Re: 1967 electric hide0away headlights
I had my system all taken apart about a year or two ago, and as I recall, the arm that connects to the door has a keyed washer on each side. The motor's shaft fits through these washers. A nut ot bolt holds the washers together around the arm with thin flat friction washers between each big washer and the arm. the nut should be loose enough that you can open the doors by hand but still tight enough that the motor can turn the arm without slipping.
I believe the motor has 4 rivets holding the end on. The inside of the motor has teeth that the gears hold on to. The gears are stacked up inside the motor. I took mine apart, and one motor was stripped out, the other one i cleaned out and regreased. I bought stainless screws and I then tapped threads into the motor housing and screwed the motor end back on with these screws and that replaced the rivets I drilled out.
The gears are 4 small gears sitting on a little round plate. there is another set of gears underneath those too. It can be tricky taking it out and putting it back in without it coming apart, but I just used lots of grease to hold it together when I put it back inside the motor. It's kind of hard to explain the gears, but it makes sense once you see them. Checking the gears will require you to completely remove the motor from the headlight housing, which takes a little patience, but can be done.
It sounds like you could first try loosening the nut on the arm of the door that won't open so that you can move it yourself, and also try tightening the nut on the arm of the door that has the running motor so that it will come back firmly against the off switch. I would try that before going to the trouble of removing the motors.
