Hi everyone!

I just recently replaced a dead battery on my S2000. Then, after it was replaced, the climate control is all of whack. The driver

 

Perhaps some other action was taken. In my 6+ years of ownership, I have had two battery replacements, both by the same tire& battery dealer. Both times, the only problem has been the obvious need to reprogram the radio - nothing else. If done by a service dealer, might they have touched something else under the hood, knocked off a hose, perhaps? I would perform a careful underhood inspection, looking for something which is loose, hanging, disconnected......

 

Maybe check your vacuum hoses

 

I'd be surprised if the dead battery caused this problem.
