Why does my Pontiac Bonneville keep getting cold air?
If you turn the heat all the way up to max (90) and shut the car off and restart it then the heat will work but if you lower the temp till the air conditioning comes back on and then raise it again you get cold air again. Any Ideas ? Thanks I’ve read about this before.
Why is MY 1993 Bonneville not getting heat?
I have a 1993 Bonneville SSE. I was not getting any heat. I sent it to a local garage and they replaced the temp sensor and the programmer. The mechanic said that it wasn’t the problem and is stumped on why there is still no heat control. The mechanic is stumped with the problem and rigged something so now the heat doesn’t shut off.
What to do if your Pontiac Bonneville heater is hot?
Run car until fully hot and speed up motor to 2500 for a few seconds and repeat this 5 times to push water into heater core and get the air bubble out. #2: If radiator full when running motor is hot, are both heater hoses hot even with blower running at full speed.
Are there any problems with the Pontiac Bonneville?
One problem is the blower control module which is like the resistor coils for old blowers is an electronic unit on the auto temperature control models. It sits on top of the air box next to the blower motor under the hood. The relay center needs to be loosened (1 or 2 bolts) and raised to access it. Available at Advanced Auto, etc.

Why is my heater not working in my Pontiac Bonneville?
Most likely it’s the blower motor control module. It’s the equivalent of the resistors that are in manual heater control cars in the old days. It sits on top of the box near the blower motor. You have to loosen the one or two bolts holding the relay center that’s above the heater box there to get it out of the way.

Why does my 98 Bonnevile se never heat up?
98 bonnevile se, changed the battery 2 months ago, 1 month ago heat started to act funny…I can start the car in the morning (letting it idle for like 15 min) and it will blow hot air and heat up, but then when I get in and drive the air goes cold…also if I don’t start the the car and just drive it, it never gets warm…
Where does the vacuum line from the defroster go?
Vacuum lines travel from the vacuum control switch on the dash to vacuum servos under the dash. These servos move the air doors which turn on and off the defroster. If you can hear a hissing sound when the car is running from under the dash then vacuum is escaping.
What causes a car defroster to get stuck?
Heat, extreme cold and vibration of the engine and car’s suspension can cause component of the defroster to fail. In some cases an electrical motor can burn out or the gears inside the actuator can break causing the defroster door to get stuck.

Why is the defrost not working on my GM Truck?
My airflow is stuck in the floor position no matter what setting is switched on the dash vent switch. I can’t get defrost or dash vent air to work. Fan settings do work. Also, there is no light coming on when the AC button and/or the recirculating buttons are pushed.
