My cooling fans will not come on but I wired them direct and they both work does the temp sensor control the relays


Asked by Sep 27, 2014 at 12:21 PM about the 2005 Chevrolet Avalanche

Question type: Maintenance & Repair

Yes and no. There should be a sending unit for the cooling fans as well. Start by checking the fuse. Could be that simple.


All three fuses are good I checked them first was not sure how to check the 3 relays


Swap them with other ones in the fuse box that you know work. Like power window, rear defrost, headlight ect. If the windows , rear defrost and headlights don't work with the swapped relays then you know that the ones for the fans are no good.
