Chrysler Repair: Flashing a/c and recirculation lights98 minivan, grand voyager, acceptable result

Question
Ever since we replaced the battery in our 1998 Grand Voyager van, the a/c and recirculation lights flash constantly.  What can we do to fix this?

Answer
Hi Roger,
The calibration/cooldown tests needs to be done: Start the engine,
Set blower on HIGH
Set mode on PANEL
Open all A/C outlets
Set the temperature to Cold
Depress the WASH and REAR Wiper Buttons simultaneously for 5 seconds
The unit will go thru several steps during which the rear wiper and intermittent will be alternatively flashing, and then the A/C and RECIRC will alternatively flash
Acceptable result is rear wiper only flashing. Push rear wiper to exit.
If some other result appears, then some remediation is needed.
