Ran right into this mess on my Intrepid.
That trim on the doors has to be removed as a "window frame" assembly. All of that rubber and trim comes off in an one piece. First, you have to remove the window glass, and all the weatherstripping around the window, then there are several studs and screws that stick thru the door, with nuts on them that have to be removed, just below the window level on the door frame. You will see all the fasteners once you pull all the door panels off and remove the glass.
I think other than the outer skin, the front doors on the Intrepid are the same as the Concorde and 300M. If so, the glass does not need to come out - all the screws along the lower horizontal strip are accessible with the glass in place. The weatherstripping has that black goey stuff holding them to the door - that can be a mess. On the rears - yeah - the glass and the rear track have to come out - a very precise order has to be followed as it all fits like a puzzle - go in the wrong order and things jam up - the key is to go slow with a lot of patience and back up when you need to to change the order in which the pieces are being moved around/extracted - if doing more then one, you'll learn the pattern - BTDT. That's why I said the fronts are a lot easier than the rears.
The whole mess is only available as an assembly, as far as the dealer is concerned, if it hasnt been discontinued.
I priced them new a few years ago, and they were typically in the $125 to $175 each range - likely higher now *if* as you say they are even available. Was moot then as I wasn't going to put several hundred dollars into those.
Other than that, find a car at the yard with good window frames, and you'll be good. Likely they will need to be repainted, they are prone to fading....but if the car has been garaged, the rubber wont be a mess. There is a slight difference in 01+ frames, but it is hardly noticeable, and seems to be the better quality and easier to locate in good condition in the yard.
Dan - are you speaking of your '98? I know that on the Concordes, the rubber they used that year was inferior and came to pieces - not so on 99's and up. I did what you said recently in restoring my '98 - hand picked good ones from 99's from salvage yards - that way the rubber edging is in good shape. I also found that you can restore the finish on those by scrubbing real good with Back to Black and Mr. Clean rubbing pads. They all cleaned up beautifully, and there was no damage or wear thru of the original black finish.
As far as the rear glass, the weatherstripping/rubber is glued in with the window. Have to cut and pull the glass basically. It was included with the glass from Dodge as of 06, but also available in the aftermarket....not sure what the situation is now.
The southern sun is a bitch on rubber.
Yeah - I attributed that to the low quality rubber they used on the '98 MY - I could be wrong about that, but is based on what I've consistently seen in salvage yards on '98 vs. '99 and up. Like I said earlier - the replacement window used to be $400 to $600, OEM and aftermarket, plus install labor! I don't know what they go for now. AFAIK
, the rubber is not available separately (other than "universal" aftermarket strips that can be glued in place - really look like crap even from a distance).
Here are photos from my recent restore on my '98. I replaced the rear window with one I cut out of a junker - see before and after in first two photos. I had a professional glass company do the R&R (remove before painting, replace after painting) of the rear window for $125. Also, I replaced all 4 door window-frame moldings with ones hand picked from 99's in the salvage yard purely because of the rubber edging problems on the 98's (see 3rd photo - all 4 moldings were that bad). The finish on all cleaned up beautifully with Mr. Clean sponges and Back to Black. I prefer the appearance of the '98-'99 window moldings, and was glad to be able to restore those well and easily with the Mr. Clean and Back to Black. I don't have any close-ups of the window moldings, but the last 2 photos show the overall result:
