Frustrating problem with power windows

[MJMert]

Hi guys.

I have Corolla Verso 04, 1.8vvt-i (2004-2009 model) and I'm having frustrating problem with power windows. It all started last winter when I used the drivers window. The window motor started to move really slow and if I want to open or close the window I need to help it with my hands. It gives a small buzz noise and the lock systems clicks always when it stops (safety stopper). It seems that the motor is not getting enough power. I tried to plug the motor straight without frame, but it does the same... Well, I ordered used window regulator + motor system for it, but it didn't help. I tried the old window motor on the other side and it worked flawlessly and smoothly.

Both rear windows work perfectly.

Few weeks ago the passenger side window died. Nothing happens. Then I ordered new master switch for the window and I was hoping for the best. BUT it didn't help at all. Now I have ran out of ways to fix it. All the fuses are ok.

Should go to examine my car somewhere? Diagnostics?

Sorry my poor English. And I hope this post is in the right place, I'm new here...

Have you tried lubricating the window channels with a silicon lubricant.

Yes, not helping. It's electricity issue. Motor isn't running properly on the drivers side but same motor runs great on the other side.
