I believe there are 2 versions of the weatherstrip assembly. Some models have a black-colored weatherstrip (no chrome at all) which is found on the FE and LXS, while the EX has a chrome weatherstrip with the black strip. If you do a search of used car listings, you can see the different weatherstrip that was used on the Forte models. If you buy the correct weatherstrip assembly for the EX (chrome piece with black strip), it will come all assembled and all you need to do is install it. The chrome on the weatherstrip is designed to match the upper window trim, which on EX is chrome. The upper window trim for FE and LXS is all black, which is why the weatherstrip is black for those models. If you're concerned about getting the right version, be sure to enter your VIN when placing the order and usually they will confirm you ordered the correct parts for your vehicle.

oh my god you're absolutely right. I was looking at different kia models and noticed some have black molding.

I think where I was confused and also why that other gentlemen began losing patience with me is that I thought that the chrome molding and the black weatherstrip (the part that touches the window) comes SEPARATE. I think that's where my disconnect was occurring and why I didn't understand him. So whether you buy the black or the chrome molding, it already comes with that black weathertrip that's touching the window. That's the weatherstrip that is deteriorating on my car and separating from the chrome molding. And now it makes sense why there's 2 different parts on the KIAparts website. I am assuming the one labeled as BRIGHT is the chrome one?

I think I'm slowly piecing this together. I figured out which part # is the bottom molding and the top molding.

These part #s can get tricky.

It looks like the 2 part #s circled in red are the TOP molding of the door, and the ones I circled in green are the BOTTOM molding.

Just noticed yesterday my 21 LXS has the same issue on the drivers side which in daily use is exposed to sun more than the passenger side. I was coming here to ask if anyone else encounter this issue and behold someone best me to it. Looking at the utube video it appears doable just need to find the correct parts, my local dealer parts department is not very accommodating.
yes there is a variety of deterioration on the weatherstrip on all 4 doors of my EX. On the drivers side door is so bad that when it gets hot in the sun it will stain the sleeve of my shirt with this black crap.

Mine is a 2020 with 115k miles on it. I've lived near Miami the past 3 years and I guess it's taking a beating. I don't have a carport or garage unfortunately. I'm curious how do you pop these out? Do you have to insert a flat head screw driver to pop the clip? The guy in the video I posted above just used a little pry bar, it looks like the thing I use to remove the clips on the engine underside cover.
 
Went by my dealer, they had the parts in stock they are priced at $107 front door and $105 rear door, told him that those are expensive parts to only last 3 years, he suggested I talk to service, service took pictures and said they would request warranty. If the parts were more reasonably priced I would have purchased and do a self inststall but at $400+ for all doors for a strip of rubber that's hard pill to swallow. While waiting for warranty request going to look for better prices. Can kick myself in the but for not getting part numbers while I was at the parts counter.

Hang on, when they said 107 for the front door, did they mean BOTH front doors, or just a single door? Also how many miles on your Forte?

My interpretation is the same as yours, red circled part numbers are for the upper window molding, while the green circled part numbers are the window belt molding pieces that you are looking to replace. I would confirm part numbers with the dealer before placing your order, just to be on the safe side.
Absolutely. When you look on the diagram it shows 2 different parts numbers, one is for the LEFT HAND door and the other is for the RIGHT HAND door.

Part # 83220 is the REAR PASSENGER WINDOW. Part # 83210 is the REAR DRIVERS SIDE WINDOW.

So from the same window you can order both moldings for the LEFT HAND and RIGHT HAND passenger windows.

It will be the same way when you go to the front window part #s.

And I will double check with the Kia parts website that these are the correct part #s for my 2020 EX.

Here's the link in case you need it. Although you probably have a different model.

Rear Door Moulding - 2020 Kia Forte

This is a huge relief for me, I really didn't want to have to visit the dealership or body ship to do this. It will cost roughly $200 for all 4 windows. Maaaaaan this car better last 200,000 miles.

just a thought, if the ex version failed where you are. What about replacing it with the GT-line trim? Would it fit?
it will still be the same rubber weatherstrip that my car came with, except instead of a chrome molding it's just black. It's still the same piece of rubber weatherstrip. At this point I'm used to having it chrome. I mean they did last almost 100,000 miles.

But you know? I've been spending a lot of time in professional detailing forums because I'm a fanatic at keeping my car clean, and I realized that certain cleaning/detailing products are petroleum/alcohol based, and will deteriorate any rubber moldings. So when I'm spreading something like Rain X on my window, which I've been doing since I first purchased the car, if I spread too much Rain X on the rubber weatherstrip it may cause it to dry out and crack. I learned this the hard way a few years ago, I ruined a nice pair of PIAA windshield wipers because I kept cleaning them with an alcohol based cleanser. They eventually stopped working well and would streak and chatter all the time. Many manufacturers will say you can clean their wipers with alcohol. I think with silicon you can get away using alcohol, but on rubber, if alcohol is used too often it will dry it out.

Same goes for petroleum based products. You cannot use a petroleum based product on anything that's rubber because it will cause it to swell or deteriorate. It's possible I have spent the last 4 years using Rain X on my windows and may have caused it to prematurely crack. Although more than likely the excessive sun here in South Florida is the biggest factor in the rubbers drying and cracking.
 
Petroleum distillate + sun light = cooking vehicle interior plastics & rubber parts.

Petroleum distillate on leather will damage it. It will harden & cook the leather. It will leave & feel a hardened & baked surface, like burnt pancake

Yup. That's why I stopped using petroleum/hydrocarbon based tire shine, because it can eventually crack the sidewall.

The rear weather stripping part (83210M6000) that the dealer quoted me $105.00 I just ordered on line from Kia Parts Now for $53.00 including shipping
Yeah they're all just under $50 at KIAparts. So you got the black one for your LXS. When you get to installing it can you let us know what tools you used and how exactly you removed it. I'm thinking it pops straight up, not to the side. Make sure not to damage the paint if you're using a pry tool.
 
Post the repair, install pics if you diy. It'll help the forteforums community.
The part I ordered from KIA Parts was received damaged, poor packaging, it was bent somehow and had a kink in the center, still waiting for a refund, took a chance and drove up to the service department at my dealer, asked about warranty, service manager said they would have to take pictures and submit to the warranty department, will call me in a couple days, couple weeks later went back to inquire and was told they would cover the drivers side, but not the passenger side because it had not deteriorated enough, anyway drivers side was replaced Friday, took less than an hour in and out. Told me to come back when the passenger side worsens
 
I also recently inquired about warranty coverage, but got denied due to the age of the car. They cited acid rain, sun exposure and other environmental factors, beyond Kia's control. They sent pictures to Kia, but about a month later, I received another call reiterating the denial so I'm going to order the parts from the dealership in the next month or so and install them.

For reference, below is a photo of the right front door, which is in the worst condition in terms of the weatherstripping. You can see the weatherstripping is peeling at the edge and some of the material has worn off. The other doors have a similar issue with peeling at the edge.

In the past, as a stop gap measure, I had success carefully using a drop of superglue to hold down the portion that is peeling back but it changes the texture of the material for the glued area (it will be wrinkled instead of a smooth surface) and you have to be careful not to smear the glue everywhere. The glue held down the rubber for a few years.

I do not believe the photos taken of my car were submitted to KIA, from conversation what I think I understood they have an in house warranty department who made the decision
