Windows program or Android app to read GM body codes?

[aczlan]

Looking for an inexpensive app or program that will talk to an ELM327 code reader and read GM bodycodes, specifically, the codes for the rear HVAC system on a 2005 Suburban.
Anyone have anything that has worked for them?

You are probably going to be out of luck. Most inexpensive readers (sub $1k) will read just engine codes. Mfgs are not required to use generic codes when it comes to other computer systems. Because of this they charge scanner companies quite a bit if they want the information. Toyota has their own program (techstream) that can be found for free on the internet, maybe GM has something similar.
