ITS FREEZING here and my heater stopped working. 86 Trans Am TPI. I dont know if its the blower, but i want to check the fuses....where are the fuses for that and what else should i check?? It LEAKS hot air, but does not BLOW the air....can anyone help me really fast, b/c i need to figure this out by tomorrow morning! Thanks.

 

All the fuses are in the same place - in the block under the dash to the left side fo te steering wheel.

Other poosible causes - bad switch or climate control cluster (what you use to turn in the heater/defroster/fan), or even a burned out blower motor....

 

does it blow air if you switch it to ac or vent? you can remove the blower motor and run power to it to see if its dead. listen for a sucking sound around the controls to see if you may have a vacuum leak first.

 

I've tried those and it does not blow air at all...it just "leaks" it....i can feel it, but its not enough to keep the car warm/defog the windows, etc.

 

Ok, i just got in from messing around with it and the fuses. I removed the fuse for the heater/ac, and put it back in. Then i tried moving the contols to vent, defog and ac and it started to blow on the #1-3 settings...but not #4(the highest)....so i dont know whats going on with that setting, but i have 1-3 for the moment. I dont know how long it will last, b/c i remmebred when it stopped working and it started to "sputter"...you could hear it kick in and then stop blowing then start up again and stop.....not sure if this is a motor problem now or what.
