I HAVE A RELATIVELY MINOR PROBLEM THAT IS ABOUT TO DRIVE ME CRAZY!!
I HAVE A 1986 420 SEL- MY PROBLEM IS THIS:
MY POWER SEATS ONLY FUNCTION WHEN ONE OF THE FRONT DOORS IS OPEN, REGARDLESS OF WHAT POSITION THE IGNITION SWITCH IS IN.

CLOSE THE DOOR, NO PWR SEATS, EVEN WITH THE IGNITION SWITCH ON.

I TRIED A QUICK FIX BY JUMPING THE 2 WIRES ON THE DOOR SWITCH, SO THE SWITCH WOULD BE "FOOLED" INTO THINKING THE DOOR WAS OPEN...TURNS OUT I WAS THE FOOL AFTER DISCOVERING A DEAD BATTERY AFTER A WEEK WITHOUT DRIVING.

THERE IS NO MENTION IN THE CHASSIS MANUAL AND VERY LITTLE TO GO ON IN THE ELECTRICAL TROUBLESHOOTING MANUAL. I CANNOT SEEM TO TRACK THE PROBLEM DOWN. I HAVE PULLED THE INSTRUMENT CLUSTER, UNPLUGGED THE HARNESS FROM THE IGNITION SWITCH, FOLLOWED THE WIRES UNITL I COULD NOT ANYMORE, AND NO PROBLEMS WERE FOUND. (AT LEAST EVERYTHING LOOKED OK)

I EVEN REPLACED THE WARNING BUZZER SWITCH ON THE STEERING LOCK(I KNOW IT CONNECTS TO CENTRAL LOCKING, AS WELL AS THE WARNING BUZZER) NO LUCK, BUT NEEDED REPLACED ANYWAY.

BTW, THE ONLY TIME THE WARNING BUZZER SOUNDS IS WHEN I LEAVE THE HEADLIGHTS ON.

I KNOW THIS SEEMS SMALL, BUT IT WOULD BE NICE TO BE ABLE TO ADJUST MY SEATS WHILE GOING DOWN THE ROAD.

ANY HELP WOULD BE APPRECIATED.

THANKS
