I wouldnt let BB put a valve cap on my tire without checking it. I have heard so many stories of major electrical gremlins after a simple radio install from those guys.

 

fordarmyof1, did you ever figure out your problem? I am having the exact same issue. It started last summer and then suddenly stopped doing it. I drove the truck for 11 months and not a single problem... then last week, it started doing it again. I am having the exact same dash light symptoms as you described.

Does anyone have any ideas?

Thanks,

I had similar problems but I noticed it was bad the day of and for a few days after a rain then improved. I pulled the drivers side pillar cover and could see down to where the windshield and body meet and there was about 1/2" of water pooled between the two. My fusebox cought fire a few weeks later. There was not sign of water on the floor only found water if I slapped the fusebox - some was knocked off the wiring I guess.

 

My truck had been sitting at the airport for about a week and it had rained hard several times while parked. I was already thinking that rain has something to do with it... mine is still not working.

 

On my 03 I had a cap installed and they did a real poor job wiring it. My lights were acting funny and almost the same thing as you guys described. Turned out that one of the wires grounded out to the truck. So if i hit a but all would be fine then hit another and things went nuts. I would check all the wires for grounding out on the body or frame of the truck at least any new installs that you or someone else did. Hope this helps. good luck.
