I'm looking for help diagnosing and fixing my radiator fan not kicking on, causing overheating at idle.
I'm only getting 7 volts to the fan plug with the car running and AC on full blast - I blieve I'm supposed to be getting continuous 12v?
I've checked fuse 88 behind the glove box. Looks ok, a little corrosion, 12v+ on both leads.
Not really sure where to go from here, any help is appreciated!

I can not help you with the circut since I do not have the wiring diagram in front of me at the moment, but... Whenever you see corrosion, deal with that first. Remove the fuse clean up the corrosion. Replace wiring and connectors if need.
