NOTE - This mod applies to 4th Generation Rams Only!
Today I had a half hour of 100% free time. Not long enough to clean the truck, so decided to do a mod instead.
Cabin Air Filter
Here are the Dodge Avenger parts that were used.
I started by emptying the lower glove box, then squeeze the sides in to release the tabs that stop it from falling out.
Just lift up slightly and out it comes.
Looking in though the hole you will find the airbox with an outline that matches the cabin filter cover for an Avenger. When cutting out, stay inside the raised rib.
This next part is optional, but I find that removing the fan to be able to reach inside is very helpful in removing the piece you cut out. Here is what the fan assembly looks like when in position. I had already removed the back screw before snapping the pic.
Here I have marks the 3 screw locations. They remove real easy with a 5/16" nut driver. Don't forget to unplug the fan motor wiring.
About 20 seconds later, the fan is out. Hmmm....I wonder what the flat rate is to replace this item......
Here is looking up into the airbox where the fan normally sits.
The air box modification tool of choice.
This is the plastic after removal. I find it easier to cut straight across the bottom and remove/optionally remove the the small lower tab. It is completely unnessessary to remove this small lower tab, but the embossing is there, so I just couldn't leave it. No one will every see it, but 'I' will know it's there... :shakehead:
Here is the opening after all the knife work is done.
Time for the filter (p/n 05058693AA) . I'm sure they could have found a bigger box.....but....maybe not.....
Taking careful note of the air flow direction arrows, install the filter. It just slides in, and sticks out a bit (~3/4"). It's a little tricky to slide in, as the hole is partly blocked by the dash. I only took about 10 seconds of patience to slip it in with any damage.
Next, the cover (p/n 68052292AA).
Slip the cover in place, and press the 2 end tabs toward each other. They will 'click' once in place.
Put the fan back in (about 30 seconds) and this is what it should look like.
Here is comprhensive list of tools.
This mod took a total of 25 minutes. Had I not stopped to take pix, it would have been between 10 & 15 minutes.
Couple of items of note -
1) Make sure you have 'sharp' knife with a good point. I DO NOT remommend using a knife with break-off blades (even the HD version). You will be putting a fair amount of pressure on the knife, and a break-off blade would likely lead to injury.
2) Went cutting out the plastic, cut the bottom first, then the top. If you cut the top first, there is nothing substantial to hold the bottom, so there is some (not a lot, but some) risk of breaking the housing.
3) With the fan removed, you can easily reach inside to puch the plastic piece out. Wit the fan in place, you may end up droping the piece into the fan, and will have to remove it anyway, so for the 60 seconds it takes to R&R, it's well worth it.
Little of both. In the fall, my Hay Fever drives me nuts, so have always installed some sort of cabin air filter in my trucks. Also, I like to keep my truck clean inside and out, and a cabin air filter sure helps reduce the interior dust. In the case of the 4th gen Rams, this is such a great way to filter the air, as it also filters the re-circulated air when the AC is on max. The only 'difficulty' in changing the filter, is you have to remove the lower glove box, but that only takes 10 seconds....so not too big of a deal.
I checked around here for the aftermarket filters, and the best I could do was order it with an undetermined ETA and undetermined shipping cost, so I opted to get the one 'off the shelf'. I am hoping to find one that has a charcoal layer to also clean the smell out of the air.
You are the master of write-ups Brad. :smileup: That's an excellent upgrade and one worth doing. I'm thinking it may be my next mod. Thank you for showing us all a great step by step process ...... My guess to have your friendly neighbourhood dealer R&R the blower motor is $250.00 plus parts
Depend where you drive. You won't changed it as often if you drive in the city all the time, but if your truck is a farm truck... You might want to check it every oil change just to be sure.
That's what i will be doing. Check it every oil change.It take 30 seconds to look at it.
I bought a 2018 2500 tradesman from dealer with 14 miles on it. I did this on 9-30-2019.... the dealership sold me an Ally premier protection warranty, coverage level Major guard.... I am now seeing spot rust and passenger door, tail gate, both rear quarter panels.... I am wondering if this...
Every time it rains, water gets trapped inside the hood panel. When I raise the hood, water will pour out of the small holes on the underside of the hood. I am thinking that it is a matter of time for corrosion to take hold. Anyone else have this issue? Cause of leak? Cure?
So on this 8 degree day in Boston I am having a bit trouble with, of all things, my heated seats.
When I press the driver side heated seat button, It will light up for about 5 seconds and then turn off. The seat does not warm up. The passenger side heated seat works properly..
Any ideas...
I'm in process of changing the drivers seat bottom foam. I've run into a step, which I'm not certain how to proceed. My seat is fully manual. I'm uncertain how to remove the seatback recline lever (see photo attached) to allow me to remove plastic trim at base of seat. Can anyone tell me how...
