# REVISED: WATER IN HEADLAMPS CHECK VENT TUBES FOR KINKS

#### VEHICLES AFFECTED: 1987 BUICK LESABRE

If a comment is received of a hazing or fogging condition inside the lamp assembly, on a 1987 LeSabre built before December, 1986; it may be repaired by the following procedure:

Disconnect battery.

Remove grille.

If comment received is on one side only, inspect opposite side for any evidence of hazing. Perform the remaining steps on each side affected.

Remove screws and spring holding headlamp housing assembly and pull out far enough to disconnect the bulbs and sockets.

#### CAUTION:

Halogen bulbs contain a gas under pressure. Handling a bulb improperly could cause it to shatter into flying glass fragments. To help avoid personal injury:

Turn off the light switch and allow the bulb to cool before removing bulbs. Leave the switch off until bulb change is complete.

Always wear eye protection when changing a halogen bulb.

Handle the bulb only by its base, and avoid touching the glass.

Do not drop or scratch the bulb. Keep moisture away.

Remove headlamp assembly and place lens side down on a flat surface.

In each socket opening, pour in 200 milliliters (1/2 pint) of DISTILLED water.

#### NOTICE: DO NOT USE TAP WATER AS A VISIBLE RESIDUE MAY RESULT.

Rinse lens and reflector by agitating with lens side down for ten seconds.

Flip housing over and roll water over reflector surfaces.

Shake out water vigorously.

Use a heat gun and heat setting to dry out headlamp housing interior. Dry for about one minute at each socket opening, then dry for an additional two minutes at each opening with the gun set on NO HEAT.

#### CAUTION:

Do not allow the heat gun to come in direct contact with the headlamp housing assembly. Very high temperatures may cause degradation of plastic components and adhesives used in the housing.

Reinstall bulbs and sockets and headlamp housing assembly.

Reinstall grille.

Connect battery.

Reaim headlamps.
