AC Electrical issue

I changed the battery in my 97 caravan and now the ac doesn't blow cold and the lights on the controls are flashing.

This happenned before and the dealer said they had to program the ac contol head.

Need help.

Scroll down and look at my response to the post "wierd blinking lights" on 6-19-06. The procedure listed there is for 1998, but it may be the same for 1997.

Usually, the AC still blows cold when the lights are blinking, but do the recalibration and see if everything works afterwards.

Yep. I found it on another forum. That did the trick. Thanks for the reply.
