    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.
