Wiper Relay: Testing and Inspection

WINDSHIELD WIPER RELAY ASSY
a. Operation Check
1. Using a voltmeter, connect the voltmeter (+) terminal to terminal 4 (LM) of the connector, and the voltmeter (-) terminal to terminal 6 (LS).
2. Connect the positive battery (+) lead to terminal 3 (+B) of the connector, and the negative battery (-) lead to terminal 6 (LS). Measure the voltage between terminals 4 (LM) and 6 (LS).

Standard: 10 to 14 V

b. Intermittent Operation Check
1. Using a voltmeter, connect the voltmeter (+) terminal to terminal 4 (LM) of the connector, and the voltmeter (-) terminal to terminal 2 (C1).
2. Connect the positive battery (+) lead to terminal 3 (+B) of the connector, and the negative battery (-) lead to terminal 2 (C1). (Wiper switch is in the INT position.)
3. Connect the positive battery (+) lead to terminal 5 (SM) of the connector for approximately 5 seconds.
4. Connect the negative battery (-) lead to terminal 5 (SM) of the connector. Measure the voltage between terminals 4 (LM) and 2 (C1) when operating the intermittent wiper relay.




Standard: Refer to the illustration.
