i have a 2009 f-250 king ranch 4x4 with a 6.4L. i have been having a series of electrical problems with no luck locating a source. Current problems: windshield wipers will not work at any selection, blower motor inside cab for a/c and heat will not come on, headlights in auto mode will turn on and off rapidly during daytime, speedometer will bounce when stopped and while driving at random times, when using keyless entry to unlock truck my side mirrors starting adjusting outward. i have checked fuses, relays, random wire bundles. any suggestions at this point would be greatly appreciated.
Did the body module get wet at all? everything ties into that module, I had a leak in my windshield which lead down to the kick panel and had to have it replaced, dealer only cause it has to be programed for your truck or VIN I should say.
