Okay I'm confused. I seached arround to find answers as to why the cooling fans won't come on. The car almost red lines on the temp guage when the car is idling. When I turn on my AC or the Defrost the fans work fine and the temp drops to mid guage. I've tested the fans, relays and fuses and their all okay. I installed a new temp sensor in the water pump and still no fans. When I jump the temp sensor plug with a small wire the fans came on after 5-10 seconds at a cold start. Any solutions? This is driving me crazy.
