Dual Zone Climate Control Issues

07-22-2009, 06:55 AM
Hello. Replaced the battery in my 03 H2 and now the passenger side is blowing out 90degree air. Everything worked good prior to this one event. I have found this problem noted on several 'ask the mechanic' sites but no one seems to know why it happens (any of the DZ issues) or how to actually resolve it. SO, I am where I should have started.. here... ANY help is appreciated. Thanks
