Ther's nothing to install. Everything is in place and has been working up until recently. Nothing has been taken apart, the rod has not been removed. It's all as I left it after initial restoration a few years ago. It's just that it stopped returning the headlight covers to the closed position after turning off the lights. I really don't think that "centering" the motor is the problem here. It's an electrical problem, not a mechanical mechanical problem. Everything works perfectly when I bypass the existing electrical circuits and power the motor directly with 12 volts. The doors open and the doors close perfectly.

so it operates with the wire way- so I'm thinking that the relay itself has a problem with the close contact inside.

I would think that the problem is in the relay except for the fact that I checked with a VOM meter and verified that when I turn on the headlights the Blu/Yel wire becomes energized while the Red/Blk is not. When I turn off the headlights the Blu/Yel wire is deengerized and the Red/Blk is energized. Seems to be working correctly?

not to get nasty here- but connect it all back together and recheck both wires.
reason is that without a load on it- the meter will it ok

but with something connected and showing almost nothing would point to the relay's conact being bad- try it and let us know!!!

You're not being nasty. You're helping and I appreciate it. I didn't think of the "no load" possibility. I'll try it again all hooked up. Also, there is always the remote possibility that the problem is as simple as a non connection within the connector itself. At any rate, I'll hook it back up and keep you posted.
Thanks

Agree with 71 Deputy, may be a load issue.
I think I had that issue as well at some point.

Listen for the "click" of the relay.

You can also take the cover off the relay ( carefully) and check the contacts in there.

I think I did that as well.

Interesting. It'll be difficult to rear the relay because it's located under the dash but I'll try it. Maybe it's a simple thing like dirty contacts on the relay.....or just simply that the connector pins to the motor isn't mating well.

its just the contacts inside the motor itself.... dan

You should be able to remove the relay easily enough. I think mine was attached with 1 nut/bolt.

I agree that it sounds like a contact issue, whether it is relay or motor, as the car was sitting for a while, and worked fine beforehand.

I used a Chevy truck accessory relay in place of the factory on a 70 dodge charger.

More info saved from the web.
Sorry for not remembering who.

I made that diagram long time ago

need to mention the advantage to hook on RUN circuit like is originally instead ACC like I suggested there, is to be able to keep the doors open when turn on lights, key in off, and then turn off the lighst without close the doors, for service or washing purpouse

if it's the motor contacts then why would the motor work perfectly opening and closing when going directly from the battery and bypassing the relay?

Makes sense.
Did you check the relay contacts?

Well, I think I found at least part of the problem: One of the connections in the rubber connector coming from the motor (the one that closes the headlight door) was rusty and wasn't making a good connection. I cleaned it out with a dremmel and the headlight doors now close as well as open. Such a silly little thing causing such a huge investment in time and energy. Welcome to the wonderful world of 40 year old Mopars I guess. Thanks guys for all your help!attaboy

Not to be a d**k here, but that is always the first thing to check. Always clean the connections first.

Glad to hear you found the problem !

Figured it had to be a connection thing, as you mentioned the car was sitting for a while.
