Hello guys, i have a 98 Jeep Grand Cherokee 120k miles, and its got a 5.9 Liter v8 engine. It has a electric 2 speed fan on it.
I was told the electric fan has to come on when the airconditioner turns on, yet mine does not come on at all. It only turns on low speed when my engine reaches 200f. I jumped the high and low speed fan switch on the radiator hoses to make sure the high and low speed motor was still working and it is. The relays both clicked on when i did it so it isnt the fan or the relays i dont think.
I know this vehicle has a AC pressure switch and I was told when you turn the AC on the pressure switch grounds the wire and turns the fan on. If this is the case then my pressure switch is probably bad ? How would i go about checking this ?
