Do your headlights go up and down OK if the hood is open and the mechanisms are getting no resistance from the headlight doors? if this is true then here are a couple suggestions:
1) Put a couple drops of 3-in-1 oil on the pivot bolts that the headlight mechanisms rotate about when going up or down. In addition to this:
2) The headlight doors have a couple rub pads that the headlight mechanism is in contact with to push the headlight doors open. Open your hood with the headlights down and spray these rub strips with a couple heavy coats of silicone spray.
In short term maybe... long term most lube will:
Trap dirt etc and "wick" crap into pivot points.
Most HL pivot point and door sliders use Plastic bearings. Most oils/grease will kill them. (Brake/clutch pedal bushing have same issue.)
GM used dry plastic bearings so dirt etc won't build up and do damage that can kill HL lift system.
WORSE... Likely Won't do anything to gen 2 system.
Most likely Module is:
killing power as soon as HL switch is on. Cause by dead bushing, motor need lube, etc.
dead gear "bushing" can hold a load sometimes, other time motor just spin for ~5 sec then module times out.
