To Replace:

• Remove the headlight bezel retaining screws. Remove the bezel. If necessary, disconnect the turn signal lamp wires.
• Remove the retaining ring screws from one or both lights.
• Remove the retaining rings.
• Remove the light from the housing. Disconnect the wiring connector from the back of the light.
• Push the wiring connector onto the prongs at the rear of the new light.
• Place the new light in the headlight housing. Position it so the embossed number in the light lens is on the top.
• Place the retaining ring over the light and install the retaining ring screws. Tighten them slightly.
• Check the aim of the headlight and adjust it, if necessary.
• Install the headlight bezel. Secure it with the retaining screws.
• Connect the turn signal lamp wiring (if it was disconnected).

Check fuses & bulbs first, The headlight bulbs may be twin filiment type in which case the lower filliment may be blown & the upper filliment or highbeam will still work in this case replace your bulbs. But these models are renowned for having negative earthing problems. Follow the negative (-) or black lead from the battery to the point it is bolted to the vehicle. make sure there is good metal on metal contact with the negative lead & the vehicle. Then check the negative that comes out of the lowbeam headlight socket insure clean metal on metal contact. If you still cant find a fault, contact a chevy technician.
