88 formula.

When I turn head lights on only left light goes up. I can manually lift headlight part ways and turn lights off then both lights work properly. For a couple days, then back to lazy eye. Sometimes they work fine. Recently it started a new trick. The parking lights would not come on but both headlights work properly. Today I replaced the headlight switch so maybe the parking light issue is solved.
What direction should I take to find the issue? Does anyone know?

I suspect the nylon bushing things in the headlight motor have turned to white dust. That'll make sense when you take it apart. The other motor is probably about to have the same issue. Go to Rodney's site and find his replacement bushings.

Yep. Time to rebuild the motors. It's a pretty easy job. Just get the rebuild kits, and plan to spend more time taking the headlights out and putting them back in, and re-aligning them, than it takes to do the actual rebuild.

I replaced the bushing with rodnys a month after I bought the car, which would make it a year ago.


I replaced the headlight switch now it seems as both headlights work properly. Note I said seems

Could just be the relay. I'd swap them before I did anything else.

Also check the connector to the headlight relay, one of mine had a loose wire that would sometimes make contact and sometimes not make contact. A good way to check the relay itself is to switch it to the opposite side and see if it works there. They are interchangeable from side to side.

My car has the second gen headlight system. It has the module. I'm not sure if it has one them relays. I will look again.

Opps you are right, 88's had the less complex system
