The covers on the headlights of my 1990 Le Baron do not work. I know the motor is good as I hooked it up directly to 12volts and reversed it. They both close and open. Any idea what to look for or check next ? Thanks...

The relays, they will either be in the fuse box under the hood, or inside under the steering column. Use a test light to see if they get a power signal to open/close the doors when you turn on/off the lights. I forget, the power signal may be negative or postive so test for both. If they dont get a signal, I'd say the body computer is bad, however, out of several EEKs with similar issues, I have yet to see one that actually had a bad computer of any kind. They rarely go bad. It's more likely the wiring.
