistor, depending on how equipped.
  5. Remove the three screws that secure the blower motor to the HVAC housing.
  6. Remove the blower motor from the HVAC housing.
rear is 16 steps. so..............................

all answers by me are USA cars, (usa forum it is)
and non Diesel, yes, its diffr.

now things that cause (hot wire to blower passes my tests)
failures of blower
  1. blower relay bad,
  2. input to relay wrong.
  3. fuse blown PDC #1 F1.
  4. A/c controller not commanding blow. there are 2 of these. modules.
  5. lots more but i need your unstated facts first. all of them.
all this and more is in the FSM book or at alldata.com diy for $15

order
Fuse 1 good , use a scan tool yet, to see if there are errors>?

Relay PDC relay blower motor front has 12vdc on in 87
ill pretend MTC, system
the 12vdc above goes to the blower, pin 1, is it>?
then the controller grounds pin 2 of blower on high
does it 0v? there? , it does so via ground G200.
if not its bad or the switch to it is bad.
the resistor block does not kill HIGH speed ever. cant. do that.
so is controller, or its switch bad, if not 0v here.
(keep in mind, my hot wire test passes on the blower )O


if 12vdc is at pin 1 on motor
you can jumper pin 2 to ground, fan will blow on
high, if not blower is bad (front)
it if blows now then the controller is bad or inputs wrong to it.
simple huh?

The service light on my 1996 Saturn SL1 came on and right after my A/C completely cut off (no air hot or cold will blow out any more) I checked my fluids added coolant and oil and the service light went...


Air would still blow yes..You should go to an auto parts store(advance, autozone) and ask them if they could run the codes for your check engine light(obd scanner hooks up driver side under hood latch)..Might shed some more light on the issue.. There is a blower motor under your glove box on passenger side. Its likely its either not getting any power or it is burnt up and needs replacement..it has a cover over it.
1.remove cover
2.find where power hooks up and disconnect
3.turn on switch for air to blow
4.test voltage coming though connecter to blower moter(voltometer)
If there is no power coming though connecter, problem would be electrical before blower motor. If blower motor is recieving power but not working it should be replaced.

///////keep in mind. if its a fuse or relay..this could be a huge waste of time..i believe there is a relay for the blower motor. Should be under passenger side kick panel..one of the black labeled cubes. also..blower motor cover is likely to fall apart if your not careful..has a foam insulater inside.

Hi I have a 1998 audi a4 and the blower motor keeps blowing the fuse number 25 once the key is turned on. I know the motor works as I put a hot wire on it, how can i find the short? or fix it with a new...


Hi, first off, check to see if there is anything else on the same circuit, e.g is everything else working with the fuse blown. The cigarette lighter is a favorite. If everything else is ok, use a a multimeter set to amps from the positive battery terminal to the heater motor input terminal (with a suitable fuse in line) to test the amps draw of the motor. You can then compare this with the fuse rating recommended and if it's greater than 2/3 of the fuse rating, then replace the motor. e.g 10 amp fuse 7 amps max loading, 15 amp fuse 10 amp loading.
Hope that helps Matt..

01 grand prix gt blower issues


WEll, the next step is to find where the short is. Disconnect the fan wiring, and replace the fuse again, if it blows, the fault is between the fuse and the fan, but I expect fuse will not blow.

Most likely a fan problem, if the above test does not blow fuse, apply auxillary power to the fan and see if it goes, I expect probably not, but will spark.... if this happens, you would be looking at blower motor replacement.

My heater recently stopped blowing out hot air, stills blows air.


If your blower still blows air just not hot then you are more then likely low on coolant.

The blower motor has nothing to do with the temperaure of the air as long as it blows it is fine the heater core and the coolant level are where you need to look first

best of luck and if there are any more details you can give please do the title gets cutoff and I hope this is what you are asking
