Problems with 2008 Chevrolet TrailBlazer ELECTRICAL SYSTEM

My fan blower quit working on some settings (0-5 available, only 1,2, and 3 make fan work). i bought a new blower resistor to replace it, and when i tried to disconnect the old one, i discovered what appeared to be an electrical fire had fused the harness to the resistor. i was able to break the harness away from the resistor, but two of the connectors on the harness are blackened, and the harness is partially melted away. when i hooked up the new resistor, 1,2,3, and 5 work, but 4 is still not operational. i believe 4 is not operational due to charring or melted plastic preventing connection from being made to one or both of the two charred connectors. first date of problem is estimated to be winter 2012, though it may have been a year or two earlier. my replacement of the resistor was 18 oct 2014. *tr

I bought this vehicle back in september 2009. ever since i bought the vehicle i have had problems with the traction control lights coming on for no apparent reason. this happens when its hot and cold, dry or wet. just starting the engine makes then come on. i have been back to the dealer for 2 years now for the same problem and they tell me that they don't know why it is happening and can't fix it. my vehicle is now out of warranty and will never be fixed. ?*tr

I was driving down a state highway with my cruise control set at 57 mph and all of the sudden all of the lights came on in the console. my on star did not work, nor did the radio or anything electrical in my vehicle. my vehicle was still running, but none of the gauges, lights, windows, etc. were working. i pulled to the side of the road and then drove it to the dealership. the dealership kept the vehicle for 3 weeks and were not able to diagnose nor fix the problem. all of the sudden 3 weeks later they got into the vehicle and the problem had resolved itself.

While entering a gas station the vehicle in front of me slammed on the brakes. this was done because the gm at the pump had it's backup lights on and wasn't even backing up. what's really disturbing is the fact people will start ta ignore these in dark or rainy parking lots and potentially get run over. shouldn't backup lights only be used for backing up? this looks like a problem with the whole vehicle lineup. *tr

I bought this 08 chevy trailblazer new 9-30-08.from the date i bought it i noticed the charging hand on the instrument panel shows the battery not charging about 50% of the time,the owners manual says this is a fuel saving feature .when the battery is fully charged the alternator quits charging.after approximately 1 month of driving this veh.i noticed when it quit fully charging the power windows would not roll but 1/3rd of the way up,the veh.can't be driven in the rain due to the wipers barely moving,the bose stereo system loses power and malfunctions,and im sure other things don't function properly,the transmission malfunctions and wont shift like it is designed to do,the miles per gallon gauge resets itself while the veh.is moving. i have had the veh.to the local chevy dealer and they don't have a clue to why it is doing this,i think if your driving on a major highway and run into a hard rainstorm you would be lucky to get off the highway before causing a major accident due to the wipers not working properly,,i experienced the situation once but was lucky traffic was light. am taking the veh.to another dealer this week to see if they can fix the problem. the wipers not working properly is an extremely dangerous problem. *tr

We purchased a 2008 chevrolet trailblazer in september 2008. the day we drove it home the entire electrical system shut down. the lights, locks, blinkers, and all gauges were not working. the vehicle was taken back to the chevrolet dealer and the onstar module was replaced. a few months later the electrical system failed again, this has happened 3 more times since purchasing the vehicle 3 years ago. the vehicle has also had the check engine and stabilitrack lights turn on and off numerous times...sometimes for a day or two, sometimes for a week. the vehicle has been in the shop more than 13 times in 3 years for electrical related problems, several electrical modules have been replaced. my grandmother has the same vehicle and has had the same type of problems with the electrical system. *tt
