SYMPTOM/CONDITION
Warm air coming from the side window demisters when the climate control system is operating in the A/C panel mode.
DIAGNOSIS
Before attempting further repairs, it is important that the following action be taken to insure this condition is not caused by a misadjusted temperature
door.
1.
Verify that the temperature door is hard against its stops when the temperature setting on the A/C control panel is in the coldest (not recirculate)
position. On standard A/C, this can be done by rapidly moving the lever to the minimum heat position. On Auto Temp systems, it will be necessary
to set the control to 66 degrees. When correctly positioned, the door will emit a "thump" as it hits its stops. If necessary, adjust the cable
auto-adjusting clip to obtain the desired results.
2.
With the engine idling in park or neutral, operate the climate control system in the A/C panel mode at high blower speed and at minimum heat (not
recirculate) until the A/C discharge air and engine coolant temperatures have stabilized.
3.
Measure the temperatures of the left center A/C outlet and the demister outlet. If the demister air is more than 20 degrees warmer than the A/C
outlet air, the bi-level air door and vacuum actuator should be replaced.

REPAIR PROCEDURE
This repair procedure involves replacement of the bi-level air door and vacuum actuator which will reduce the temperature and the volume of the
demister air anytime the system is in the A/C panel mode.
1.
Consult the appropriate 1988 service manual for the proper procedure and then remove the A/C evaporator housing from the vehicle.
2.
Using the procedure as outlined in Group 24 of the service manual, remove the bi-level air door and vacuum actuator from the evaporator housing.
