My 1987 245dl. Brake lights dont't work. Thought it was the Bulb Failure Relay. Swapped with a newer junkyard one. Nothing happened. I Crossed The Brake Pedal Switch wires. Still no lights.(crossing pedal switch wires would activate ?) I pulled off a headlight and the bulb failure light activated. Put back in, no Light on anymore. So I assume it works. What else canI test. I cleaned all Fuses. Although ocassionally the Turn signals dont work untill I juggle the Fuse that correspondswith it. Strange. ? Previously to the No Brake lights . My left frnt running light and left rear tail had an intermitent non functiong . They have not acted up since fuse cleaning. ?? Any suggestion sHighly appreciated. Thanks in advance.
