I figured this one out myself, with no help from Dodge, and after 3 regulators going out on me (aftermarket and OEM).

GREASE IT UP!!

What happens is, NOT only does the window stick when it's going up, putting a lot of strain on the motor, THE WINDOW GETS STUCK IN THE UP POSITION (or dragswhilegoing DOWN) just enough for the cable to GO SLACK and the nylon guides COME OUT of the motor area. SOOOO the next time you roll the window up or down, the cable is NOT going through the nylon guides, and this wears them out very quickly (kinking, grinding, crunching noise). I greased up everything so now my window works perfectly.
