How does the cooling system work on a Pontiac?
The PCM sends the signal to the BCM, which turns the fans on. Or you can buy a separate temperature fan relay system with a temp probe and bypass the system. It will work as normal cooling when needed only. Its the connecter that you unplug from the temp sensor.
Why are the fans not running in my Pontiac?
your issue is with the temp switch not the temp sensor. the sensor will only operate the fans when it fails to avoid a possible overheating issue ,where as the switch is the fans main controller via ecm. the switch should be on the radiator itself or near the water pump. Hi, thanks for the answer.
Why is my Pontiac Grand Am GT overheating?
Good luck! My 2000 Pontiac Grand Am GT (6 cy/3.4L) has been having cooling issues. I started by replacing the thermostat and performing a flush & fill on the radiator. This didn’t seem to resolve the issue — the engine still overheats when at a stop.
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 are the cooling fans not running on my Pontiac?
The stock engine comes with a plastic intake manifold gasket, which is prone to failure. It leaks coolant into the cylinders and causes inefficiency in the cooling system, leading to low coolant and overheating. You can replace this gasket with a metal one, the repair is a little involved but I managed with a Haynes manual. Good luck!

What to do if your car cooling fans are not running?
Hook your temp sender up to a meter and drop it in some boiling water. This should tell you if it’s working or not. Personally, I’d just disconnect it until you get the issue figured out — running the fans continuously isn’t going to hurt anything, it’ll just be loud.

Why are the cooling fans on my car not running?
The problem persists; the engine will reach 200, the thermostat opens (determined by watching the temp. gauge), but the fans do not start. If I disconnect the (new!) temperature sensor, both fans start.

How does the aux fan control work on a car?
Aux fan control is generally run by a relay, usually tied to whatever engages the compressor clutch (typically the AC switch on your dashboard). I would be willing to bet when the compressor was removed, someone jumpered out the cooling fan relay (s) so both fans run constantly.
Why is my radiator cooling fan not working?
The radiator cooling fans will not come and it causes overheating. It may be the fan relay or switch (whatever it is called). My problem is trying to locate it. Is it near the battery or where is it so I can install the one sold to me by Autozone automotive parts store.
What should I do if my radiator fan is not working?
A blown fuse is no big deal, and changing one does not cost a lot of money. If your car’s radiator fan is non-functional, check your car’s user manual and locate the fuse for the radiator fan controller or the fan. The fan itself often uses a big fuse of around 50A, while there might also be a separate small fuse to the fan control module.

Why does my car overheat when I Turn on the fans?
There was a bigger problem with overheating with this car, even after the fans were running correctly. The stock engine comes with a plastic intake manifold gasket, which is prone to failure. It leaks coolant into the cylinders and causes inefficiency in the cooling system, leading to low coolant and overheating.
