Renault Megane 2 1.5dCi 2004 - Front wipers do not work - PPH1 and PPH2 together makes short circuit on wiper plug.

[Komuszon]

Hello there.

I recently had to replace with a new (used) motor for the wiper mechanism (the old one had a short circuit on the rotor).

Unfortunately, after I connected it and wanted to start the car, all electronics turned off. It was impossible to start the car, nor did it respond to the pilot.

After I disconnected the wiper plug from the motor, everything returned to normal.

I unplugged all the UPC plugs, left only the wipers, and it turned out that there is no short circuit in it. I connected and disconnected them all in turn and it turns out that PPH1 causes a short circuit on the wiper plug when PPH2 is connected.

PPH1 itself has no short circuit.

Has anyone had a similar problem or can help me?
