Question about Chevrolet TrailBlazer
Sounds like your starter solenoid is wearing out. Inside the solenoid, there's a copper disk that comes in contact with two copper posts when the solenoid activates, completing the starting circuit. When the posts arc out, or the disk arcs out enough, then it will intermittenly start just as you describe. It's more noticeable when it's cold, because the copper has contracted just slightly. You'll still get the click from the solenoid, but the starter won't catch. If you're mechanically inclined, you can take the starter off, take the back of the solenoid off, and pull out the mentioned parts for inspection. If the disk is the problem, then you should be able to flip it over for use for another 100,000 miles or so. If it's the posts, then find an auto electric store that rebuilds starters, and they're usually happy to sell you a couple of posts for $10 or less. This is a fairly common issue, not just with GM, but with almost all car manufacturers; honda, chrysler, toyota, mazda, ford, etc. It's a part that wears rapidly due to the high current draw, and the fact that it arcs every time it's started.

Sounds like the starter is going. next time (if possible) that it just clicks.... have someone hit the starter with a hammer. not hard enough to break it but hard. if it starts up it's time to change the alternator. you may also want to replace the starter relay. it's located in the fuse panel inside the engine compartment near the battery.

The battery light on the dash indicated that the alternator/ charging system of the battery is not okay.
This is not a generic problem to General Motors therefore will not make a recall.
It is the alternator that you should be looking at replacing at this time. Since you have a new battery.
Good luck and thanks for using Fixya.
