Little bit of a backstory.. When I purchased my 87 GT it only had a passenger side headlight motor, which worked. Altought I think my switch is going bad. It only goes MOST of the way up when you hit the button, will go up the rest if you hold the button. Also have to hold the button to get the headlights to lower all the way.

Anyways. I found a motor on E-Bay, and an actuator arm from a fellow member here on PFF.

NOW, when I hold the button to turn them on.... the driver side goes all the way up as it should, but my original driver side only goes up about 3/4 of the way and is not bottoming the lever arm out as it should.

So my question is... when one motor hits its limit does it kill power to both motors?

And also, is there any way to adjust this so both motors should stop at the same position? Even if its not full open. I guess I'm just not understanding why they are opening in such a manner, as they close at the same rate and almost bottom out at the exact same time.

Thanks guys.

I think you have more than one problem. The first one is a bad switch. Take it apart and watch how it works inside, and you can then bend the copper tabs to make contact as they should. After that, your motors may work differently...so problem #2 will be more clear. Usually with Gen 2 headlights, a rebuild is needed with the little clutch rollers.

The headlights are independent of one another and may go up and or down at different speeds. Having taken one of them out, did you get the triangular piece that goes on the motor arm replaced in the wrong position? That can be a cause of the mechanism not making full travel. It's always a good idea to manually run them all the way up and down after removing the motors, before putting the assembly back into the car.

If anything cause binding then module will shut off the motor.

Thanks for the replies. I'm gonna lean towards something maybe binding it up a little and hope I track something down. I had one out since I had to add it to the car new. BUT, the one I had out wasnt the one giving me fits. Its the one that was in the care prior. I'll go dig around and see what I can find. Thanks again guys.

Ok.. I feel like a dumbass now. But the front corner closest to the radiator was catching the overflow hose going to the radiator, therefore causing the load switch to kill the motor. Thanks again.

You could also find binding issues by manually moving the motor knobs and feel for any resistance between full up and full down .
