To Replace a Headlight
(2-DOOR MODELS)
Before replacing a headlight that does
not light, check to make sure that the
wiring connector is securely fastened to
it.
See the
Index under Replacement
Bulbs to check the size and type of
headlight you need to use before you
begin to replace the headlight. You
must replace a headlight with one that
is exactly the same.
1. Open the protective panel above the
headlights.

13. Plug the wiring connector into the
headlight socket. Snap the locking
tabs onto the socket.
14. Lower the headlight assembly into
position. Make sure the two guide
tabs
drop into their holes in the
headlight support panel.
15. Insert the two bottom screws. Make
sure the guide tabs are still in place
before tightening the screws. Use a
magnetic screwdriver or hold the
screw onto the screwdriver with a
small piece
of masking tape.
16. Insert the top screw and tighten
securely. To check
the aim, the vehicle should be
properly prepared as follows:
The vehicle must have all four tires on
a perfectly level surface.
The vehicle should not have any
snow, ice or mud attached to it.
There should not be any cargo or
loading of vehicle, except it should
have a full tank of gas and one person
or
160 pounds (75 kg) on the driver’s
seat.
Tires should be properly inflated.
The horizontal indicator (A) should
read
0 (zero). If
your vehicle
is damaged in an
accident and the headlight aim seems to
be affected, see your Pontiac dealer.
Headlights on damaged vehicles may
require recalibration of the horizontal
aim by your Pontiac dealer.
