Which trouble code number are you getting for the fan relay?

Did you inspect the fan relay connector for melted terminals? Inspect the cooling fan connector for burnt or melted terminals. If the fans draw excessive current from binding up blades, that will burn up the cooling fan relay. The relay has to be mounted on a flat surface. The relay is cooled by the frame of the vehicle.





Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
