TEMP. LEVER:EXCESSIVE EFFORT CABLE NOT ROUTED CORRECTLY

MODELS: 1986 S/T TRUCKS

Some 1986 S/T model trucks may experience excessive high temperature lever effort.

This conditon may be caused by incorrect temperature cable routing and/or incorrect cable attachment to the temperature door.

To verify correct cable routing and attachment, the following checks should be made:

1. Routing of the temperature cable should be above the glove box as shown in Figure No. 1.

2. The cable should be attached to the temperature door lever with the adjustment clip facing toward the front of the vehicle (See Figure No. 2).

3. The push-on nut should not be pushed down onto the adjustment dip to the extent that rotaflon of the clip on the shaft is prevented (See Figure No. 2).

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". 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. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
