One problem related to air conditioner has been reported for the 2005 Chevrolet Trailblazer. The most recently reported issues are listed below.
Turned vehicle on and found a/c blower not working and abs and brake light come on. Blower will come on intermittently when the bas / brake light goes out. I am concerned that if there is a short in the system there could be a fire. Chevrolet should be taking care of this concern for the owners.
