Window will not go down enough...

[papasmurf]

Yes, I have used the search function here (as well as google and youtube) and read the other threads with potential solutions to this problem. The regulator in the car is a replacement that I put in about 3-4 years ago I am guessing. I don't remember the brand but it is not OEM. The window drops about an 1/8" inch compared to about 1/2" for the other side and of coures catches on the roof most of the time. My microswitches on the handles are operating correctly. I have tried adding zip ties to the bottom two pulleys on each end of the door but it has not made much difference (maybe just a bit better). I can push on the window and there is about 1/2" slack or so before there is resistance from the regulator tension. Is this regulator shot too or is there some other potential fix I am missing?
