98 Ply Voyager - flashing cluster lights

Ever since I installed a new battery, the rear window cluster lights keep flashing. The rear wiper switch, intermittent rear wiper, rear window defroster, & recirculation control keep flashing. Everything works but how do I stop the flashing?

You need to recalibrate the system CALIBRATION/DIAGNOSTICS TEST ENTRY TO INITIATE TESTS: a.. Set Blower motor ON HIGH b.. Set Mode position to Panel c.. Open all A/C outlets d.. Set Temperature to Cold (Both slide pots if equipped) e.. Depress WASH and REAR WIPER button simultaneously for 5 Seconds (Until all LED's light) RESULTS: a.. All LED's will turn on for 5 Seconds b.. Calibration Test is running when REAR WIPER and INTERMITTENT are alternately flashing. Cooldown test is running if A/C and RECIRC are alternately flashing. c.. Acceptable results is REAR WIPER LED is the only LED flashing. Push Rear Wiper to exit. d.. After all tests have passed, Calibration Diagnostics and Cooldown can be run separately. COOLDOWN TEST ENTRY TO INITIATE TESTS: a.. Set Blower motor ON HIGH b.. Set Mode position to Panel c.. Open all A/C outlets d.. Set Temperature to Cold (Both slide pots if equipped) e.. Depress WASH and A/C simultaneously for 5 Seconds NOTE: Prior to start of test, If the evaporator is already cold, the system will fail test. To correct, operate system with A/C OFF and the blower motor ON high for three minutes prior to starting test.

RESULTS: a.. All LED's will turn on for 5 Seconds b.. Cooldown Test is running when A/C and RECIRC. are alternately flashing. If A/C and RECIRC. are flashing simultaneously, Cooldown has failed. CALIBRATION DIAGNOSTICS AND COOLDOWN ABORT Test can be aborted by doing one of the following:

a.. Depressing Rear Window Defogger, RECIRC and Rear Wiper buttons. b.. Cycling Ignition OFF and then ON. c.. Control will automatically abort after 15 minutes from the time Calibration Diagnostics and Cooldown was entered. The HVAC control module will return to normal operation or may indicate unsuccessful Calibration Diagnostics or Cooldown test by LED's flashing simultaneously.

EEPROM DATA Calibration Diagnostics, Cooldown Status and evaporator temperature Fin Sensor values are stored in an EEPROM memory internal to the control. The microcomputer within the HVAC control module uses this information:

a.. To determine if Cooldown needs to run b.. For proper position of the Heater-A/C unit assembly doors ACTUATOR CALIBRATION AND DIAGNOSTICS

Actuator end point calibration takes approximately 60 seconds. The REAR WIPER and INTERMITTENT LED's will flash alternately during the test. The control will cycle the Blend actuator(s) to the Heat stop first then back to Cold. After the Blend actuator(s) have been calibrated the Mode actuator will be cycled to Defrost and then to Panel. Successful calibration is defined as actuator travel falling within their minimum and maximum limits.
