Heated Glass Element Relay: Testing and Inspection
Component Tests
HEATED BACK WINDOW RELAY COMPONENT TEST
Use 73 Digital Multimeter to check for the continuity between terminal 85 and all other terminals. If resistance is 5 ohms or less between terminal 2 and
any other terminal, replace the relay. If resistance is greater than 5 ohms, continue with the test. Use two jumper wires to connect relay terminals 86 and
30 directly to the positive battery terminal. Use 73 Digital Multimeter set in the volts position to check for voltage at terminal 87A. If battery voltage is
not indicated, replace the relay. If battery voltage is indicated, connect a third jumper wire to terminal 85, and ground the jumper wire to a known good
ground. Check for voltage at terminal 87. If battery voltage is not indicated, replace the relay.
