“One day when I went to turn on the air conditioner, the AC wouldn't come on. When I turned the control knob to 4, I could hear a clicking under the glove box. On certain days the blower motor would work and sometimes it would quit randomly while operating. Upon inspection I discovered the blower motor resistor had become hot and melted to the connector causing char to build up inside the connection.”

NHTSA complaint #10652948, filed 2014-11, 120,000 miles

I have contacted general motors about this issue and they have not been very helpful in resolving this problem. They are telling me since I have had the recall completed which really wasn't there is nothing they can do for me. Back ground history is the items first failed in 2013 and I paid to have them replaced. The recall came out and they counted the previous repair as the fix. …”

“While driving on a hot day I noticed an odor of smoldering wire coming thru the blower vents. I pulled over on the highway and checked under the hood. I noticed the blower motor was hot and melting.fortunately there was only smoke and no fire. I turned off the A/C blower (which was now not working) and took it to my local A/C repair station for an estimate. The vehicle was past warranty so the repair station replaced the melted blower motor, resistor and harness using genuine GM parts. This is the first incident and pertains to GM recall #15042, nthsa campaign id 15v421. …”
