Default Headlight motor problem 1990 c4

So recently I replaced my headlight module and also replaced the driver side headlight motor and I notice after that the headlights started moving but after a few turns my passenger motor went out and stop moving then it just completely went dead so I assumed it was the motor and I decided to replace it today. after some work I put everything back together but still the headlight will not turn but my driver side does and my light shows as well I’m really unsure what happen maybe it could be with the wiring?

Can you manually move the headlight by turning the **** on the motor. If you cant something jammed mechanically. If you can then id check for power at that headlights connection

You know this how?


There is a reason why the used modules get sold for a high amount. But sounds like you will get it figured out.

I went through this a couple of years back on my '90.

I thought i was the headlight module, so I bought a new one.

Unfortunately, only thing available new was a Chinese import.

It lasted a day or so before the solder fried. And even still, only one headlight rolled.

Bought a used one from a forum member and the headlights have worked fine ever since.
