The Product & Service Solutions (PSS) armored vehicle window control modules are intended for use in armored and protective service vehicle applications when alternate window motors are required. The PSS modules are designed to allow alternate window motors to be used in place of the production driver and passenger front 7 pin window lift motors in 2015-2020 model year and 2021-2023 model year GM full size SUV’s including the Suburban, Yukon XL, Tahoe, Yukon and Escalade. Because these window lift motors are a “smart” module that communicates with the vehicle you cannot simply remove the motor and install a new motor. Doing so will cause diagnostic error messages to appear on the driver information display, loss of door closed information to vehicle systems and requires using non-factory window switches.

In order for the system to function properly a driver and a front passenger side window control module must be used in all GM full size SUVs, even if you do not plan to have all windows functioning. The PSS modules are compatible with the OEM rear motors (you do not need to change the rear motors or any window switches).

The PSS window control modules provide the following features and functions:

  • Plug into the factory window control harness and connector.
  • Retain the factory window switches.
  • Control window position at the door into which it is installed via the GM factory push button switch.
  • Driver side GM factory window switch retains control of driver, passenger front and passenger rear windows (when present).
  • Allow alternate window motors to be used without causing error lights or messages to appear on the driver information center (DIC)
  • Monitor and report door open/closed position
  • Splash resistant sealed enclosure
