One by one things have been going out and not working. First the car would not start all the time with the key, then the A/C stoped working, next was the fuel pump, then the injectors. I checked everything it could be. I was driving with my kids down the highway when my car just died lost power steering so it was hard to get off the road fast. I got it started and was driving and it did it again. I was able to finally get it home when it would not start again. After some research online found out this car has issues with the fuse box itself under the hood. I opened it up just to find the wording that connected the pins was broken in numerous places and had started to burn up in the box.

5 months after I purchased my 2003 chevy trailblazer I went out to start the car and it would not start. I took the car to the dealer the first time for this problem and various others and was told they could not replicate the problem. I replaced the battery and the car worked for approximately another 5 months and the same occurred. On both occasions the key was locked in the ignition and attempts at jump starting the vehicle failed multiple times. Since the second time happened this morning I have yet to take it to the dealer. This car also has various other electrical problems sometimes the radio goes blank and gets stuck on one station as well as getting extremely hot (was told they could not replicate all of the problems but reprogrammed the radio so it would not get as hot). The dvd player just stops working (was told they could not replicate the problem). The blower motor for the rear air works sometimes and other times it doesn't (this was apparently fixed once already). The reverse lights stay on when the car is in drive (just happened last weekend). Shall I go on?

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.

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).
