Question about 1995 Pontiac Bonneville

1 Answer

1995 Pontiac bonneville. When I start my car and let it warm up it blows out cold air when on heat, then if I shut it off and restart it it will then work and blow out hot but then sometimes when driving down the road it will change to cold and i have to do it all over again. Can anyone help me fix this problem?

Hi,
i actually used to have a 1995 pontiac grand am that did the same thing....only difference was i didn't have to restart the car....usually what i would do was drop the car in neutral and gas the car and i'd notice my temp gauge go down and my heater gave heat.....chances are it's a sticky termostat. Hopefully that helped.

I bet you didn't remove your heater hoses where they connect to the engine to check to see if they are clogged with corrosion. This corrosion can also clog up your heater core.

Why wont the heater blow out hot air in my 1995 pontiac bonneville. it will only blow cool air


If the heater hoses are getting hot, the problem may be a faulty blend door under the dash. The blend doors direct air thru the heater core and the vents.

I have a 2000 pontiac grand prix with a digital climate control system. The heat quit working, it doesn't blow out any heat. Now that it is warm outside the air stopped blowing out any air. The digital temperature on the climate control is not correct. When it states that it is below 30 degrees on the ext and it is warm outside the air wont be cold. Once it starts going above 30 degrees the air gets colder. Today the blower stop working all together. Was told it maybe the climate control unit was bad. You can hear the door opening/shutting when you switch the temp from cold to hot. But there was no heat blowing out whatsoever in the winter time. Could you please give me your opinion on whether or not it is the climate control unit or something else?

Have you chg.fuel filter and had a fuel pressure test done? Does it have spark after it stalls? Fuel pumps are a common problem, they work when cold get warmed up they quit, after a while quit all together. Do the fuel pressure test.

Heat blowing Cold when in drive. When in Park, it is warm


have you chg. any thing lately like thermostate? added any coolent to system? if not, thermostate could be stuck in the open position. if stuck open, setting still, it will throw heat, but moving coolent flows to fast and does not get a chance to get hot. if you did chg. thermostate it could have a air pocket in the system. and also adding coolent can create an air pockets too. you will know this when your traveling down the road and temp guage fluctuates up and down. witch means air in system.
