If I can do it in my S10 on the A/C side, we can get it done on that thing. If you want my skinny hands to help, give me a holler and we'll get it done.

Dang, has it really been that long since I worked on this thing??

I decided to try tackling the headlights today. I watched the ChrisFix video on youtube, https://www.youtube.com/watch?v=sPj1kJm4AnU

I had already purchased a kit from Amazon with the brass gear and nylon bushings. I started with the drivers side. I got everything taken apart pretty easily. You need a couple T30 torx, a 10mm and a 1/4". When I got everything apart and removed the cover, I was surprised at how clean it was. The gear itself was fine. But the nylon bushings were all crumbled.

I got it put back together without too much drama -- I thought "why did I wait this long to try this??" But, when I did my test, I get nothing. The light turns on, but no action from the motor. The un-touched passenger side one half-flips. I know there is a 2-wire connector for it, and its connected. I didnt try anything before I took it apart, so I dont remember how well it worked/didnt work. More to come..

the first thing I would do is find the ground wire connection and clean it. there is some notoriety with bad grounds on C4s

you can also turn it by hand to raise the light to make sure nothing in the mechanism is bound up

C4. C5. Whatever it takes!

A little progress tonight. I applied 12v directly to the headlight motor, and it works. And it moves exactly like it should.

So I guess there is a headlight actuator relay thing mounted right in front of the left front wheel. It sends the power to both sides individually. Might have to replace that.

I removed the passenger side headlight assembly and got the gear replaced in there too. Like the drivers side, the gear was good, but the bushings were ground to dust. However, the rollpin split in pieces and I dont know if I have another one. But I'm on the re-assembly phase, so I should have working headlights very soon.

Feels good to make some progress on this car.

I finished the passenger side headlight today and got it back in the car. It works good now. I have the headlight actuator on order from ebay. I was hoping it would be here this weekend. Once that is in, the headlights should be 100%.

I got the headlight actuator relay and installed it. With the hood up, both lights work as expected, yay! But when I closed the hood, now the passenger side is hitting something and not able to fully open. Hopefully just an easy adjustment, but it seems odd.

Next up are the header gaskets. Passenger side is blown out bad. That's the main reason I haven't been driving it. Of course, it's the harder side to do, but I'll just do both of them. I'm thinking about sending the headers out to have them ceramic coated. Even with what looks to be angle-plug heads, the spark plug boot is just too close.

I've had trouble with the radiator overflow hose obstructing the passenger side headlight. from the factory there are several loops to hold it in place but if any have been removed the hose can shift.
