I bought my 2017 Chevy Silverado Custom DC 4.3 brand new since then my window washer stoped working, apple car play will not work, reverse lights stay on all the time recently my battery goes dead overnight. I’ve had the battery replaced and checked alt checked fuses and relays checked grounds checked. Now my hvac blower doesn’t work my my link radio won’t come on passenger windows will not roll up or down locks don’t lock or unlock by button or fab. I have had a compustar alarm and remote start installed two years ago and an amplifier and subwoofer. I have only had the problems recently. I have unhooked the alarm and amplifier with problems still exist. Truck has 82000 miles.
