Question about 1993 Cadillac Fleetwood
Brake lights work when headlites off. With head and tail lights on, applying the brakes turns off the left taillight. The center and right brake lights work fine. The left turn signal works well with headlites on or off, and with the brakes applied. The bulbs have been replaced with the correct 2057. It's a 1996 Deville. Any help will be appreciated.
Hi Ahunley, Sounds like you have cross the connection wires to the unit ( positive to earth & earth to positive) Try swapping the connectors over.
Hope this works.

SOURCE: right and left brake lights
check the brake light switch located in the brake pedal area. Normal procedure is to remove the two wires and connect a jumper' wire between them, check and see if the rear brake lights operate. Check the brake light switch and see if it is adjustable. If so, re-connect the removed wires, adjust the position of the switch untill the brake lights operate,when the brake pedal is depressed, then secure the brake light switch.

SOURCE: Hello, I have a 97
Now remove the bulb & put your volt meter to the
center socket contact & ground your blk lead.
See if you get 12.6 volt back to the socket
If not,then you have a voltage drop before the socket
I hate to suggest a wiring diagram, as your doing good
so far,BUT you may need one, after you get dirty under the
car some more following the wiring
