On my 73 left headlight it is converted to electric motors. Works the same a vac except it uses the old trams am headlight system. The light assy goes up but stays locked in the up position unless I pull down slightly from the underneath of headlight assy.  This is when it's unhooked from the motor and when hooked up it still won't go down.

I'll throw some guesses out there. If there is enough wire swap the left connector with the right,and see what happens.If that works I would say one side of the headlamp control module is bad. If not try running 12v to the motor and see what happens if that still no, I would suspect a bad spot on the commutator.
   I mounted the module to the front left side of the fender skirt. They are by now probably getting hard to find if you need one. They work on current sensing, so you know how long that will last.  I haven't been following it much but the last I heard they are using the ford focus motors. They claim to be more robust then the GM............jack

Don't think I explained this properly..The motors work fine & are new. The assy will not go down manually or with the motor hooked up unless I pull down on a sensor that is between the 2 large springs. It's like it's locked up & won't release. The motor pulled so hard it actually cracked the bracket that holds the motor & I had to tig weld the alum bracket back together. Didn't notice it until I went to open the hood & it was hitting the broken bracket so had to take it off from underneath...thank god for lifts Smiley

  Wow that took a lot of force to crack that bracket. I wonder if the arm that is attached to the motor got messed up, putting the linkage out of sinc. Those brackets were a pain to make.......jack

Yeah the new motors work great  and have lot of tq.
It goes up fine but you can not pull it down. Instead of taking the whole assy out I'm gonna keep my eyes peeled for a cheap assy I can buy. If I could see it I'm sure I could figure out what wrong. Could be as simple as a bushing gone bad. Not really worried because I never drive it at night & if I ever got caught at nite I can raise it by hand. If you ever get down my way stop in & drive it ..you won't believe  how powerful it has become. It'll smoke the tires in 3rd gear & that's with those wide 17" tires.
