Steps
Remove upper shields and bumper fasteners
Open the hood and remove the upper shields and weatherstrip retainers. Release the lower and wheel-well clips, disconnect the fog-light harness, and move air ducts as needed.
Free washer hoses and bumper
If headlamp washers are fitted, disconnect the hose carefully and cap it to limit fluid loss. Release the bumper side guides and mounting bolts, then support and remove the cover.
Replace the fog-light assembly
Remove the lamp fastener and release its locking tabs. Fit the replacement into the bumper opening, align its guides, and secure it with its retaining fastener.
Restore bumper components
Reconnect fog lamps and washer hoses, then reinstall the bumper, air ducts, shields, and wheel-well clips. Check that every hose and harness is routed clear of moving parts.
Test lamp and washer
Turn on the fog lights and verify the new lamp illuminates. If equipped, test the headlamp washers and inspect the hose connections for leaks.
Check your vehicle’s repair manual for exact specifications and fit.
