I got owned by a gen 1 headlight motor lastnight.

I like to claim that I’m pretty good at diagnosing the system.
I can usually have a problem figured out in about 10 minutes.
But this motor would not go up intermittently. Once you gave the knob just a slight turn it would work fine for several days.

I finally discovered after about 40 minutes working WITH JUST THE MOTOR out of the car. That this cold solder was the problem.

I probably have a few more grey hairs now.

So if you are ever fighting a limit switch problem that just isn’t making any logical sense, see if the wire can be pulled away easily.

Thanks Buddy! I've got a similar issue; I'll check that out!!

i hope it might save you some grey hair, or even from pulling it out
