Question about Chevrolet TrailBlazer EXT
To begin with, likely you could have just re-charged the battery using an external charger and been done with it, unless the battery was very old and ready for replacement. OK, so you replaced it....Highly probable that the computer lost it's memory and needs to run through a complete drive cycle in order to regain it's operating parameters. Usually you can do that without having it "flashed" at the dealer by simply taking it for a long (over twenty five mile) drive. Usually that is sufficient for the computer to run through a complete cycle and re-set itself. If not, You may end up at the dealer (sorry) for a re-calibration.
It won't hurt to have a code scan done first, most larger parts outlets do that free...I'd also make sure no fuses are blown in the power distribution center under the hood.
