Hello,

Ok, first you may want to double check the year. The TrailBlazer didn't come out till 2002.

Here are some possibilities.

Here is a quick way to diagnose cranking problems is to switch on the headlights and watch what happens when you attempt to start the engine. If the headlights go out, a poor battery cable connection may be strangling the flow of amps.

Bad Battery - Just because all your other electronics work doesn't mean the battery isn't bad. Your starter needs CCA (Cold Cranking Amps) and if they low or don't exist then your vehicle wont start. Try Jump starting.

Bad Ground Wire or Wires - Check Battery Negative make sure clean and tight at terminal and at block. Also check the Braided Steel Grounds. Locations can very. Some are from hood to firewall then to engine or frame, some are from frame to engine.

Battery Corrossion - Check Battery Positive for corrossion at battery and at starter. Also make sure connections are tight.
