Four problems related to alternator/generator/regulator have been reported for the 2002 Chevrolet Trailblazer. The most recently reported issues are listed below.
My headlights started to flicker one seasonably winter day. I had the heater motor replaced 2 months prior to this incident and back wiper motor just a month before this. Then the heater motor cut out, and did so numerous times as I traveled on a 20 degree day. It seemed to run fine after that for the most part that day. I later got into it and again headlights flickered and heater motor cut out. Especially when I would accelerate or turn to the right. I replaced the battery, alternator and had ground wires cleaned only to have it recur a week later. I do most of my driving at night and when the lights went out and came back on I had had enough. This had become quite costly and my mechanic was at a loss as to what to do next. I took it to a chevy dealer and traded it in on another vehicle, as I can no longer afford to keep spending money on a mystery issue.
I bought a 2002 chev. Trailblazer ltz from joe cecconis dealership. My alternator was bad they told me when I bought it and so they replaced it in 2008. Wed. Nov. 18th 2010 it caught on fire while I was in it. The local fire dept. Made a report and joe cecconis wont return my calls. What do I do?.
Both rear window regulators went out at the same time not from wear hardly used them makes to much noise. Four wheel drive differential locking hub locked in won't come out. Electrical problems with radio, dash lights, heated seats just to name a few. Idle not right stalls out while in park sometimes. Nothing fixed yet have to save money because cost to much to go to dealer,it costs a 100. 00 just to have them hook up to machine and then it says nothing is wrong but all this is wrong ,it does not compute.
