one of the cooling fans is controlled by the coolant temperature sensor, and the other cooling fan comes on when the a/c is switched on. they may run simultaneously if conditions are correct.
One of the fans is elec. controlled and only comes on when temp. gets high enough. As for the lights for abs and srs, they could be from one bad sensor, not sure but abs is anti-lock brake sensor and srs could be a speed sensor and both are mounted on wheel so could be both on one sensor. Hope that makes sense. No pun intended.
Check the fuse, thermal relay, and wiring. If all that is good then the fan motor may be defective. Apply 12 volts DC directly to the fan motor to verify it's condition.
The cooling fans on a 2002 Grand Am GT might not be working because of a problem with a fuse. There is also a temperature sensor in the engine that tells the fans when to come on. This sensor may be bad.
no they cant
My cooling fans not working on my 2001 Santa fe . By pass fans they work, put on new heat relay still not working
Check the relay.
If cooling fans stop working and engine runs hot wtih A/C on usually excessive head pressure will build in a/c compressor and refrigerant will discharge from system. cooling fans may have a bad fuse or relay should be repaired prior to recharging a/c
Cooling fans are controlled by the computer based on input from temperature sensor. After the vehicle is shut down, if the temperature is still high, the computer will turn on the fans to cool the engine.
code 35 has to do with the cooling fans not working properly
In all probability it is the cooling fan switch. Before you replace it you need to check the fuses. The cooling fan switch is on the intake manifold.
The engine temperature must reach 232-235 degrees in order for the cooling fans to come on. They will shut off at about 195-200 degrees. Also when the air conditioner is on the cooling fans automatically come on regardless of temperature.
The cooling fans are the only cooling source for a air cooled engine.
failed coolant temp sender for the fans
the thermostat will make both fans become idle if it is not opening. this happened to me on my 95 3.1 lumina
