I got a 98 voyager and the rear wiper and a/c buttons are flashing...I disconnected the battery for a night and hooked it up and it still does it. I heard there is a way to "program" the control panel? Need help thanks

Try one of these. Make sure the A/C is working first or the lights could flash till it's fixed: http://www.allpar.com/fix/codes-climate.html

This happened to me once. My system was out of calibration. Here is the solution.. I hope

CALIBRATION/DIAGNOSTICS TEST ENTRY
TO INITIATE TESTS:

* Set Blower motor ON HIGH
* Set Mode position to Panel
* Open all A/C outlets
* Set Temperature to Cold (Both slide pots if equipped)
* Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light)

RESULTS:

* All LED's will turn on for 5 Seconds
* Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cool-down test is running if A/C and RECIRC are alternately flashing.
* Acceptable result is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.

Good Luck
