Power Window Relay

POWER WINDOW RELAY INSPECTION




Perform this test when directed in the diagnostic pinpoint tests.
1. Measure resistance between terminal 85 and terminals 86, 87, 87a and 30. If the resistance is 5 ohms or less between terminal 85 and any other terminal, replace the relay. If resistance is greater than 5 ohms, go to step 2.
2. Use two jumper wires to connect terminals 86 and 30 directly to the positive battery terminal. Measure voltage at terminal 87a. If there is no battery voltage, replace the relay. If there is battery voltage, go to step 3.
3. Connect a third jumper wire to terminal 85 and a known good ground. Measure voltage at terminal 87. If there is no battery voltage, replace the relay.
