Driver Side Window not moving smoothly.
DACIA SANDERO II

Hi

I have a Dacia Sandero 2017.

About 6 weeks ago my drivers side window would only go down and not up. So i had to get the AA out and the guy managed to get the window back up, but suggested it might be the switch.

I got a part that came up as similar and seemed to be compatible. However that part would not move the passenger side window at all, and the drivers side window would only go down an inch or 2 with each click of the switch so it meant you had to click it around 6 times to open or close the window. Also if the car lights were on nothing would happen at all. So i have now managed to get a hold of the exact same part as the original and everything works fine now apart from the drivers side window still has the issue of not moving in 1 movement, but rather a couple of inches with each click and sounds like it’s not moving smoothly.

So i am not sure if it’s some sort of electrical fault or something the AA guy may have done when he was trying to get the window back up and it needed some forceful pushes. 

Any answers appreciated.
