BodybyFisher Posted July 7, 2018 Report Share Posted July 7, 2018 Have you tested the fans? Try disconnecting the connector and powering the fan directly to see if the fan is the problem.

rockfangd Posted July 8, 2018 Report Share Posted July 8, 2018 I second that. Check the fans. If they test good follow the harness from the bottom of the radiator support and see if it is chaffed or pinched anywhere. Does it instantly trip or as it warms up?

barczy01 Posted July 8, 2018 Report Share Posted July 8, 2018 unplug them individually to isolate the bad fan. Link to comment Share on other sites More sharing options...
