I noticed a rattle in my drivers side window at the back. Thinking the glass had come unglued again, I took the door apart. The plastic wheel that rolls in the channel had broken and was laying in the bottom of the door. The rattle was the metal shaft against the metal channel. Dodge wants to sell me the whole regulator, which I don't need. (to be fair, Nissan trys to do the same thing) Any idea where I can get a couple of new plastic wheels? I tried the junk yard, but the ones I found were in worse shape than mine. thanks.
