My AC controls are stuck on 71 degrees with automatic fan control. I can no longer alter the temp up or down or have manual control over the fan speed. The light for "auto" is not on, but the AC seems to be stuck in the automatic mode. Pushing any other controls will not change this (and the "on" lights do not come on for the other controls.) This is a "new to me car" and does not have an owner's manual. I have not yet ordered one. The AC did previously work. Have I done something? Is there anything I can do to change this setting?

I solved the problem. Can't begin to tell what combination of button pushing got the system "unstuck" but something worked. Does anyone have a link to a good place to order an owner's manual for this car?
