Double failure of 4-wheel drive indicators. 4-wheel drive failed but the "service light" did not appear on the dash and the LED light on the 2wd/awd/4-hi/4-lo switch did not display correctly. Because we were unaware that both indicators were not working and the 4-wheel drive was not working we attempted to go over a mountain pass during snow conditions under the assumption that the 4-wheel drive was working correctly. I was bringing my mother home from the hospital after a heart procedure. Luckily I was driving carefully, because the vehicle did begin to lose control, but I was able to make the necessary corrections. We were forced to turn around and take another route, which doubled the length of our drive. This normally would not be a problem except for my mother's condition.
2003 Chevrolet Trailblazer EXT electrical complaints

As I am going down the road the tachometer starts to jump around and then I lose the directionals and my lights. If I turn off the ignition it will not start again. This has happened four times in the past year. The dealership tells me that fuse #22 is blowing. As of today, my truck is still at the dealership and they do not know what is causing it. They have replaced the fuse each time. They also replaced the instument cluster and the ignition lock. I am seeking legal advise.
Have had my 2003 trailblazer lt 2wd v8 in the shop under warranty many times. First was a recall on the drive shaft which was replaced 3 times. Still have a noise the dealed says they don't hear! Next came the taillight recall. Now I have a recurring problem with a dead battery. This doesn't happen all the time and nothing has been left on to cause it. I can go into a store and come out to find it dead. When you charge the battery, then either the heated seats work improperly, the blower won't come on, something different every time.
Went out to start vehicle on september 18, 2004 - tuned key and nothing happened, no starter motor, no dashboard lights, nothing. Key remianed locked in steering column, could not be removed. Tried again the next morning (9/19) - same thing. Tried again the next morning (monday, 9/20). The same thing - at that point called dealer to tow vehicle. About 3 hours later the tow truck came - tow truck operator got in vehicle turned key - and vehicle started right up just as if nothing was ever wrong! . Still had vehicle towed to dealership - dealer checked behicle over and found nothing wrong. On saturday, october 23rd, came out of bank after running errnad, turned key in vehicle - nothing happened again. Kept turning key off and on for about 10 minutes until vehicle started out of the blue. Drove straight to dealer. Dealer replaced ignition switch. Vehicle worked fine until sunday, january 23rd. Went to start vehicle and one again, nothing happened, no lights, no starter - nothing. Key also locked in steering column. Dealer towed vehicle the next day. Dealer could find nothing wrong, theorized an interior light was left on (but I know it wasn't). Dealer replaced some engine fan they theorize was turning on after engine turned off and draining battery - I told them that's fine but doesn't explain why truck will start days after an initial failure. This intermittent failure is frightening as it seems to be a possible part of a larger system failure - as noted on this website by other owners - when the trailblazer will fail at high speeds on the highway. (reference odi id numbers 10101741 & 10060860).
Vehicle shut down while driving on the freeway, ignition locked. Consumer shook the steering column and it started. There was a multiple vehicle collision since the vehicle shut down at 65 MPH.
Front end loose, ball joints needed replacement. Driver side seatbelt defective/twisted. Rotors warped needed repalcement. Outside door handle does not open door. Dirver side mirror moves around (programed) without notice. Transmission engages rough, feels like it slipping. Tailgate out of allignment, rear seatbelt defective needed replacement, 4wd locked up in parking lot, front end has scraping noises when turning, heated seats not working, irratic, tailgate panel falls off, driver seat frame broken needed replacement,electrical system irratic.
Complete power failure while driving vehicle in traffic on interstate. Cruising up the interstate at 65-70 MPH and vehicle dash went black, steering locked, coasted to roadside and tried to restart vehicle. It took 5 attempts before vehicle would restart. This happened twice more the same day. Dealership had vehicle for 5 days and stated they were "unable to duplicate customers concern", but reprogrammed the PCM anyway.
