Blowing out of the defrost is a vacuum problem. You have a leak between the motor and the heater controls. Most likely needs to have the A/C system charged up.

Heater fan in 1991 Pontiac sunbird stopped working. We have replaced fuses, and the fan motor. Still not working, continues to blow the fuses. What to do?


Replace the blower motor resistor assembly. To locate the electrical connector for the blower motor resister, it is usually attached to a heating or air conditioning Duct, or the blower motor case. You can also trace the Purple Wire from the blower motor back to the resister. Also make sure that the blower fan is not jamed up with somthing in side and will spin freely,or binding same thing, this will also cause the fuse to blow right away. And does the motor actually spin a bit before it blows the fuse or does it blow the fuse at the same time the switch is turned on? Good Luck and have a good XMASS.

I have a 1999 Chevy Suburban. It has a dual air conditioning system. Everything works fine,except the front high switch, making it a slow cooling process in 90 degree,bumper to bumper, weather. Does just...


Sounds like the blower motor resistor. It should be mounted close to the blower motor. The blower motor resistor may run around $50.00, you may need to replace the plug, dealer item, around $60-70. Shouldn't be $1000.

91 ciera only does defrost, no vents or AC


i believe this is a vacuum operated system. if there is a problem with the vacuum supply to the control unit, it will automatically default to defrost. i would start by checking the vacuum source lines. good luck!

Front air condition does not blow cold. Rear air condition does


sounds like a damper door in the front not working properly, these are actuated by the front temp control, the door is operated by either a manual cable, and electric actuator, or vacuum. I hope this helps you zero in on your problem. Merry Christmas

Air conditioning


Yes! You are absolutely right, sometimes when you drive on rough roads, the lines from the condenser(cold air module) may get loose and you lose your cold air. The fact that it's blowing in one part of the vehicle and not the other is a testament to that. The best advice is to get the air conditioning checked out. they do this really neat thing where they pressurize the line to find out where the leak is coming from. Hope this helped.
