Vehicle Application: 1996 Nissan Sentra GXE 1.6L
Customer Concern: The wipers don’t work on intermittent and also don’t park. On intermittent can hear a relay clicking on and off.
Tests/Procedures: 1. At the intermittent wiper amplifier, test the park switch circuit Orange wire for ground when the wipers are not parked and 12v when the wipers are parked. If not correct, the park switch portion of the wiper motor may be bad.
2. At the intermittent wiper amplifier, ground the Brown wire and see that the wiper motor runs on low. If not, the wire may be broken.
3. Test for ground on the Black wire at the intermittent wiper amplifier.
Potential Causes: Windshield Wiper Amplifier
Wiper Motor
Broken Wire
I hope this helps.
