99 Z28 cooling fans jumper wire
Ok guys, need to perform a quick test here to make sure that my relay hasn't gone bad. Need somebodys help on jumping out the relay for the low and high fan setting so I can test both fans to ensure the motors are still good. Anybody have any diagrams or input on this?
Edit: The low fan setting works. Drivers side kicks on, just need to jump out/bypass the relay to make sure the high setting works.

Thanks man, might end up just pulling the relays and jump the over it just to test the motor functions. There should be a diode inline on the low speed correct? Pretty sure it only pulls 6v or so on the low setting and gives the full 12v on the high setting. Can anybody else verify this?

they arent wired normal. as you can tell. it wires threw one fan to cut voltage on the other fan so it runs at a lower speed. and then that relay turns off bringing 12v to both fans. its a 3 relay setup.

yea what he said looks like they run 1 fan for low and both for high.

Yeah, sorry was looking at a tiny pic lol. Found a larger exploded view of it. That's exactly what happens. Relay 1 opens for low voltage triggered by the pcm and turns on the one fan in a loop. When the high trigger trips, closes the low relay loop, opens the high (12v) leads and runs them parallel at that voltage.
