Hi renshitos,

Seems the heater valve or air mixed cable are not functioning correctly and they would affect the A/C operations. You need to check if the cables are dislodged or broken.

Perform the folllowing checks and adjustment o see if you can come up with anything.

ADJUSTMENTS
AIR MIX CABLE

Disconnect air mix cable from air mix control arm and clamp. See Fig. 2 . Set temperature control lever to maximum heating. Move air mix control arm downward (away from cable clamp) and connect end of air mix cable to arm. Gently slide cable outer housing back enough to take up slack in cable, but not enough to move arm. Snap cable housing into clamp. Adjust heater valve cable.

HEATER VALVE CABLE
1. Disconnect heater valve cable from heater valve arm (in engine compartment) and from heater control arm and clamp (inside vehicle). See Fig. 2 . Set temperature control lever to maximum heating.

2. Move heater control arm upward (away from cable clamp) and connect end of heater valve cable to arm. Gently slide cable outer housing back enough to take up slack in cable, but not enough to move arm. Snap cable housing into clamp.

3. Turn heater valve arm toward cable clamp and connect end of heater valve cable to arm. See Fig. 2 . Gently slide cable outer housing back enough to take up slack in cable, but not enough to move arm. Snap cable housing into clamp.
