I have a 2003 Chevy Trailblazer LT and a few months back the rear HVAC blower motor started running all the time. It would not turn off and continued to run even with the ignition key removed. I removed the fuse from the rear fuse box to stop it and everything was fine except for the rear air, of course. Summer is coming on strong here in South Alabama and I need help with this. Any Takers? Thanks
