jump power from the battery to the fan directly to see if the fan operates. if not, replace fan. interchange another relay with the fan relay to check the relay. there are usually the exact same relay located in the engine bay.
check fan relay, fuses. jump power to fan. check freon level in a/c system.
Is there power and ground to the fan? If there is replace the fan. If not jump the relay. I would start with the most simple check and that would be the fuse.
Check the 30 amp Blower fuse. If not that check the fan relay, if not that check the blower motor directly from a jump on the fan itself.
take a wire and jump each switch
Jump onto the plug/socket and then jump onto the back of the fan and then jump over the fan blade.
Swap the fan relay with another like relay.
I have a 86 camaro with a 2.8 L . The cooling fan relay on mine is located above the brake master cylinder and is bolted onto the firewall with two 9/32" bolts. There are two relays beside each other and the one for the cooling fan is closest to the fender. If you disconnect the harness from the relay, you can use a wire to jump across the hot terminal to the others one at a time until the fan turns on the check that this is the correct relay for your car.
fan control relay
When you jump across it, you are shorting out the circuit - commonly used for testing components to see that they will turn on. When everything is connected the way it should be, there is also a thermostat which comes into play in the circuit - unless the thermostat gives the "command" for cooling, the fans will not start up.
Yes. Cooling fan, engine fan, and radiator fan relays are all the same thing.
Before you fix the Fan Relay, look for a "RAD FAN" fuse (30 amp - orange). Normally, the computer diagnostic shows the problem is the Fan Relay, but, in my case was the Radiator Fan Fuse ($5). I waste $60 paying for the Fan Relay :-[
