Freightliner cascadia hidden cab air filter. 

Man thanks now I got a nice blowing ac mine was. A2014 Cascadia it was horrible... Blows like a tornado now..

wow that is awesome, they designed it this way so when the blower over works itself you have to replace the whole thing, that filter is not an easy access so most likely no one will change it

So how did you get it replaced?

Remove sidewall panel next to door hinges

I called freightliner. The guy told me there’s 4 screws that drop the ac systems to access the filter. Or. Take out the blower motor and you can see the filter thru the blower motor area. Gd luck. It should be replaced once a year

Take glove box out my bass. Take the firewall off. Lol

There 2 in this cascadia one under the dash an another one is in the back bunk area

no dude from outside

How the hell do ya get to that ??

I just remove the blower motor to clean it.

Any luck?

its a 5 minute job bro you a fool lol

U take the glove box out 4 screws that’s it
