INSPECTION
1. INSPECT HEATER RADIATOR
If the fins are clogged, clean them with compressed air.
2. INSPECT BLOWER MOTOR OPERATION
Connect battery positive (+) lead to terminal 1 and battery neg-
ative (-) lead to terminal 2, then check that the motor rotates
smoothly.
If operation is not as specified, replace the blower motor.
3. INSPECT AIR MIX SERVOMOTOR (See page DI-1354)
4. INSPECT AIR MIX DAMPER POSITION SENSOR
(See page DI-1345)
