Some 2001-’04 Sequoia and 2000-’04 Tundra vehicles may exhibit a condition where the air conditioning system does not sufficiently cool the cabin. Adjustment of the water control valve is necessary to correct the condition.
Repair Procedure:
1. Turn the temperature control knob to the full cold position.
2. Inspect the clearance between the water control valve lever and the lever stop. If the lever does not contact the lever stop, proceed to step 3.
See Fig. 1.
3. If the lever does not contact the lever stop:
a. Disengage the cable retaining clip.
b. Pull up on the cable sheath until the water control valve lever contacts the lever stop.
c. Re-fasten the cable-retaining clip.
See Fig. 2.
4. Cycle the temperature control knob several times and confirm proper water control valve adjustment.
