1. INSPECT FOR LEAKAGE OF REFRIGERANT
(a) Remove the glove compartment door.
(b) Remove the lower No. 2 finish panel (BO-84 ).
(c) Remove the No. 1 cooler cover.
(d) Using a gas leak detector, check for leaks of refrigerant.
If there is a leakage of refrigerant, check the tightening torque at the joints or check the evaporator.
(e) Install the No. 1 cooler cover.
2. INSPECT EXPANSION VALVE
(a) Check amount of gas during refrigeration cycle.
(b) Set on manifold gauge set.
(c) Operate A/C system at "MAX. COOL" for approx. 5 minutes.
(d) Check expansion valve.
Check the low pressure reading drops to 0 kPa (0 kgf/cm2, 0 psi).
If the low pressure reading is not as specified, replace the expansion valve with the tubes.
Reassembly is in the reverse of disassembly (AC-76 ).
