I have an 88 Trans AM with a 5.0 TPI and my driver side headlight motor doesn't work. Here's the catch if I connect it to the passenger side it works! So the motor itself isn't the problem. I checked fusible links along the steering shaft and they looked good. I even checked for current with a test light and there's current from the module to the connection to the motor. What's the problem I'm confused. If there's a relay or fuse I haven't checked please let me know and upload a photo that I could use to locate it.

 

I'd say the headlight control module is the problem. The module you need is a bit harder to find used because it was only used for 3 model years (87-89). I have plenty in stock if you can't find any.
