2004 Chevy silverado with digital duel climate control the passenger side only blows very hot air no matter what the temperature setting Is there any way to reset this Thanks?

I am having simalar problem. So far I have removed the hvac fuses under the hood and in driver side fuse panel (between door and dash). Leave them out for 10 minutes. Reinstall fuses and start truck up. Place climate control in AUTO. Unit will cycle through vents in calibrate mode. I have had limited succes so far doing this. I the begining I have hot on both sides, then passanger, then driver side. I seems to change when I shut the control down with the power off butten on bottom left side. Now both sides are responding to temp control changes, but supply temp does not seem to match setting. It seems that temp is not calibrated properly. It appears to be 5-10 degrees higher that actual. I think I am on to the right track, but missing a step somewhere. Hope this can help you in some way.

NOTE: My issues started the same time I changed the Battery in the truck. It must have done somthing to the programing in the modual.
