Hi I hope you can help. The fans keep running after I turn off A.C. Even when engine is cold. They sometimes run up to ten min. After it's turned off. Relay on left top bumper replaced new, pressure switch new. Dealer replaced fuse box and the little computer mouted on front of fuse box. Nothing has canged anything. Any Idea What's Wrong?

The water temp. Is working ok. I can let run till temp. Comes up and starts fans with A.C. Off they will run till temp. Goes down they will cycle on and off. If you turn on A.C. Till they come on then turn off A.C. They stay running for about 5 to 10 min. Even when engine cold.

Hi:
I want you to try something. Remove the relay and see of the fans keep running. If they do, there must be a short. If I recall correctly, the relay is the last place the power goes before the fans. By removing the relay, the fans should stop unless there is a short. Follow the wires from the fans to the wiring harness. Where the harness leads should be the location of the relay.

Let me know what happens.
