Customer Review

Reviewed in the United States on May 5, 2019
Purchased for 2003 Tahoe with Aux Temp Control (CJ2), Aux Heat (C36), and HVAC A/C Rear (C69).

This unit is noted as a direct replacement for a superseded part (15832319) of the original part (15185966) in my vehicle.

Control unit was easy to replace. It actuates the blender doors as expected. It appears to fully support the "AUTO" temperature and "AUTO" floor/ceiling settings as expected. When the front controls are set to "AUX", it reacts properly to the second seat controls as expected.

It does not, however, turn off the rear blower automatically when the engine is turned off and the key is removed from the ignition. This was the behavior of the control module that this module replaced. This will necessitate manually turning the fan motor on and off whenever the engine is started and stopped.
