Windshield Wipers not working (S13 240sx)

[Jay24/7]

My car:

1992 Nissan 240sx
Red Top Sr20det - Stock
Fmic
Lowered

The Problem:

So basically when I turn my windshield wipers on, on the variable setting they do not work. When I use the sprayers, the sprayers work but the wipers do not move. The wipers only work on medium and fast. If I turn the wipers off mid wipe they stop and do not return to the "rest" position.

What I have done so far:

A year or so ago, I replaced the wiper motor and the wiper amp (green box near master cylinder). As well as rewiring the wiper motor.

Fairly stumped and do not know where to look. going to look at the wiring under the driver side fender tmrw. Any ideas would be great.

Thanks,
J

There's a time control unit behind the driverside kickpanel, it could be faulty.

I have the same problem. After just throwing parts at it and still having the same problem I finally got off my lazy a** and diag'd it. It turned out that the Wire going from the sjc(?) to the wiper amp has an open in it. the easy way to check this is to check to see if the TCU is putting out voltage. it should go from like 12v to like 3v and back again. if you dont have that it could be the TCU. If that checks you could check to see if the wiper amp is getting power. Thats y mine is not working. hope it helps.
