Hey, I'm trying to make it so I can turn both my fans on with a switch. My passenger side temp sensor/switch broke, so I figure I can just wire the black wire from there into a switch and use that to turn the passenger side fan on. But I'm not sure how to get the driver's side fan to come on. I looked for a green/white wire near the firewall on the driver's side but don't see one.

Where is the wire I need to splice into to get the driver's side fan to turn on?

Also, is the driver's side fan the one that turns on with the AC or the passenger side?

Thanks
Mike

 

the primary fan(drivers) is controlled by a temperature sensor in the block, the aux fan(passenger) is controlled by the AC condenser pressure i believe, when the AC is turned on so is the aux fan, and whenever the aux fan is turned on, the primary fan is turned on

If u follow the wires from the fans, u should be able to locate the relays

 

i am just using the stock turn on temp for the primary fan, and then manual switch for the passengers side fan, so i can turn it on and off when the car is on.
