Buick Regal tail lights diagram

Unread post by Tampa1234 » Fri Oct 17, 2014 10:26 pm

2003 Buick Regal Ls model Vin. K,, all my lights work except my tail lights. All headlights, brake lights, turn signal, dash lights, and interior all work fine but no tail lights. I've replaced fuses even went as far as replacing dimmer, multifunction switch , and bulbs.... NO LUCK.. can someone tell me if theirs a relay for tail lights or what can be the cause of problem... Thanks

there is a relay. park lamp relay behind the right side dash. however, it is controlled by the body control module. the headlight switch sends the signal to the body control module and the BCM send the signal to the park lamp relay and the relay send the power to the park lamps.
