Had the passenger window regulator fail on my 2007 Ducato motorhome. Seems the electronics in the motor had given up and the window would not wind down.
Not the easiest job to get too as all the panels had to come off before I could access the mechanism.
TIP: if the window is in the UP position, try to drive the motor to get the window half way down which allows easier access to the clip onto the window glass.
Fitted the new (used) unit and worked perfectly
Happy with price and speed of delivery from the vendor, so would recommend.
