HVAC parts interchangeable between 03-06 TB or Envoy?

[JayWildChevy]

So, I am looking at purchasing a blower motor for my '06 Trailblazer.

One of the junk yards has a motor available from 2002 and 2003 Chevy trailblazers, and a blower motor from a 2005 GMC Envoy.

Could I use any of these to replace my blower motor?

Here are the part numbers.

The motors should be fully interchangeable. Those are stock numbers which make me think that's just telling them that they have it or where it's at. I don't think that is a part number because I doubt that GM changed the blower design every year like that says IF that was part numbers.

Thanks so much!
