My radiator fan stopped working. I swapped out my IRCM and it wouldnt turn on still. I checked to see if the fan was getting power by turning on the ac and checking the connection for the fan. There is power going to the low speed. Next I check to see if both speeds work and they do! For some reason I decide to remove the small wire that is grounded from the ground wire on the battery to the body of the car. Normally ive seen the small wire from the negative put together with another small wire but my car has them separated. If I ground both wires the car starts but the fan will not turn on..if I remove the wire that comes from the ground off the battery, the fan turns on as soon as I turn the key but my car wont start! Anyone know what is going on with my fan and the mystery grounded wires?
