Hi guys!
I'm in need of some assistance. My wipers don't work, but let me explain.
They stopped working gradually. Sometimes they would work and sometimes they would. When they finally died the only way I could turn the wipers on was to set it on a desired speed and then squirt some water and then they start going in the desired speed.
I took out the control unit and disassemble it and it seems to be fine form electrical point of view. I measured the resistance coming out the 3 pin connector and it changes resistance on pins 1 and 2 depending on the selected speed (third one is for the button on the handle).
It goes like this:
]
Are these the correct values for the speed selector on the control handle?
Assuming they are I tried to find the relay box to check there but the cables go behind the steering wheel and I could not reach there.
Where is it located? My conclusion is that the motors are working fine since the wipers work then squirting washer fluid. The switch works because there are different values when rotating the switch and I could turn them on by engaging the wiper fluid squirt. The only thing that remains is the relay box that I cant find. Any help?
Car is Fiat Grande Punot 1.3 Diesel 55kW 2008.
Thank you!

- Full speed - 0 ohm
- Normal speed - 93 ohms
- Intermittently - 316 ohms
- Off - 1160 ohms
