Damn near got killed! As I was driving, my cabin filled up with so much smoke, I couldn't see. Chevy customer service said there was no problem! (maybe because no-one died) Had the problem repaired at a local shop for $364.00.
The early signs of failure are the loss of fan speeds or none at all. Failure usually occurs under high heat and/or AC usage. I had to replace the heater fan ballast controller unit and the burned out connector harness. The cheap OEM one fails from corrosion and overheating. The aftermarket ones are more reliable, cheaper and comes with the replacement harness. (Advance/Autozone/NAPA/etc)
Good luck chasing GM (government motors) for re-reimbursement. I filed twice within the past year and reported to the NHTSA.
