Evaporator drain hose, removing, checking and installing
Note. This vehicle is equipped with 2 evaporator drains (left and right at air conditioner or center tunnel). There is no flap at valve for evaporator water drain - C -. For complaints of moisture in passenger compartment, check the following components as well as evaporator water drains: - Water drain for plenum chamber --> Plenum chamber water drain, checking and cleaning - Plenum chamber cover for proper installation --> Dust and pollen filter, removing and installing - Check dust and pollen filter for soiling and cover for correct installation --> Dust and pollen filter, removing and installing - Forced-air extraction in luggage compartment --> Ventilation system frame, checking Function of back pressure flap --> Air Flow Flap Motor V71 with Back Pressure Flap Motor Position Sensor G113 , removing and installing and recirculating-air flap --> Recirculation Flap Motor V113 removing and installing Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function. - Measuring values and function of Humidity Sensor G355 at Climatronic Control Module J255. Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function. - Signal for recognition of wiper operation at Climatronic Control Module J255. Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function. Check vent temperature of air from evaporator via measured values of Evaporator Vent Temperature Sensor G263 under operating conditions reported by customer with the following settings on Climatronic Control Module J255 : Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function. - "Temperature Lo" for drivers and front passengers side - Medium fresh-air blower speed (approx. 7 volts) Vehicle Diagnosis, Testing and Information System VAS 5051 in "Guided Fault Finding" function. - "Fresh air mode" If measured value of sensor is too low (at an ambient temperature above 0°C, colder than 0°C for extended period of time) or too high (greater than e.g. 10°C even though A/C system is operating without problems), observe notes for testing cooling output --> A/C cooling output, checking Always check both condensation water drains. The following illustrations show the evaporator drain for the right side of the vehicle. The test procedure is however also always to be performed in the same manner for the evaporator drain on the left side.
