ON-VEHICLE INSPECTION
1. INSPECT REFRIGERANT PRESSURE WITH MANIFOLD GAUGE SET
HINT: This is a method where a manifold gauge set is used to help locate the problem.
(a) Read the manifold gauge pressure when the following conditions are established.
Test conditions:
-
Temperature at the air inlet with the switch set at RECIRC is 30 to 35°C (86 to 95°F).
-
Engine is running at 1500 rpm.
-
Blower speed control switch is at "HI".
-
Temperature control dial is at "COOL".
-
A/C switch is ON.
-
Doors are fully open.
(1) Normally functioning refrigeration system
(2) Moisture is present in refrigeration system.
(3) Insufficient cooling
