Technical Procedure

HEADLIGHT SWITCH:

NOTE: EACH SUSPECT PUSH-PULL HEADLIGHT SWITCH MUST BE INSPECTED. IF THE ALPHABETICALLY MARKED HEADLIGHT SWITCH CAVITY HAS EITHER A "D" OR "M" IDENTIFIED, THE SWITCH MUST BE REPLACED. REFER TO ILLUSTRATION. (THE HEADLIGHT SWITCH CAVITY IS ON THE OPPOSITE SIDE OF THE SWITCH FROM THE DATE CODE).

1. Disconnect the battery negative cable.

2. Remove the Headlight Switch. Refer to Page 8C2-4 of the 1986 Buick Chassis Service Manual.

3. After removing the headlight switch from the Instrument Panel (I.P.), refer to the illustration to locate and identify the cavity code.

a. If the cavity code is a "D" or "M", replace the switch using the correct part number, per the Parts Information section.

b. If the switch does not have the suspect alphabetical cavity codes, reconnect the existing switch. Proceed to Step 4.

4. Reassemble the headlight switch per the Chassis Service Manual instructions.

CAMPAIGN IDENTIFICATION LABEL:

5. Install a Campaign Identification Label.

Each label provides a space to include the campaign number, the five (5) digit dealer code of the dealer performing the campaign service, and the date vehicle was campaigned. This information may be inserted with a typewriter or ballpoint pen. When installing label, clean the surface of the radiator support tie bar. When installing label, clean the surface of the radiator upper mounting panel and apply the campaign label where it is readily visible.
DISPOSITION OF PARTS

Replaced parts must be held for disposition by Buick contact personnel. Parts must have a claim tag attached showing the repair order and the VIN of the vehicle from which they were removed.
