Information & Bulletins
Due to the unavailability and/or prohibited cost of replacement heated windshields of certain Ford cars, it may be necessary to use a non-heated windshield for replacement. If so, Ford contends that the heated windshield electrical system needs to be disconnected. The following Carlite Bulletin describes the service procedure.
In a November 4, 1994 memo, Carlite indicates this conversion must be done by an authorized Lincoln Mercury or Ford dealer PRIOR to the non-heated windshield being installed. Failure to do so, may result in problems with the vehicle's electrical system. It may help to provide this bulletin to the dealer.
Carlite Service Bulletin Article No. 94-24-1
ISSUE: When replacement of the Electrically Heated Windshield is needed, the customer may want to avoid the high replacement cost of the original windshield. If the choice for the non-heated (conventional) windshield is made, disabling the heated windshield system controls is necessary.
ACTION: Refer to the following procedure for service details to disable the Electrically Heated Windshield system for installation of a conventional windshield.
CAUTION: CHECK GENERATOR VOLTAGE OUTPUT (13.OV TO 15.OV). IF NOT BETWEEN 13.OV TO 15.OV, IT COULD BE DUE TO THE FOLLOWING PROCEDURE NOT BEING PERFORMED WHEN CONVENTIONAL WINDSHIELD WAS INSTALLED. IF THE FOLLOWING PROCEDURE WAS PERFORMED, SEE THE CORRESPONDING VEHICLE'S SERVICE MANUAL FOR TROUBLESHOOTING.
9. Reconnect (-) negative battery terminal.
The heated windshield is now deactivated. When pressing the Electrical Heated Windshield 'ON' button, the 'ON' indicator will not illuminate. Also check for generator voltage at the battery with the vehicle at idle. Voltage should be between 13.OV to 15.OV. If not, see the corresponding vehicle's Service Manual for troubleshooting.
