Rear Window Defogger Relay:

2. Remove the rear window defogger relay (EBL) from the Junction Block.
3. Using voltmeter, test battery voltage:
a. Test rear window defogger relay terminals 13 for battery voltage. If voltage is OK, goto Step b. If voltage is not OK, repair A4 circuit.
b. Test the rear window defogger relay terminal for battery voltage with the key in the run position. If voltage is OK, go to Step c. If voltage is not OK, repair A31circuit.
c. Use a known good relay. If not OK, repair circuits as necessary.
