I have a 2000 Mercury Sable with a dim right headlight. When plugged the assembly in on the other side it worked properly. Any idea how to repair?

CIRCUIT 13 (RD/BK)
Place the headlamp switch in the ON position.
Place the multifunction switch in the high beam position.


Do the high beams operate correctly?
Yes
REPAIR circuit 13 (RD/BK). TEST the system for normal operation.

No
For LH headlamp, REPAIR circuit 160 (DB/WH). TEST the system for normal operation.

For RH headlamp, REPAIR circuit 161 (DG/OG). TEST the system for normal operation

I made a mistake, with the dim side. The problem is on the left side with the headlight and the highbeam; they are both dim. The directional and the parking light work properly. Can you help with the circuits?

Thank you
