Question about Jeep Grand Cherokee
You are correct in presuming the fan motor is drawing to much current and and causing the relay to burn out problem with this thinking though i would have expected the fuse to go first as this should have a lower ampage rating than the relay and should blow first so if a new motor has been fitted check the fans grounding as if not grouned properley it will cause a resistance hence higher current flow same on the relay itself check the grounding replace the relay with a heavy duty one if you find no problem with the grounding which i think it is i would put an in-line fuse on the live feed on the fan itself as this will blow first and keep the cost of replacing relays or fan again ps check the wiring for signs of overheating yates210456
