1G radiator fan won't turn on

[scheides]

Having radiator fan troubles on the 1G. Checked the fan, it spins if I wire 12v to it, no problemo. This is the stock fan on the passenger side, wired into the stock plug. What is it that makes this fan spin when the car gets hot, is it the ecu, triggered by the lower temp sensor? Sensor feeding the gauge seems to work just dandy, have not hooked up a logger to verify the other sensor is working. I have not tested the voltage at the plug, either. Just wondering if anyone has any suggestions to get this thing spinning!

hey, im not positive but isnt the right side wired in for the a/c switch? I thought it was the secondary but maybe im wrong.


edit *Passenger side*

Side question, anyone know a good place to just hardwire the fan on when ignition is on?

He is talking about the fan on the passenger side of the car which is the main cooling fan.

^ Thats what im talking about, thats where mine was wired and it only worked with the A/C switch on...

Maybe i am nuts, but I think the A/C fan is on the driver's side...its been too long!

A/C fan was wired on the driver's side as far as I know.

Swapped the relays and checked the fuses, still no go. I'm wondering if the pass side one *is* the a/c one. I'll try that tomorrow.

Should turn on at about 203-206F
