Heated Wiper Park
WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The heated wiper park grid (located within the lower painted area of the windshield) receives power from the heated wiper park relay located in the underhood auxiliary junction box (AJB). The heated wiper park relay coil is connected to a fused circuit from the underhood AJB. The heated wiper park relay is controlled by a switched ground from the dual automatic temperature control (DATC) module heated wiper park ON/OFF switch. The heated wiper park grid is automatically activated by the DATC module when ambient air temperature drops below 3° C (38° F) and will shut off automatically when ambient air temperature rises above 3° C (38° F), or if the vehicle voltage is low.
