I think I am having some electrical issues

[H2duramax]

Ok so for the last couple days my 2008 h2 has been having some issues, the recycled air light flashes on and off while driving down the road and the flow from the a/c seems to surge as well. Today I have had a new problem with the factory stereo, my wife and I drove to an appointment downtown with no problems, but when we left the radio would not play. The unit had power and went through the motions but it was like there was no connection to the speakers. It tried am/fm, xm, cd, and the DVD player. No sound at all. Powered it on and off several times on the hour drive home and no change. I went out to the truck a little while after I got home and now it plays fine.
So what do y'all think? Anyone else had anything like these happen?
