TEMPERATURE CONTROL OR HEATER-A/C LEVERS LOOSE OR BINDING - REPLACE CONTROL HOUSING
MODELS/YEARS
1991-92 BRAVADA
Some 1991-92 Bravadas may exhibit loose or binding temperature control or Heater-A/C mode selection levers. These conditions may be caused by
broken housing bosses at the plate mounting screws on the A/C control. The result may be inability to actuate certain Heater-A/C modes or obtain
maximum heating or cooling.
Previously it was necessary to replace the complete A/C control assembly to correct this condition. The control assembly included the valves, switches,
bezel and lighting.
The housing, P/N 16074394, is now available allowing this condition to be corrected when other parts of the control are operating properly. Partial
disassembly of the A/C control is required.
SERVICE PROCEDURE:
1.
Remove the A/C control assembly from the instrument panel.
2.
Place the Temperature and Mode controls in the upper position.
3.
Apply thumb pressure to each of these control knobs to hold them in the upper position while using a small screw driver to pry off the knobs
(Figure 1).
4.
Use the same procedure to remove the blower switch knob.
5.
Disconnect the 2 light sockets from the housing by twisting the sockets counterclockwise.
6.
Remove blower motor switch.
