Control Assembly: Testing and Inspection
Heater-A/C Housing Test
-
ON VEHICLES EQUIPPED WITH AIRBAGS, DISABLE THE AIRBAG SYSTEM BEFORE ATTEMPTING ANY STEERING WHEEL,
STEERING COLUMN, OR INSTRUMENT PANEL COMPONENT DIAGNOSIS OR SERVICE. DISCONNECT AND ISOLATE THE
BATTERY NEGATIVE (GROUND) CABLE, THEN WAIT TWO MINUTES FOR THE AIRBAG SYSTEM CAPACITOR TO DISCHARGE
BEFORE PERFORMING FURTHER DIAGNOSIS OR SERVICE. THIS IS THE ONLY SURE WAY TO DISABLE THE AIRBAG SYSTEM.
FAILURE TO TAKE THE PROPER PRECAUTIONS COULD RESULT IN ACCIDENTAL AIRBAG DEPLOYMENT AND POSSIBLE
PERSONAL INJURY.
Examine all of the heater-A/C housing seals for damage. Replace all damaged or deformed seals. Clean all of the heater-A/C mounting flanges and apply
new sealant prior to reassembly.
Inspect the evaporator coil and heater core for bent fins or other damage. Remove any foreign material or other restrictions to air flow. Repair or replace
any faulty or damaged components as required.
