This is very weird and I have no idea why it just won't work anymore. I was doing a fully restored hatch and reinstalled everything back on the car. Everything else works expect the rear wiper, the rear wiper worked before I tore the car down.

I already replace the wiper switch at the column, replaced the wiper motor itself and it's fully plugged in.

Hatch wiring? Maybe, I not sure, my spoiler brake light works.

Is there a relay for the rear wiper? I doubt it but I'll never know. Keep in mind front wiper works just fine and everything else on the car works great too.

 

wiring most likely check continuity from switch to the motor then check grounds also

 

The connector in the trunk where it is for the hatch wiring hardness?

 

no, the connector it's in the rear left side of the glass .
If you want I guess I can send you the whirring diagram from the service manual.

 

yes please if you can do that. that will help put alot.

 

HI, I recently did this mod, you might find it helpful:

Check pinouts on a diagram and compare with yours.

I would check for cut wires where harness crosses from the hatch to the body, inside that rubber hose thing. But you should start with continuity and voltage tests anyway.

Let me know if you have specific questions, as I re-did the harness 3 times before I got it right.

And maybe this...

 

Alright thanks! that is something to do on my list tomorrow. test the motor 1st and see. my car is an si, so it already have a rear wiper and it was working before i tore down the car.
