Check

To check that the hoses that drain condensation from the evaporator have not become clogged, proceed as follows:

1.	Allow the car to idle.

2.	Set the temperature to LO on both sides.

3.	Make sure that the fan is running at MAX and that air is only administered from the panel vents.

4.	Close all the vents, including the rear vents.

5.	Check that air is blowing or water is running out of the hoses on both sides under the car. If no water or air comes from the hoses, the hoses must be cleaned. Refer to Cleaning the drainage hoses, heating and ventilation unit .
