my car was rigged with a seperate switch for the right side headlight motor it would go down with switch but not come back up except manualy.i found a motor in junk yard and hooked up the motor to the relay and no extra switch.this motor would run and not cut off when switch was off and stop when switch was on [headlight switch that is] i tried switching the relays and even jumped the relay from left side to right and it still didnt work right i think its a motor problem but not sure, need expert help before i start to spend money.oh by the way its an 84. thanks Rod

I think that some pictures of your setup might help. When you say it would "run" when the headlight switch was in the off position did you have the headlight installed? It will run continuously if it is not mounted in the headlight assembly to stop the motor. When mounted properly it will hit the limit and stop, same goes for going into the down position. Does it stop, spin, click? This will help us diagnose more clearly. Have you checked the electrical coming from both the headlight "up" wire and the headlight "down" wire? My father has my voltmeter, but if I remmeber right you should have 12v coming from both- power on the close when the lights are off, and power on the "on" when the lights are on. Might be a good place to start. This will help you know about the relay. Pics might help too if your wiring is all different from the manual switch you mentioned.

like NextFiero asked
Was the motor actually attached to the headlight assembly?
The motors will run continuously because the limit switch isn’t being tripped

do you have a test light?
and some wires to use as jumpers?

funny.
what's worse, is i had no idea the hair on the back of my head was thinning until i saw myself on my videos last night.

holy sheet!!!
i'm loosing my hair.

anyway...
I’m kinda expecting 2 different problems.
I understand that you wont be able to do any of this until tomorrow.
I’m going give you some directions, and ask yes or no questions.

Don’t skip any steps and answer all of the questions and we can get this wrapped up pretty quick.

With the motor attached to the headlight assembly.
Start in the down position.
Unplug the pigtail from the relay and the single blue wire
Use jumper wires and apply
Power to the green wire
Ground to the gray wire
Does the headlight come up?
Does the knob stop spinning once the headlight is up?
Watch the knob for about 60 seconds, does the knob twitch?

With the headlight in the up position
Unplug the pigtail from the relay and the single blue wire
Use jumper wires and apply
Power to the blue wire
Ground to the green wire.
Does the headlight go down?
Does the knob stop spinning once the headlight is down?
Watch the knob for about 60 seconds, does the knob twitch?

Now let’s see if there are any problems with the system on the car.
Use a test light if possible, a multimeter can read voltage, but may give false results because a circuit may not be able to carry the amps.

Unplug the 3 wire pigtail from the headlight relay
Unplug the single blue wire from the motor.
With the headlight switch off.
Does the red wire have power?
Does the blue wire have power? (not the one going to the motor)
Do you have a good ground at the black wire?

Unplug the 3 wire pigtail from the headlight relay
Unplug the single blue wire from the motor.
With the headlight switch on.
Does the pink wire have power?
Do you have a good ground at the black wire?

buddy i tested the motor and it runs all the time in the up and down position it will take the motor up and down ok it seems.i tested the limit switch you know pulling up and down on the knob and i could hear the tick .I have not been able to find my test light and may never [22 and 20 year old boys] find it so its going to be a little while till i can test relays.but ill be waiting for you to tell me to rebuild motors. ps i am a little thin on the top too,dont know if i wore it off or the 22 @20 yr olds have done it to me thanks again Rod

if by that you mean the knob keeps spinning, then yes the plastic gear is stripped.
i was going to say that it's odd that the gear is stripped in 2 places. the up stop point and down stop point are about 45º away from each other.
but if the green bumpers are destroyed then the gear will rotate on the shaft probably about that far. so most likely you only have one bad spot.

since you dont have a test light, i guess rebuild the motor and we'll worry about the posibility of other problems later.

i wont tell you to use JB weld with rodney's gears, i will say that if you bought a motor from me, that's how it would come.
