Hi all: 2015 Mazda 6 touring had the serpentine belt fail, caused the front body control module (computer) to malfunction and the heater blower motor not to work. Shop replaced the body control module and blower working again. A few weeks later noticed passenger HID light not working. Not sure if it was working or not before module replacement. In the shop again, (local non-branded shop because 80 miles to the mazda dealer) they thought it might be the body control module so replaced that again ($300) but did not fix the light. Relays and fuses all good. New bulb in the light. They can't find the problem. Light for sure was working before serpentine belt failure. Any help appreciated.
