- Ignition OFF, connect the KR7 Rear Window Wiper Relay.
- Test for 60-200 Ω between terminals 85 and 86.
- If the resistance is not within the specified range, replace the relay.
- Test for infinite resistance between the following terminals:
- 30 and 86
- 30 and 87
- 30 and 85
- 85 and 87
- If not the specified value, replace the relay.
- Test for less than 5 Ω between terminals 30 and 87A.
- If greater than the specified range, replace the relay.
- Install a 10 A fused jumper wire between relay terminal 85 and 12 V. Install a jumper wire between relay terminal 86 and ground. Test for less than 5 Ω between terminals 30 and 87.
- If greater than the specified range, replace the KR7 Rear Window Wiper Relay.
