S13 - No power to rear wiper - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hi there,
I have an S13 hatchback, rear-wiper equipped, but the rear motor doesn't seem to be working.

Had the car a couple of months and the wipers haven't worked since I bought the car. I was able to fix the front wipers by replacing the fuse, but the fuse didn't fix the rear.

So this is what I've done:
-Replaced wiper motor
-Checked for power at the plug (the plug that goes into the wiper motor), no power
-Checked for power at the plug (next to the LHD passenger B pillar), no power
-Checked for power at the wiper amp, (next to the rear latch), no power
-Checked the switch next to the ignition, no power

I used a test light and verified that I had a good ground each time, so it doesn't seem to be sending power to that amp at all, as the break appears to be before the power switch.

I'm not the best with electrical stuff and I'm having a hard time determining where the lines running toward the Rear Wiper Motor Amp join with the main chassis harness, the schematic kinda 'ends' at plug M122 (the amp) and I can't tell where it re-joins. Also, I don't see a fuse for only the rear motor.

Can anyone help here, what am I missing? Thanks.
