DTC Description: Description

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

COMPONENT DESCRIPTION

The front mode door motor is attached to the heater & cooling unit assembly.
The front mode door motor consists of a motor, gears, shaft, a Position Balanced Resistor (PBR), and a Local Control Unit (LCU).
Motor rotation is conveyed to a set of links which activate the defroster, vent, and floor mode doors. It rotates so that air is discharged from the outlet set by the front air control.
The LCU determines the front mode door position via feedback from the PBR and sends the position information to the front air control.
