IPMA Camera Windshield Defrost Heater

The camera windshield defrost heater keeps the windshield in front of the IPMA clear of frost and ice. The IPMA uses input from the front camera and the ambient air temperature to turn the camera windshield defrost heater on and off. Voltage and ground is supplied to the heater by the IPMA. The heater may be commanded on if the ambient temperature is below 5 deg.C (41 deg.F).

The IPMA camera windshield defrost heating element is integral to the windshield and can not be serviced without replacing the windshield. The IPMA camera windshield defrost heating element is a resistive-type heater grid that is adhered to the inside of the windshield directly in front of the IPMA camera. Before replacing the IPMA camera heated windshield element or the IPMA for an IPMA camera heated windshield element concern, verify the integrity of the wiring, connectors and terminals on the jumper harness.
