1994 Cobra 5.0, all stock.

Driver's power seat no longer goes vertical nor horizontal. The lumbar and aux plug also conked out.
Since, I haven't adjusted any of these in years, I don't know when it happpened, or if it happened all at once.
Oh yeah, the passenger window doesn't work either.

Checked the 20a fuse, it's good.
I got advice that the cigarette lighter insert might cause the problem. It is missing, and the part you insert it into had some corroded black rubbery piece in it. Don't...
