2007 Hummer H3 wipers, windshield & visibility problems

I was in a parking lot, I started the vehicle and turned the air conditioner on. It worked but suddenly stopped blowing air. I took it in and it was diagnosed as the blower motor resistor had gone out. I had it replaced only to have the same thing happen again one week later but this time I smelled something burning. The wiring had burned going to the resistor. The technician informed me that this happens often with these vehicles and he doesn't understand why there isn't a recall.

Tl* the contact owns a 2007 hummer h3. While driving at an unknown speed, the air conditioner failed to blow air out of the vents. The vehicle was taken to the dealer. The technician diagnosed that the resistor needed to be replaced. While inspecting the vehicle, the technician noticed that the resistor was completely melted. The failure recurred twice after the initial repairs were completed.
