okay for the bulb
1. If your replacing the left(driver's side) headlight bulb, remove the fuse and relay box mounting bolts, disengage the box from the battery tray and slide it toward the engine to provide some room to work.
2. Rotate the locking counterclockwise and then remove the headlight bulb holder from the headlight housing.
3. Disconnect the headlight bulb holder from the electrical connector.
4. Remove and inspect the old bulb holder O-ring and inspect it for cracks, tears and deterioration. If its damaged, replace it.
5. Installation is the reverse of removal.
And for the whole headlight housing
1. Remove the push pin that attaches the headlight seal to the fender.
2. Remove the headlight mounting screws.
3. Pull out the headlight housing far enough to remove the bulb holders for the headlight bulb and for the turn signal bulb.
4. Remove the headlight unit from the vehicle.
5. Installation is the reverse of removal.
