Can anyone explain how to bypass the temp relays on the cooling fan and wire it so that it comes on when the ignition is on. The A/C cooling fan turns on when it should but the other fan will not start.I have tested it with a 12V power supply and it works just fine,all fuses are good even swapped relays and it still wont work ? Thanks

 

Why don't you check the fan switch before you rig it up "ghetto style"?

 

Where is the fan switch located thermostat housing , head, radiator ?
