64 corvette I have replaced the motors on both units but the passenger side one has been doing this. It works two or three times, then stops.
I then have to loosen the manual thumb screw to get to come up again.
and it works for another 2 to 3 times. anyone have any thoughts on problem?
Thanks

Hi batman,
Are the motors new or old replacement motors? Has the grease been replaced? If not, the old grease gets very thick over the years and creates the problem you are describing. The problem can also be an electrical contact issue as Jim mentioned, but look into the grease first. Been there... done that!

Batman,
I assume you didn't have this issue before you replaced the motor. If that's correct, then I would clean the electrical contact and make sure it and the ground are tight. If the issue persists, then I would think it's an internal issue with the motor and would ask the vendor to replace it under warranty. Let us know how it goes.
Did the buckets move freely when the motors were not on/attached?
If not, check the outboard headlight pivot shaft, it is not easy to get too....you might have to loosen the collar to adjust it so the buckets move without binding...
I don't know of anybody making "new" original-style motors; unless you got NOS motors.
If they are rebuilt then somebody may have tried "flipping" the main gear 180* instead of replacing it. That works about 3 out of 5 times. If its galled enough it'll eventually hit an ugly spot and affect operation... Or they may have mis-adjusted the preload.
got it from Corvette Central said it was new so assuming not rebuilt. seems strange that it works a few times perfectly then seems to lock up , but when I turn the manual raise/lower screw it works again
That really sounds like a preload or gear problem....assuming the buckets aren't binding. With the motors out you should be able to 'flip' either headlight bucket up/down with a slight push of a finger. You can bench test the motors while they are out.
Checking the connectors forward of the hood for corrosion/looseness is a good idea too.
Gear inside the motor is jamming. Are the the Chinese motors??
There's your answer if turning the wheel is needed to unlock the motor, and yes they do make Chinese versions of these motors which are not very good from what I hear.
If Corvette Central will take them back and credit your account....
I would purchase these if you not looking for NCRS correct, but want something that works when you want them too...
.
I have them as do a lot of others here on the Forum and they work flawlessly cost less than Originals....
I had mine do that as described in post 8 & 12. They worked well till I installed the motors I rebuilt. Put new gears in the motors along with brushes and turning the com. The motors tested great and the buckets moved freely til I put the motors on. one worked good and the other was slow.
I found the slow one rubbing the body after I adjusted the bucket to center. If I move it to one side it worked fine. I removed the bucket and sanded the area it was rubbing, repainted and all was fine.
Just a thought, if the ground screw in that motor is just a tad too long, it can touch the field winding, short out, and cause a inop condition.
I had a intermittent once and the screw was too long in one of my '63 motors. Drove me crazy until I realized the screw was intermittently shorting out inside.
Pull the ground screw and check it's length, and make sure you have a external toothed washer between the case and the ground lug. Also no paint on the case under the washer.

The ground screws are very short....
I read about that somewhere -- worth checking out..
