2005 Chevy Trailblazer Check Engine and ABS lights are on

Hello, My check engine light and now my ABS light in my truck won't go off. They've been on for months. I got a tune up last November and the engine light went a away for a few days, but has been on ever since. Also, I had my truck in 4 Wheel Drive for a little while a few weeks ago one day when it snowed really bad and ever since it seems like my car sounds louder when I drive.

2003 GMC ENVOY A/C only blowing cold on drivers side

I just bought a 2003 GMC ENVOY SLT w/ the 4.2L 6 cylinder.  I am having trouble w/ the A/C it will blow nice and cold on the drivers side but the passenger side and rear are blowing HOT air. I have been on quite a few forums and there are tons of people having this problem but nobody seems to have the answer. So if someone could help me out I would greatly appreciate it.
