Question about 1992 Pontiac Bonneville

1 Answer

Fan will not blow heat or defrost

The heat does work but the fan will not blow any air around the car and the defrost will not blow. I need to find the fuse box and check that first but I don't know where it is.

Check under the hood where the engine is or maybe on the sides of the dash either side

Defroster fan blows but no hot air comes out


If the heat blows hot, the defrost should also. If the heat does not blow hot air, it could be your thermostat, your heater core valve, or the heater core itself. with the vehicle being a 2002, the heater core is the least likely.

95 Regal blows hot air out the defrost only- no where else!


You have a vacuum problem the car uses the vacuum from the engine to switch the door that makes the air go out the different levels defrost panel and floor it also uses vacuum to move the door which moves to make it pull air through the heating core and the cooling a-coil. Have you messed around on the back of the engine (changing spark plugs, or other work up against the firewall) around the time it stopped changing heat/cooling functions? If so you probably disconnected a vacuum hose if not you may just have a hose that is in need of repair. Also the switch panel that houses the controls can go bad it is an easy fix you can change the whole peice and most of the time it has one big plug in that does it all sometimes it has a plug in for each control fan temp and where the air is discharged

Subaru Loyale 1994 Heating fan quit working


one of two solutions:

The contacts on your fan switch are bad, or you striped the knob and it won't turn the switch on, or the big bad one...your fan motor has decided it needs a vacation.

Hope this helps you, and I hope it's just the knob is stripped..it's the lesor of two evils

Heater blower fan works and blows air perfectly


Look for a loose vacuum hose that should be attached to the damper mechanism for the defroster. You'll have to get way up under the dash to find it with a flash light. The hose may be attached but brittle, in that case a bit of electrical tape wrapped around it may help.
