GM module controls some of those functions... before considering the GM fried, maybe something else can be done...

also, it feels that you might have a hall sensor in the driver's door malfunctioning - or, some other circuit in the driver's door... some of the symptoms support that theory... was there anything done to the driver's door, any recent work, any impact, maybe you noticed something prior to this epic failure?

i can't open the WDS diagrams at work to see the details, only once i am home...

maybe meanwhile somebody else can look into the issue...
