My radiator fans not working. Replaced all 3 relays, checked fuses. Hooked directly to the battery, both fans work. What next?
Check temperture sending unit.it tells the relays when to cut on.
This self diagnosis question has come up before, I found 2 you tube videos that run you through this with little instruction videos. If I could find them. using google then so can you. I probably searched something like: auto cooling fan repair (or something like that)
P.S.- I tried to put all the steps into words before; but, my explanation got too wordy ; it is easy to stand beside you and point at what I want you to do but harder in just words with no pictures, The videos were both quite complete.
