My headlight covers open and close on my 1992 Trofeo, but they make a noise afterward as if they are still trying to open or close. It lasts a few seconds but is very annoying. Where is the control module located? Can it be the problem?

I would check the headlamp door open and close relays first. One or both of them may be bad. It might be a bad headlamp door motor assembly as well. Is there anything blocking the doors from closing all the way? Have you tried closing and opening them manually? You can remove the rubber boot from the door motor knob and turn it by hand.

Have you checked the circuit breaker for the headlamps? It is in the fuse panel in the glove compartment. Should be 20 amps, probably in position 22. You'll most likely have to replace it with a known good one; there's no way to tell if it's bad just by looking at it. If that doesn't take care of the problem, it could be in the headlamp switch, the dimmer switch, or somewhere in the wiring.
If one headlamp was out, it would be easy. With all four out, it gets a bit more complicated. If your Trofeo has Twilight Sentinel, it a WAY more complicated. If replacing the circuit breaker doesn't work, I would recommend finding a shop manual (eBay is a good source) and following the diagnostics.

I woukld suspect the headlight switch is defective and the connector to it is burnt, a common problem in this year.

try using (led) lights thay last ten times longer than regular lights hope this helps

There is a small panel in the headliner (usually all the way back by the window) that if you remove it will reveal a mechanism you can use to crank it closed by hand.

I have the same problem with my 93 Salon. Take a look at the torsion bar rod end close to each headlight.There are collars that have a set screw which can be loosened to adjust the range of the door opening and closing. If the doors are going through the full cycle open to close but fall back and leave a gap such as you describe, most likely you will only need to adjust those screws. Each door will require adjustment individually. May require an allen wrench. Hope this helps.

Do you hear a clicking noise as if it is trying to close? If so, it may be the gear located in the h/light motor housing that needs replacing. You can purchase these for anywhere from 24.99 - 65.00 each, online. Hope this helped.

When you open the hood you will see a cover where the hood latch is. Some covers have individual doors on each side of the hood latch. If you have that type just pop the release on the cover and reach down to the headlamp bulb. It comes out with a twist with the socket and then pull the bulb free. Use a kleenex or gloves to install new bulb and reverse the process.

If the whole panel is one piece there are some plastic button holders to remove to lift the cover. Your headlights are underneath. In some cases the passengers side headlight may require removing the battery to access. Then just twist the socket and remove the bulb afterwards, then reverse process.

If both have failed at the same time, it can only be a fuse or failed relay. The motors are probably fused separately from the headlights themselves.

sounds like a loose connection. check your harness at the healights make sure they are tight and nothing got knocked loose
