Sure, but I would go to the dealer first and get the Mopar replacement filter in hand. I know the maintenance manual gives a recommended time to change these filters, but logically if things smell, your filter may need to be replaced sooner. It is on the regular maintenance schedule, also., but don't recall exactly.
One you have the filter in hand, just go under the hood on the right side up by the firewall. You will see a ventillated door in the horizontal air grille at the firewall just between the right wiper pivot and the right fender. Open that door carefully, pull out the filter and replace it.
When picking up the replacement filter, ask the parts guy if the filter can be installed "as is" or if it needs to be sprayed with something.
Perhaps one of our Service Manual owner members can enlighten us on this point.
I have had mine out (nosey), but have not seen a need to replace it yet. Whatever you do, do NOT remove the filter and then drive the car for any period of time. Doing so will be just like running a home AC unit without a filter -- you will contaminate the ducts without them being filtered.
Now that may seem like trivia to some, but if you or yours suffer from allergies, you will know exactly what I mean.
