I have a 1992 Trofeo...the headlight doors close and stop perfectly, however, when they open the motor does not turn off for about 3 seconds AFTER they are fully open. The result is series of three (or so) "thunk, thunk, thunks! Any ideas? My thought is the electronic control unit mounted under the fuse/relay box adjacent to the windshield washer reservoir....which probably is only available in the junkyard.

Thanks,

Gary
