I did some poking around while locked up in garage due to covid. I did this today.

I’m very curious as I can get my headlamps to open but not to close.

During the summer I gave the lights a try with no response. Moved on to other repairs and maintenance. I had a try again in the fall with power direct to the motor power leads, up and down. I would here a very slight move with moan, figured it was a seized motor. I december I opened the light covers manually after giving the power jump another try. With light covers open I drive for a safety inspection.
Put car aside till this week, since I had time away from regular activities due to our friendly virus. I got out my 73 Imperial body service manual and some tools, jumper wire, test light and multimeter.
I turned on key to run, this is a step I am sure some and I have forgot. Lights are on but no movement, but more noise from motor and relay. Relay is now chippy broken buzz sound like its trying to do something. I went out and took weight off the motor a few times by lightly lifting on doors. Then I did the test as out lined in service manual, first check grounds are good, I did this a few times over the year, the check for power at the connector plug to motor. I had power for on and off. Then it says to check with jumper from battery to the connections after limit switch, doors open and closed. Great, now jump power to connection before limit switch doors opened and closed. Great. Doors were slow and dry squeaking, I opened and lubed all points and after a few cycles on and off the lube worked it's way in and quietened things down.
As you see in video the squeak pops up, put sure will clear with more cycles.
I had pulled TB into shop planning on removing motor for diagnostic dissection. Good thing I went over the tests and checking again.

sounds like you got off lucky ! i wasnt so lucky with my 72 Monaco which sat for 25 yrs, lots of buzzing from the relay even after lubing everything.
this spring i will go through the whole system

Have you opened and closed the doors manually with the knob?
After that try the factory test as I did.
I will try to do a video of steps

and done some hidden headlight front end swaps on cars too
you will get the same issues with a formal 74-78 imp, royal monaco & nyb
