1998 Plymouth Voyager Flashing lights

The flashing lights indicate your Environment Control Computer needs calibrating. Here's how:
With engine running.
Turn blower motor to high
Set mode position to dashboard vents only
Open all the vents
Set the temperature to cold (both slide pots if equipped)
Depress wash and rear wiper 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 when A/C and RECIRC are alternately flashing.
Acceptable result is REAR WIPER LED is the only LED flashing. Push REAR WIPER to exit.
