Replaces fan switch on outlet side and temperature switch to find out no power is getting to number 1 or correct term main fan relay. Once power is applied to it fans come on at low speed. I didn’t see any breaks in wires when I looked at fuse box wires but don’t know which feed that relay or how to get it power.

There are 4 fuses that run the system that need to be checked for power. This guide can help, and I have included the radiator cooling fan wiring diagrams so you can see which fuses to test and how the system works.

Please run the test with the key on. Check out the images (below). Please let us know what happens.

Everything has power, there’s no break in anything, it’s just for the fan number 1 relay, that’s the only thing not getting power. I need the wiring diagram just for that particular one so I can re wire or bridge it over to it coming on when key is on.

Checking the fan wiring diagrams I don't see one. Sometimes they only use one fan unless the engine is superheated, FYI.

It’s been a pain. I’ve checked everything there is to check can’t find anything wrong with wires or relays, I replaced them anyway and all the switches all, but one that’s in the radiator just no power to number 1 fan relay.
