CAUTION:
The excess cooling coil coating will drain when the cap/clamp/plug is removed in the next step.

25. Remove the cap/clamp from the drain tube.

26. On LX/RS/**2005 WH/WK** vehicles (other vehicles proceed to next step), lower the vehicle.

27. Fill each empty cleaner bottle with normal tap water.

28. One at a time, screw each bottle of water onto the applicator tool.

29. Insert the applicator tool into the blower resistor opening.

30. Spray the full contents of the water onto the evaporator continuously while moving the applicator tool up and down and back and forth so that the evaporator is evenly covered with water.

31. Install the blower motor resistor/power module.

32. Start the engine.

33. Raise all the windows to a slightly open position (about 1/2 inch opening).

CAUTION:
In the following step be careful not to damage the A/C cooling coil.

64. Using a suitable object (a wire coat hanger for example), probe the drain tube 3.8 - 5.1 cm (1.5 - 2 in.) to ensure that the dried coil coating is not restricting the flow from the drain tube.
