so my passenger side window crapped out on me so i bought a new regulator one from ebay and i installed and it works just not how its suppose to first off the window goes down with no problem but going back up sucks its so slow and i cant just hold the button for it to keep going up cause eventually it gets stuck halfway and i have to help it up the other half i`ve searched around the site so im not another person asking a dumb question that been answered 100 times before but no luck .......

 

silicone spray lubricant. do the side rails. ull be ok. dont use white lithium because it dries and it will make it worst

 

Silicone spray in the rails will do ya, if you're cheap or have wd40 that works too, just don't get it on the window
