So my 98 cooling fans arent coming on when supposed to, its a 3.8 l. They come on when the a/c is turned on, the scan tool says it gets to about 109celius and thats when i shut the engine off. guage is reading a little above half. I can only get the fans to work when the a/c is on, when i unplug the sensor with key on, the fans dont start runnning. Any help would be much appreciated as i am driving across 3 provinces tommorow !
