check your fuses/relays.
then try running a pos and neg straight from the battery just to test the fan. if it turns on from thatm then you know the problem is in the wiring.

It will be ok with a toggle switch as a quick fix, but it needs to be fixed right. did you check the relay? ECT sensor?

i did it like a year ago, so im a bit foggy. you just need to find the pinout of the relay, then use a jumper wire between those connections to see if the circuit is working properly.
Or you could go to the junkyard and just grab a bunch of relay's on a 5 finger discount.
and i think you can use an ohmmeter to test the ECT sensor.
