The front washer jets in my Peugeot 206 (year 2000) have stopped working recently - the rear one is still working fine.
The vehicle is using a single twin-outlet pump to control back and front washers. The pump has a two-pin connection (GND, 12V) which, I believe, is inverted by the BCM depending on which washer is needed.
I have checked the most common issues:
- The stalk itself is not the problem - pushing it down normally activates both the wipers and the washers. The wipers still go off when pressed.
- It is not caused by clogged pipes - the motor does not engage for front washers.
- The fuse is also fine.
After connecting a multimeter to the pump's cable, I have discovered that no power is delivered when the stalk is pressed down. When engaging rear washers, -12V can be observed.
How can I diagnose the problem further?
