Steps
Open the rear lamp access
Open the liftgate and remove the interior access panel behind the taillight. Identify the socket for the failed reverse or turn-signal bulb.
Replace the bulb
Twist the socket counterclockwise and pull it from the lamp. Remove the old bulb, fit the correct replacement type, and avoid touching the bulb glass.
Lock the socket in place
Align the socket tabs with the lamp housing and twist it clockwise until secure. Check that the seal sits properly and reinstall the access panel.
Test the repaired lamp
Turn on the reverse or signal function with help from another person. Confirm the correct lamp illuminates and no other rear lights were disturbed.
Check your vehicle’s repair manual for exact specifications and fit.
