Not too hard to replace. I replaced the regulator in my mom's '98 Town&Country because the dealer said it detracted $1000 from the trade in value. Okay so we were quite pissed, so we went to a junkyard and bought a used regulator for $45. If the Intrepid is similar to the T&C (which i assume it is), it installs just like the old one, just take off the door panel, unscrew the regulator (make sure the tracks are still aligned) and replace it. Watch out for the plastic black tabs, they're a safety feature to keep from smashing body parts when closing the window.
btw, the new '02 Town&Country LXi has steering wheel controls
Ive had to replace the passenger side rear twice. The new motor in there is crap because it is slower than all the other windows, have to be sure its all the way up because Ive left it in the rain before, it was not a good thing.
