This just happened last night so Im putting the question out there so I can look at it this Holiday weekend. 86GT, but I have the 2nd gen 88 headlight motors. The passenger side decided it didn't want to go up. I just put these in last summer and I replaced the common plastic bushings when I put them in. Whats my most likely issue. Thanks

When you turn on the lights, does the motor run but won't lift the light?
Or, can you start to raise the light manually by turning the knob a little, then activate the switch and make it go up by itself?
Does it go down by itself if it's raised?
Answers to these may help in diagnosis responses.

Try... See my Cave, Gen 2 HL Motor

maybe... Screw at bottom has a small loose ball bearing.
clean and lube the bearing.
Adjust so motor shaft has a tiny bit of play. Never "preload" the bearing.

I had a similar problem about a week ago on my Formula. Mine would go up if you manually turn the knob to loosen it slightly. My gear was cracked down the middle.

Thanks for the tips guys. It gives me a place to start looking. Im off the next 4 days, if it ever stops raining. I do know that the motor doesn't run when I go to manually put the light up.

Looked at this today. Plugged passenger side into driver side and motor works perfect. Did voltage test at plug. Not getting 12 volts at the passenger side plug. Module must be bad. There's nothing else it could be. Odd that the driver side still works though.

The module acts as an Isolation Relay. Each motor is on a separate part of the module, otherwise when resistance builds on one, the other would stop, too, even though it might not be completely up or down.

Not really. One side doesn't know when other side is dead.

Caution: "Dead" module can still be a iffy motor or a short in wire to the motor.
P side wire goes around radaitor etc and edges can cut into wires.

I checked the wires and there are no raw spots, pinches, or crimps. There is no power to the plug on the passenger side when motor is unplugged and we turn on the lights. Passenger motor works perfectly on driver side. So I think that eliminates all of those objections.
