Re: 1992 Cooling Fans Schematics - Help Diagnose Fans Not Turning ON
Well, if you short the ALDL and it comes on, the relay and fan and wiring are good, so it must be the Coolant Temp Sender "yellow and black wires"...or ECM.
Don't use teflon tape or sealer on the threads, it might not ground properly.
Autozone can scan it for free, and use monitor mode to see real time data to see what your sensor sees.
