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.
How to troubleshoot the air conditioning in a Pontiac Bonneville?
If you cannot hear the sound that accompanies turning the air from low to high, then the problem is likely with the blower motor. Change a fuse easily to fix the problem. The interior fuse box in a Pontiac Bonneville is underneath the backseat on the driver’s side. Remove a blown fuse with the fuse remover found inside the fuse panel.
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.
Where is the heater located on a Pontiac Bonneville?
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. It’s held in by a couple of screws and is a circuit board.
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.
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.

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.

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…
Why does my car have a radiator fan?
You probably already know the purpose of the radiator and the cooling system in your car. When you are driving fast, the wind is passing through the radiator to cool the coolant down without issues, but when you are driving slow, there is no wind pushed through the radiator. This is why we use a radiator fan.
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.

How can I tell if my radiator fan is working?
When a radiator fan works it usually makes a whirring sound that is easily noticeable. However, the radiator fan does not always start spinning on ignition. The ECU signals the radiator fan to work at the precise time. So, do not worry if the fan doesn’t immediately start working. Visually check the fan if you don’t hear its noise. 1. Broken Fuse
What happens if your coolant level is low?
If your coolant level is low, there is a chance that you will get air in the system, and the coolant temperature sensor will not read the coolant temperature correctly. If the coolant level is low, you need to refill the coolant to optimum levels. Failing to do so could risk your engine becoming overheated and seized.
What kind of fan does a GM 3.8L V6 use?
Also, since all of the 3.8L V6 equipped vehicles that belong to the GM line (Chevy, Buick, Olds, Pontiac) use an electric fan motor to cool the engine down, I’ve included a simple test to see if the fans are coming on at the appropriate temperature.
