“Wench holding spare tire on 2002 chevy trailblazer was stuck and would not lower the tire. Having a flat tire is bad enough but being told that they would have to cut and destroy the wench mechanism in order get the spare to put it on in place of the flat one was not good news. I told aaa to proceed and cut the cable and mechanism so they could change my flat tire. I found this is not under warranty and it cost $137.00 to replace the wench. This happened in august 2006/ in october, my wife had a flat and guess what the wench would not lower the spare and again the mechanism had to be replaced. …”
