Stop by your local public library (or Canadian Tire store, or Walmart auto dept) and look for a Haynes or a Chilton manual for your model.

It's basically an illustrated take apart and rebuild manual, for about $20 CDN.

How do I change the heater core in a 2002 chevy trailblazer?

heater core in trailblazer is a very complicated procedure. It involves disabling the air bag system and removing the entire dash (actually tilting it back against seat) to access the heater core box. It also involves removing some parts under the hood to release it from the firewall.

Check for vacuum leak under dash to heater control vacuum harness, or anything connected to it. Commonly disturbed by stereo installation Could also cause a rough idle. Leak could also be found between manifold and vacuum junction to heater control under hood.
