Well, my poor old '98 F-150's electrical system has been possessed by demons.
Lots of weird things were happening: Open the door, and the turn signal relay would click, and the dome light would flash. Electric windows wouldn't work, but when you did press the button, the dome light would come on. Turn signals would work with the headlight off, but turn them on and they wouldn't. And probably the worst of all, the blower motor for the heat/air wouldn't work.
We thought it was the GEM module as that was a common problem with the F-50s and the local Ford dealer replaced it. However still had the same issues. Evidently the cause was someplace in the wiring, and finding it was not going to be easy. It's one of those things that you might fine right away, or it could have takes hours and hours of chasing down. Since I only paid 2K for it 2 years ago, I just didn't think that it was going to be worth fixing.
So I went on an internet search to find it's replacement. I ended up with a 2001 Dodge Dakota 4x4 Club Cab with 122K on the clock.
Not a bad running truck. Does have a bit of rust, but nothing major. Would have preferred a 6-cyl for the better fuel mileage, but this one has the V-8.
Dealer was wanting 4999 plus tax, title, fees, etc. I ended up getting it a 5K out the door. I think it was a pretty good deal after looking at what other 2001 Dakotas 4x4's in the area are going for.
Anyway, here's a pic:
