About the headlights not going up and down: I took the mechanism out today. Not easy with radiator still in car, too lazy to remove radiator, spent time inventing tools to use where there was little space. Tested the motor, no action, tested with an ohm-meter, could get 0 ohms when wiggling wires. Hhmm. Checked the price of a new motor, almost $200, so I took it apart, also the gear mechanism, cleaned and greased everything, massaged the coals, reisolated the wires. Now it works.
That's fixing cars at its best:
See problem
Diagnose
Remove
Take apart
Fix
Assemble
Reinstall
Works!
We all know that's not always the way it goes.
One miracle during the fix: I had to remove top front micro switch. 4mm bolts both broke, all the way in, nothing visible. But on the other side, they still pointed 3mm out of the permanently attached nuts. So I thought why not try to get them screwed out that way with a set of pliers. Almost didn't try, the likelihood it would be a success seemed infinitesimal, I was ready to start drilling and welding. But I got both out.
A tip. Adjust the stops in so that when you reinstall the mechanism the motor doesn't try to pull the pods too far in either direction, that could crack paint.
