Checking Fusebox

Remove windshield wiper relay 2/182 from the fusebox base.

Check the relay coil driver circuit for a short-circuit to supply voltage. Take a voltmeter reading between terminal #2 and ground in the relay base.

The voltage between terminal #2 and ground must be approximately 0 V.

Remedy as necessary.
