Default Headlight Alignment _1986

Does anyone have a good procedure for aligning the motor on the 86 so that the lights rotate to the correct position?

Take the screws on the inside. If you want to go up, turn it to the right. If you want to go down. Turn it to the left. Thats how it was on my 90. But I have not done it on my 86. The inspection shop did. Do it alighing on a wall like in your garage or something. Make it easier. Please someone correct me if I am wrong. But the screws in there do move it up and down. Have your inspection place do it if you dont want to or dont feel comfortable doing it. They do it for free.

Default A wasn't clear with my Question

The motor on one side does not move the assembly to the full up or full down position correctly.

How do I align the assembly to the motor or visa versa, such that when the light switch is turned on it goes to the correct alignment on the car. Door or fully flipped up?

I just had to put in new gears and I don't have something correctly aligned/positioned in the rotation cycle.

Im not 100% sure what is wrong,butI did do something a while back when I had my 86,to get the headlights to flip correctly in the on/off positions.
I did some repairs and one side got stuck down and the other would open.

Basically one headlight would open when pulling the switch to ON and the other stayed closed...the closed one lighted up but would not spin open when turning it on.

I tried unplugging the motor harness up front at the stuck headlight area and it reset it back.Maybe have to try both sides with the on and off positions being used.Just something to try to reverse the polarity of the magnetic motor it has in there.

See,if you take apart the motor,the magnets inside push/pull to either open or close.You may have installed the motor back in after the gear change into the open position,and when you turned it on,it flipped back over to close,and stayed closed.Make any sense?

If you turn the lights on,and one side stays closed,unplug the motor harness clip and then plug it back in...it should flip back open.

Hope this helps some...been a few years since I did it,hope I got it right from memory.

Reading it again,you may have to manually turn the **** to its fully opened position BEFORE turning the headlights ON.I may have misunderstood ya the first time.Open them by hand at the **** until it stops in the open position and pull the switch to ON.

If it makes it close when on,but in the correct place of it off,then try the unplugging method I used.

If that doesnt work,with the lights off,turn the manual **** until its full closed and wont turn anymore....then pull the switch to ON and see if it spins to the fully open place.

Default I'll Give the Suggestions a Try

I didn't have any time today to fuss with it. I have a shop manual on it's way to my door, maybe it will also have some info on synchronizing the motor to the light position (open or closed). The Chilton I have is pretty non-informative on this issue.

Thanks,

Cheers
Tom

Did you ever get the headlights to open/close properly? I have the same problem with one not closing far enough. How did you fix it?

My '88 FSM only shows where are the three headlight aiming screws but has no info on how to get the assy to rotate to the correct position.
