I'll be selling my trailblazer soon. It's a great vehicle I have loved it but I'm not wanting to invest anymore time and effort into it. It is beginning to have problems with wiring,I think,because the brake lights and parking lights are confused the turn signals work when they want to which is rarely. It has the 4.2 which I like but throttle response is getting sluggish and I don't want to bother with it. I'll be posting photos soon if anyone is interested.
