The most common problem that will cause this is when the control loses vacum going to it then it will default to blowing out on the windshield.You need to check for a vacum line under the hood that has come off. This vacum line will run through the firewall to the inside ac control panel

Perform a calibration attempt on the head to try to reset it.


  • Set Blower motor ON HIGH

  • Set Mode position to Panel

  • 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.
