Headlight housings are expensive to replace, but repair kits are available at Toyota dealerships that can save a headlight housing with broken mounting tabs. For 2001 through 2003 models, begin by removing the engine bottom cover and the front bumper cover, then take out the two upper bolts and the nut at the bottom of the fender. Disconnect the electrical connector and lift the headlight out, with installation being the reverse of removal while ensuring to check headlight adjustment. For 2004 through 2009 models, remove the fender inner liners and the front bumper cover, then take out the three fasteners from the headlight assembly. Disconnect all wiring and lift the headlight out, again installing in reverse order and checking headlight adjustment. For 2010 and later models, start by removing the radiator top cover and the front bumper cover, ensuring it is disconnected enough to access the bolt at the lower rear of the headlight. Remove the two top screws and the lower bolt from the headlight housing, carefully releasing the clip at the front corner, then release the wiring harness clamp and disconnect the electrical connector, with installation following the reverse of removal.
