Case Details: The technician connected a scan tool and found no diagnostic trouble codes (DTCs) from any of the modules.

An ALLDATA Tech-Assist consultant recommended checking the master window switch's 12-volt power supply and ground, which was also shared by all the other window switches.

 


    Confirmed Repair: The technician found a bad ground connection at the master window switch terminal 17 (BLK). He repaired the connection. Normal power window functions were restored. Problem solved!
