Check a wiring diagram an check power an ground for those systems . Also read factory service information on how they work . Electronic modules involved . DDM - driver door module . If this vehicle came to my shop , first thing I do , hook up factory scan tool an check input data from the door switch to the DDM . Check DTC'S - diagnostic trouble codes . The power windows system consists of the following components: • Driver door module (DDM) -- GMLAN device that receives and transmits messages and signals for window functionality • Passenger front door module (PDM) -- GMLAN device that receives and transmits messages and signals for window functionality • Left rear door module (LRDM) -- GMLAN device that receives and transmits messages and signals for window functionality • Right rear door module (RRDM) -- GMLAN device that receives and transmits messages and signals for window functionality • Driver door switch assembly (DDSA) -- GMLAN device that contains the driver, front passenger, RR and LR window and window lockout switches • Right front power window switch -- provides switched ground window switch signals to the PDM for the front passenger window • Left rear power window switch -- provides switched ground window switch signals to the LRDM for the left rear passenger window • Right rear power window switch -- provides switched ground window switch signals to the RRDM for the right rear passenger window • Left front power window motor -- contains position sensors and a module that receives signals from the DDM and provides a status signal to the DDM • Right front power window motor -- contains position sensors and a module that receives signals from the PDM and provides a status signal to the PDM • Left rear power window motor -- contains position sensors and a module that receives signals from the LRDM and provides a status signal to the LRDM • Right rear power window motor -- contains position sensors and a module that receives signals from the RRDM and provides a status signal to the RRDM • DRIVER DR MOD fuse (10-amp) • FRT PASS DR MOD fuse (15-amp) • REAR DR MOD fuse (10 amp) • Power Window Motors Circuit Breaker (30-amp)
