Google it. You have to take glove box out to get to it.
Here is my post, including part used. By the way, same issue happens with Hummer that shares parts.
Easy fix at Part Source for resistor and harness kit. I have part number listed below. Don't get the OEM. You have to pull wires out and reset with connectors. The Dorman part just had to crimp wires. Easy-peasy!
I too just experienced same thing. Could feel cold come out of vent, but no blower!
Took dash apart, pulled harness, and found the exact same connector burnt!
Went to GM dealership in Burlington, they had the red piece of harness, and five clips, plus resistor for $91 plus tax. I didn't want to be pulling old ends out, or cutting and getting shorter leads, so passed and went to Part Source in Burlington to see what they had. For $86 plus tax, it was the red end of the harness including about 8" of wiring intact, and 5 wire connectors plus the resistor. I liked that I had the extra wiring so not straining to reconnect with shortened wires.
For anyone looking, they have a Dorman Products Blower Motor Resistor kit. Product sku is 973-510. Took me half an hour to fix harness, and plug in. Fingers crossed, turned the key, and hit the AC and it was ALIVE! Now I can drive again in this 30 degree plus humidex for a feeling of 40 degrees Celsius weather with my roof up!
