R32 Wiper Wiring

[meadan]

Hey

Im just cleaning up my car a bit and fixing all the little things which dont work.

Its an 89 r32 4 door which has had an rb25de put in by a previous owner.

Im trying to figure out why my windscreen wipers wont work properly. I have searched, but cant seem to figure it out myself.

There is a wire spliced into the wiring connected to the wiper motor, im pretty sure its coming from the ecu.

The wipers only work when i select high speed, the first 2 clicks of the switch do nothing.

There are no extra wires running to the switch from what i can tell.

If anyone has any idea where to start looking it would be awesome..

changing the motor should not affect the wipers..

i have a wiring diagram for the '32 GTS-t somewhere ill dig it up and post up if i can.

i would say someone has cut the wrong wires and not put them back in right.. or your switch may just be dodgy?

could possibly be the switch. get a multimeter and check to see if the first 2 speeds of the wipers are getting a voltage.

when they installed the rb25, it looks like the wiring conversion was a little bit sub par.

Im pretty sure its still running some of the rb20det loom. The plug for the wiper motor does have a few wires taped over so maybe it was connected the wrong one.

There is no power getting to the motor in the first 2 speeds, but there is at the 3rd.

Also, the wipers dont reset when i turn the switch off, so im thinking power is only going to the high speed wire?

by reset do you mean return to off position?

because mine dont either if i turn the key off and the wipers are halfway across the windscreen they stay there..

if i was you i would get a multimeter and untape all the wires going to the motor.. could be just that they were too lazy to connect them properly?? then you can check whick ones get 12V when you put the switch at various positions.

Did this ever get solved? Im looking for the solution to it.

I had an sr in my 32, wiring worked fine, put 25 in and had this problem.. Wtf

If your wipers aren't returning to the park position then it would be your wiper amplifier. Its a square box near the wiper motor. Either black or brown. That tells the wipers when to stop and start. If you swap one with a mate I'm sure it will fix your problem.
