Our Rams did not come with Cabin Air Filters

The factory began installing them at the factory in January 2017
My 2016 Ram was built in December 2015, so the CAF had to installed, which includes cutting into the Climate Control Box, directly behind the glove compartments.
Even the new Rams only have the rectangular hole cut out & the CAF Door installed, i don't believe that they install the filter, but i may be incorrect.

I just had Carl Burger cut the hole in the box, Install the door to cover it & after that i went to buy a WIX Charcoal Cabin Air Filter & Carl Burger installed it also.
I am 78 & i can't twist my body around under the dash any more

There are several YouTube Videos showing how to do the CAF, Cabin Air Filter
There are a few about how to pull the whole Climate Control Box out of the cab & who to buy the broken CC Doors from.
If you are going to pull the CC Box out of the Ram.
FIX EVERY DOOR, broken or not & use a much better Brand than Mopar
Also, if the Ram is over 10 years old, check out the Condensor & Heater boxes that are inside of the CC Box

GTyankee,

Thank you so much.

I installed a Napa CAF in my 2016 Ram 2500 Tradesman Power Wagon today. My Power Wagon was built in late 2016 and it didn't come with a CAF. I didn't know until yesterday after 85,000 miles of driving it that it was already setup for a CAF, until I just read about it. Sure enough upon checking it did have the CAF door installed, but without a filter. I've replaced/maintained CAF's in several of my family's vehicles for over a decade. Probably have replaced over 20 of them. Always wished that I had one in my truck too, but it is a Tradesman and so I just figured it wasn't an option on the cheaper trim.

I've been eating a mouthful of dust while driving both behind and while passing by other trucks on our dirt roads. Had to do something about that. My area of Northwestern Colorado is under exceptional drought conditions which is the highest tier level, beyond extreme drought. Dust and dirt covers everything out on the road. The CAF is a nice feature to finally install in the HVAC.

Glad you got it done by yourself to save a lot of money on shop labor and on the parts. My buddy just recently spent $1200.00 on his 2014 Silverado to have a very badly designed high failure rate part replaced.
Some years back a friend of mine had a third gen that had a blown evaporator core. That was a pain in the ***, you had to take the whole dash apart, pull the bench seat and drop the steering column. We replaced both the evaporator core and heater core at the same time. Took roughly little over four hours to do the whole job.
I just don't understand why they don't engineer these hvac boxes to make it easier to replace the heater core or evaporator core

Ford use to, may still do, have a commercial "fords better idea". I remember years ago my mother in law coming to my house with her '79 lincoln town car in the dead of winter asking me if I would change her heater core because she had no heat. I ask her if she had any idea what that consist of which she didn't. I had no garage at the time and had to do it in my driveway in the winter time. Well I couldn't let her go without heat so I reluctantly went out to start taking the dash out, I opened the hood to disconnect the battery and I noticed right above the heater hoses on the firewall was a rectangular plate with 4 screws so I took the plate off and to my surprise there was the heater core. I took the hoses off, lifted the old heater core out, put the new one in all within about 10 minutes. Talk about happy. When I went back in she of course couldn't understand what the big deal was I was making it out to be. I said, "after all these years I finally found out what fords better idea was!" Haven't seen it since but I seen it once. Can't believe still after all these years manufacturers haven't been smart enough to put a plate on the firewall to access the heater core and evap. If ford can do it anyone can do it, even they don't do it anymore!

I had to change my heater core early this year. It actually took 3 days, a couple or 3 hours each day, working solo. So I'm slow too. But I had another car to drive so was in no rush. It could be done in a weekend, or even one long day especially if you have a buddy to help. Honestly it wasn't that bad of a job, the only part I needed a hand with was getting the steering column back in place, it was just a bit awkward being upside down under the dash lol.
Here's a link to part 1 of a 4 part really helpful video.

It was worth it, figure I saved a grand and now I have HEAT!

It's pretty easy. I had mine ready to pull out in under an hour on a 13 3500 with a Cummins engine. If I'm not mistaken access is better with the 5.7 to the firewall bolts. On mine it was easier to pull the lines into the cab to access the hose clamps. If your slow it's a weekend job and still easy. It just looks daunting. If you have a buddy or capable spouse it'll make a few things easier but for the most part this is a job 1 person can do.

I have an 84 D350 with bilevel AC. From the engine side the heater connections are at the far left and the AC connections are at the RH bottom of the unit. I cannot find a diagram of the unit to troubleshoot the defroster & heat which are both lacking.
