Report: AC Blower Inop Due to Failed Resistor
Chevrolet Trailblazer Problem
Average Mileage: 84,190 mi (10,500 mi - 150,000 mi)
The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.
Blower does not work at level 5. Only runs on levels 1 - 4. Replaced blower resistor and that solved the problem.

my a/c blower does not go off even when my key is out of the ignition. the temperature gauge goes from 80 degrees all the way down to 10 degrees and back up again intermittently. Now my a/c says it's on full blast but nothing is coming out of the blower at all.

Speeds 1-4 work, #5 quit today, nothing at all. After reading reviews and some internet searches on different sites, I've narrowed the problem down to a faulty resistor and purchased one online through Amazon. I'll let you know if this is successful as with others to remedy the problem.
