Right Temperature Door Motor (V159)

Right Temperature Door Motor (V159)

with Right Temperature Door Potentiometer/Actuator (G221)

• You can check the adjustment motor's function via the "output diagnostic test mode" using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function or check it without a tester as follows: if not using a tester, connect both contacts 5 and 6 on the adjustment motor's connector to a 12 volt DC source. The adjustment motor will move in one direction up until the stop, and will reverse direction if the plus and minus contacts are switched. Use an adapter cable. Refer to => [ Adapter Cable for Activating Control Motors ] Adapter Cable for Activating Control Motors.

• Perform a basic setting to the A/C (heating) system after installing a new motor using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• Using the functions "Output diagnostic test mode" and "Basic setting", the activation of A/C system electrical components can be tested if necessary (e.g. allocation test) using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

• On the Audi TT with A/C system, both motors for left and right temperature doors are controlled via one characteristics curve, depending on the programmed end stops (only one temperature setting on the Climatronic control module (J255) is possible).

• Depending on the measured temperatures, the calculated sunlight intensity and setting on Climatronic control module, the calculated specified outflow temperature and therefore, the specified position of the positioning motor, may be different for the left and right side.

• On the Audi TT with heater (without A/C system), only one temperature door motor is installed. Both temperature doors for the left and right sides are connected via a shaft and moved together by the Left Temperature door Motor (V158).

Removing

- Remove the glove compartment.

- Remove front passenger side footwell vent - A - (in order to improve accessibility to control motor - B -).






- Remove bolts - B -.






- Remove control motor - C -.

- Disengage control motor lever - E - from connecting rod - D -.

- Disconnect the connector - A -.

Installing

• Lever - E - on control motor and connecting rod - D - are color-coded, they are colored black for Right Temperature Door Motor (V159).






Reinstall all removed components in the opposite sequence while observing the following:

- Install the wiring harness so that it cannot come in contact with any moving parts (e.g. the actuating arm of the control motor).

- Check Climatronic control module (J255) DTC memory and erase any possible displayed malfunctions using Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.

- Perform a basic setting and output diagnostic test on the A/C and check the DTC memory one more time. Refer to Vehicle diagnosis, testing and information system (VAS5051B) in the "Guided Fault Finding" function.
