Hello there,
A few things can prevent your fan from working:
- bad relay (you checked that already from what I understand)
- bad fan motor: does your fan come on when your car is idling and you turn on the AC on full blast? If not you could have a bad motor or a problem in the circuit. If it does, your motor as well as your relay, fuse, connector etc are fine.
Also, you can check for a bad motor by unplugging the connector at the motor and connect the fan motor directly to your battery with a set of jumpers. If fan comes on, your motor is good. If not, you either have a bad motor or you have a problem in the circuit.
- problem in the circuit: bad ground, bad/corroded connector, blown fuse, etc Use a wiring diagram and a DVOM to check the circuit.
- bad sensor: on some models the fans are activated by the coolant sensor, on other by a temperature switch. I don't know which one you have, but check in a manual (Haynes, Chilton) and follow their procedure to troubleshoot the sensor that runs the fan.
