1 brake turn light not working

if it's flashing fast you have another bulb out in the front. or the wrong type of bulb.

front is flashing nothing to rear stop or turn.

use a test light & see if you have power when the brake is applied. also check inside the socket for a good connection to the bulb .

no power to the plug just ahead of the socket.

Keep tracing back toward the front of the vehicle.

anyone have a wiring diagram they can forward on to me?
