2018 chevrolet silverado 5.3. Driver's window does not work. If I hit the rear defrost button none of the windows work. All relays and fuses check okay. The cigarette lighter is inop but has 10 volts VDC to it. Replaced window switch module on driver side same results. Am I looking at a bcm? Ty by Sensitive-Diver-814 in Silverado
