My passenger side window goes down really easy but was hard to get back up.
Now it doesn't go up at all. Help!

 

On mine the cable was worn and snarled. I was lucky to find a power window lift assembly on ebay and replaced the whole assembly; of course this requires taking the inside panel off the door, and a lot of interior door disassembly but I found some help on this or another forum and it was not all that hard to figure out (on some cars watch to see if you have the screw in the bottom of the door pull; you have to remove it to remove the inside door panel). I saved several hundred dollars on the part and I don't know how much on the labor. Just take your time and search the forum if you run into a snag, but I don't think you will. Adjusting the window (three mounting bolts with large flange/washers) is a little tricky, make note of how the window sits in the door frame before you loosen the window.
