OEM radio /domes working upon exterior unlock.
I replaced my aftermarket radio in my other GM product both are less than a year apart w factory unit. Both my wife blazer and Yukon both showed class 2 com error. Yukon now domes work w key unlocking doors, wifes blazer says same code. Class 2 com error, does anyone know if the that part of the dome wired through OEM radio? I did look prior to asking this.
