Headlight Washer & Rear Wiper Help!!!

[rancholapalma]

Hello,
Thanks everybody in advance for your help
So my healight washers were not working, I removed the fluid tank, checked the headlight washer motor, tested with a 12 v battery....and it worked perfectly everytime, I check for voltage at the cables when i pull the arm for the front wipers washers, and 0 volts ... then suddenly, they started working..and then, stopped again..does anyone has an idea of what could it be? I read on some forum that after the 3rd pull they start working..but i pulled it like 35 times and nothing...

Also, my rear wiper was working perfectly when i wanted to wash the windows, or during the rain, then it stopped, they won't move at all, then one day, started working again, but now they dont work, it seems like they would work 1 out of 20 tries or something...
I tested the motor with 12v and it worked perfectly.... Is there a relay or some kind of circuit board where a false contact could be ocurring??


This is on a Disco 1997 SE7

Thanks for you help!!!

Head light washers only work with the lights on and after the 2nd pull IIRC.

Rear wiper could be loose or motor has a short or bad ground
