I have 1985 Eldorado Barritz HT 4100 that has suddenly has a problem with power seats, door locks and trunk pull down not working? Can't find any blown fuses or a diagram that shows wiring for the power seats? When running and door lock switches are activated the "idiot" light for trunk flashes. Any help would be appreciated.

I believe all of these operate with relays that feed the high-power circuits to the motors/solenoids as requested by the low-power circuits connected to the respective switches. I'd check relays first and wiring second. Maybe look for a common color of wire that shows up at all three locations.

Maybe someone here has a wiring diagram they can post . . . ?
