Help! 1990 c4 headlights

[1990VETTE]

I just recently changed the bushings and gears in my headlight motors because the lights only went up half way. The instillation was a success except that now only one headlight goes up. The other headlight motor doesn't even run. I jumped that headlight with the power from the headlight that works and it went up. So now I know that the headlight motor is good. Here's the big question, How can I tell if the headlight actuator is good or not? Can there be something else wrong that I'm overlooking?

My guess is that the headlamp relay module is bad!! It's on front of left front splash shield!!(About 4 X 4 X 1 1/2 inch black box 2 wire bundles plug in it!!)

C4 HEADLIGHT PROBLEM

Thank you for the info, I had this feeling that the relay might be a problem. I was hoping that it wasn't because it's about $230 dollars. Is the Actuator or relay the same thing? If i purchase it I want to make sure I purchase the correct item.

1990 headlight problem

I looked this part up on ecklers web site and they called it Headlight Opening Actuator Module, and it was $190.00 The picture was the same as the one you showed me. A lot of money for such a simple part. Any part dealers that might be cheaper?

wow thats a BIG difference in price. I'm suprised. I think I should be visiting GM more.

It seems the catalog guys may be charging vette tax as well.
