Code B2208 Buick Description

The driver or passenger door switch signal circuits provide inputs to the Driver Door Module (DDM) or Passenger Door Module (PDM) when a window switch is activated to the UP or DOWN position. These inputs allow the door module to detect a window UP or DOWN request. The door modules provide power and ground to the window switches. When a window switch is activated to the UP or DOWN position, ground is supplied through the window switch to the signal circuit, which is pulled low. When the door module detects low voltage on the signal circuit, it will command the window in the UP or DOWN direction. When the switch is released, the command ceases. The door modules monitor the signal circuits to determine how long the ground has been applied. If the door module detects that a ground is applied for greater than 20 seconds, a Diagnostic Trouble Code (DTC) is set.
