Clicking sound under the hood when engine turns off on 08 Expedition
New to this board folks but I have a problem. I have an 08 Expedition and when drove it back in the driveway I heard a "clicking sound" under the hood. Immeditally I opened it and pulled the #59 fuse which was the PCM relay (per owners manuel). Clicking stopped. I plugged in teh #55 (trailer towing) to see if the original fuse was bad and it started clicking again.
Tells me the "big fuse?" is good. So... what am I missing? Also, when I turned the engine off the clicking started but when I turned it to the aux. position w/o cranking....it stopped.
Any ideas when I need to start???
I appreciate any and all input. I can't afford the dearship rates.
