Question about 1992 Pontiac Bonneville

1 Answer

92 bonneville. The heat suddenly stopped blowing at low or high.

The heat just suddenly stoped blowing. I think the relays are ok but not sure. How do I find out if its the blower motor or the relays. Also is there anything else that could cause this

Why do my heat only blow on low in my 93 bonneville sse


this is usually due to the switch wearing out, replace switch or remove switch and put jumper wire straight from 12 volt supply to the high terminal, if you prefer to have high, switch is typically 12 dollars and easy to replace.

Ac fan stoped working all of sudden the other day I hav checked the fuses and the relays. and when I turn the fan on high I hear a click what do you think the problem is?


Look to see if the ac compressor is turning,look at the center of the pulley on the compressor,if it is turning,it could be a stopped up orifice tube,if it is not turning,check the freon,make sure you have not got a leak.

AC blow out hot at low rpm


when you are stoped does the car idle fine. when the rpms are low the compressor does not get the pressure up high enough. you may need to get you idel turned up a little or your vaccume advance may have a vaccume leak.

Car heat blower is not blowing heat/air into the car


it's either a fuse or it's a bad blower motor, it could be a bad blower motor resistor but usually you'll get either high or low only, so if you have nothing on any speed, high low etc, and all the fuses are ok chances are it's your blower motor.
