In the event of customer comments on heating and/or cooling not meeting their expectations are encountered on the above styles equipped with C60 air conditioning, the following procedure should be used to correct the condition:

1. Lower glove compartment to gain access to the control cable turnbuckle. (Refer to Figure 1)

2. With control at full cold position, adjust turn buckle until temperature door just comes to a stop on the left.

3. Move control to full hot position and feel if door is held against right side.

4. If not, adjust turn buckle until door just stops against right side.

5. Recheck cold side to assure door is tight against stop on left. If not, repeat Steps 1 thru 4.

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.
