PWR. WINDOW/PWR. DOOR LOCK BUTTONS MAY CRACK (REPLACE)

SUBJECT: POWER WINDOW AND POWER DOOR LOCK BUTTONS MAY CRACK (REPLACE WITH NEW BUTTONS)

VEHICLES AFFECTED: 1990-91 PONTIAC GRAND PRIX

Condition:

----------

The power window and power door lock buttons on the 1990-91 Grand Prix sedan may crack or deteriorate.

Cause:

------

The process by which the buttons were made may cause the buttons to deteriorate over time. Sunlight could make the condition worse. The process was changed, and new buttons went into production in April of 1991.

Correction:

-----------

A kit, P/N 10220687, has been released containing two power door lock buttons and seven power window buttons.

The buttons can be replaced without removing the switches from the doors. To replace the buttons, use a tool such as a small screwdriver to gently push in the side of the old button, which allows it to pop out. Make sure the small springs stay in place. Then snap the new button in place.

For vehicles repaired under warranty use:

They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition.
