Sorry - which ones? A/C heating or engine cooling fans?

Check fuses to make sure they're still ok. Remove the ones for the fans - and replace to clear any corrosion off them.

If it's the cooling fans at the front, these are controlled by a temperature switch which may be faulty.
Locate it , and measure the conductivity between contacts when cold - and when engine is very hot. The switch should close at around 90 degrees - 3/4 of the temperature gauge.

If the switch is ok, the relays controlling the fans are probably corroded.
Sometimes mounted on the fan housing - follow the fan motor wiring directly to them.

Hope this helps.

Engine temperature switch tells the fans when the engine reaches a temperature in which the fans should operate. Change this and you will more than likely solve the problem.

2004 Pontiac Grand AM Cooling motors wont work.

Can you jumper the relay to make the fans run ? The computer sends a ground to the relay to power the fans when the coolant temp reaches 220 degrees or when the ac pressure reaches 200 psi on the high side.

My 2004 pontiac grand am cooling fan doesn't work what do i need to do

The cooling fan can be run through a self diagnostic by a dealer using a special tool called a scanner, it will then deliver back to the tech what is found, this can be any number of things, the fan motor wiring to it or the controller for the fan. Guessing is not an option and if you keep overheating this engine you will shortly need a new one.
