I have had many weird electrical problems with my jeep over the years that I've had it, none of them permanent.
I juts recently had an issue with mine.
I was deployed in the Persian Gulf & in the vicinity of the horn of Africa for 5 months.
When I came back the end of July, my driver's side power seat didn't work.
Never had a problem with it previously, so, I just assumed it was an intermittent connection somewhere.
I started digging around underneath that seat and imagine my surprise when I found 6 or 7 different electrical connections!!
I never expected to see that many electrical connections underneath that seat.
Anyway, I took them all part and checked them out, didn't see any obvious corrosion, so blew some of the dust & crap out of them with some compressed air and then reconnected them - I must have jiggled the right wire because it worked - but only for about 3 hours and then it died again.
Determined to try and figure it out, I finally got around to getting the switch itself out and there were 2 more connections behind the plastic panel that the switch was mounted to.
The culprit was the larger of those 2 connections - I disconnected it, blew it out with some compressed air and shifted the wiring going to that connection so it sat in a different position and then put the switch back in and it's been working like a charm since - that's been about 3 weeks now.
That's the only intermittent electrical problem I have had so far - knock wood.
