your blend door actuator is hanging up, take the battery off again for 20 minutes or so, then hook it back up, some times they will straighten them selves out.

after you hook the bat back up, sit in the car and just turn the key to run let the dash light up and ding, hit auto on the climate control, with any luck it will be normal again.

i only suggest this trick because it worked fine before you changed the battery is my guess.

if this happens with out touching the battery most of the time the blend door actuator is bad.

the pass side is easy to get to at least, if this dont fix it, you can take the glove box off/out of the dash, and right on your left side you will see it, so you can unbolt it and turn the knob by hand to cold or heat.
