Answer
Hi Brian,

     It would help to know what the display is doing. And can I assume that everything worked before the battery was changed?

    When the battery cables are disconnected or reconnected the ignition key needs to be in the off position of sometimes things like this can happen or computor damage can occur. What you can try is to disconnect the battery negative cable with the key off for 10 minuits and then reconnect it and see what happens. Maybe things will return to normal.

    If you need more help let me know what the displays are doing and check all the fuses for being ok especially for the blower motor. Bill
