Chrysler Repair: 98 Plymouth GrVoyager Rear Wiper Blinking, slide pots, calibration test

Question
My 98 GrVoyager's RearWiper/Intermittent Lights are blinking...for a while then they go off.  I recently changed my battery, thats when they started doing it but continued after the new one.  The Recir/AC lights do not come on during the blinking of the other lights but they do work.  Help me please.

Answer
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. Cooldown test is running if A/C and RECIRC are alternately flashing.
Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit.
After all tests have passed, Calibration Diagnostics and Cooldown can be run separately.
COOLDOWN TEST ENTRY
