Driver Door Module: Description

A Driver Door Module (DDM) is used on all models equipped with power locks, power windows, and power mirrors. The DDM houses the following switches:

• Power Lock Switch  - The DDM includes a two-way, momentary, resistor multiplexed switch to control the power lock system.
• Power Mirror Selector Switch  - A three-position rocker switch in the DDM selects the right or left power mirror for adjustment, or turns the power mirror system Off.
• Power Mirror Adjustment Switches  - Four momentary, arrowhead shaped, directional switches allow the driver to adjust the selected power mirror in the Up, Down, Right, or Left directions.
• Power Window Lockout Switch  - A two-way, latching, push-button switch in the DDM allows the vehicle operator to lock out the power window switches on each passenger door so that the passenger door power windows may be operated only from the master switches in the DDM.
• Power Window Switches  - The DDM houses a two-way, momentary power window switch for the driver side front door. This switch also has a second detent in the Down direction and internal circuitry to provide an Auto-Down feature for the driver side front door power window. In addition to the power window switch for its own door, the DDM houses individual master switches for each passenger door power window.

The DDM also incorporates several green Light-Emitting Diodes (LEDs) that illuminate the power lock and power window switch paddles, and the power mirror switch directional buttons to improve switch visibility in dark ambient lighting conditions. The DDM cannot be adjusted or repaired and, if faulty or damaged, the entire DDM unit must be replaced.
