B1262 = defrost door servo - If you can change the airflow to get it out the defrost vents and then change it to the dash vents, it's working and just may have been momentarily stuck. It seems to be common to see stored codes for various servo motors when there is no real problem.
B2799 = Passenger Coolant Control Valve Open Circuit - Your DCCV is starting to fail, or has failed. When failed, you will get heat (full heat usually), but you won't be able to get cool air (after the engine has warmed up). It's possible that it's only a minor issue that doesn't alter operation yet. I've seen this code on my 04 every now and then for a few years and it's still okay. (I do know that eventually it will fail.)
Thanks joegr--Oh it's failed. The a/c hasn't worked since it crapped out. I have full heat coming out of both sides-it was working fine before. Is the dccv something that I can do myself or do I have to take it somewhere to get it done? I'm ok with small mechanical jobs and pretty handy.

Search this forum for DCCV. It's not a five minute job, but it's not too hard either. Be sure to correctly bleed the system after replacing the valve. Also, don't get a used or aftermarket valve.
Thanks will do- I tried to seacha few things but there is so much information!

I posted this in a different thread, which was probably the wrong place, but...
Hey guys,
So I sold my '02 V8 and found a really nice '06 V8.
I just put my radio in from my old LS into my new LS. After putting everything back in the dash, my AC is not working at all; it's blowing hot air out of all the vents, no matter what temperature I put it on. The AC was working just fine earlier today before the install, as it's finally warming up here in NC. Did I ground something out? Any fuse I can check? I'm really stumped on this one...
EDIT: Self test showing:
12 64
12 62
27 98
EDIT2:
While running another self-test, I noticed some very light static coming from the drivers front speaker..
