About 5-6 months ago the front passenger-side window acted funny. It would go down but not up using the switch on the master control (driver switch), if it did go up it seemed like the window motor was weak on juice or something. So I went to the junk yard and got a replacement. The window then worked fine. Then, I got a complete master witch unit off ebay. I took out my master unit and put in the new unit. Everything worked fine until a few days ago when the passenger-side window started to show signs of not working. Same thing, from the driver-side switch, pass. window goes down but had problems going up. At first the window would go up, but slowly and sometime sit would pause and I would have to presss the switch up and down. Now the master switch for the pass. window will not make the window go up--just down. The passenger switch works fine. It's just the master pass. window switch.
