COOLING FANS NOT COMING ON HIGH WITH

2004 Hyundai Santa Fe

Air Conditioning problem
2004 Hyundai Santa Fe 4 cyl Front Wheel Drive Automatic 80000 miles

My engine ecm is not giving a gnd signal to cooling fan relays #1 and #2 to turn the fans on high with the a/c. Can you tell me if I can install a used computer without having to bring it to the dealer, would like to try it at least for t/s purposes. Warrantee over on ecm Hyundai telling me I have to bring it to them. Thanks Frank.

A replacement computer needs to be reprogrammed i'm afraid. A dealer will have to do this for you. It could be a faulty engine coolant temp sensor causing the fault. Not giving correct signal to ECM
