Dealer Technical Bulletin 68-T-6 – Air Entering Passenger Compartment Around Inside Door Handle – 1968 Grand Prix, Bonneville and Catalina
Bulletin 68-T-6 — Pontiac Motor Division Dealer Technical Bulletin, Section 2, dated November 10, 1967. Attention: Service Manager.
Subject: Air Entering Passenger Compartment Around Inside Door Handle — 1968 Grand Prix, Bonneville, and Catalina.
Short answer: On some 1968 Bonneville, Grand Prix, and Catalina models with the leather trim option, an objectionable amount of air may enter around inside front and rear door handles. The fix is to cement a polyethylene sheet over the remote control access hole on the back of the door trim assembly, then seal it with cloth waterproof tape.
If this condition is encountered, correct it using the following procedure:
- Remove door trim assembly.
- Remove door remote control handle.
- Using 3M vinyl trim adhesive, cement a piece of polyethylene sheeting (approximately 18″ × 20″ × 2 mils) to the back of the door trim assembly over the remote control access hole, as shown in the illustration on the reverse side.
- Apply cloth waterproof tape around the outer perimeter of vinyl pocket.
- Install door trim assembly.
- Install remote control handle.
- Install remote control cover plate.
Use the flat rate operation for R&R trim assembly, plus 0.1 hour for each door.
