Chevrolet Repair Questions? Ask a Mechanic for Answers ASAP
Do you have access to a test light or voltmeter?
Have someone press brake and test voltage on Green wire at right rear taillight connector. Do you have voltage there?
Also try the hazard flasher. Does the right rear light up with hazard flasher?
Next you will want to check wiring under dash at column. Test green wire coming out of column for voltage as you did before. If there is no voltage present, the turn signal switch is faulty (brake light voltage comes through turn signal switch as well). If you do have voltage, repair the green wire between the column and the rear of the vehicle.
