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.
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 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 does my Pontiac Bonneville have low coolant?
Open the cap, when COOL, and look. Low coolant means the heater core gets an air bubble–air doesn’t transfer heat. If it is low, fill. 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.
Can a Pontiac Bonneville have an air conditioner?
The air conditioning works fine but if you turn the temperature up to 80 or 85 so it should be heating it does switch the air from the dash opening to the floor openings but the air is cool not hot.

How does the blower control module in GM 3.8L work?
You can find this tutorial in Spanish here: Cómo Probar El Módulo del Motor del Soplador (3.8L GM) (at: autotecnico-online.com ). The blower control module is a solid state device unlike the old style blower motor resistors that actually use resistors. It controls blower motor speed by varying the voltage it sends to the blower motor.
