Chrysler Repair: Town&Country Blinking console lights, slide pots, calibration test

Question
This is a follow up question to another blinking light question. I have a '97 T&C with the following 6 lights blinking: all 3 wiper lights, A/AC, Defogger, circulating Air. I believe it was caused by a power converter I use to plug things for the kids on long trips. I plugged the converter to the rear outlet. The Van would power off during a stop, after we got home thanks God. I disconnected the converter and test drove the Van. Everything works fine but the light continue to blink. Hoping to keep this Van a few more years.

Thank you for any suggestions.

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
