I have a 92 bonneville and for some reason the heat works somes times but rarely. If the car is already hot and i turn on the car, the heat starts to work but then within a minute it blows out cold air. Right before cold air comes out, the electronic temp. display flashes. I have replaced the thermostat and am not sure what to do from here. Any help would be appreciated, thank you.


Moved to mechanical 87-91. Please look through our sections for the proper one before posting a thread. It help you get answers when you do so. The "Your Other Ride" section is for posting pictures of non Bonneville cars members own. ~ GXP Venom

Why did you put a topic about a 1992 Bonneville in the 1987-1991 section?

srry this is the first time i used this site. I thought i was posting it right but i must have screwed up.
