Can anyone help me locate the cabin air filter on an '05 2500 HD? I have removed the underdash panel on the passenger and do not see anything that looks like it is removable. Thanks

 

does not have 1...abolished on 03 and newer trucks

 

My 03's A/C stinks like a moldy filter unless I put it on recirculate. What would cause that if there is no filter?

 

the evap is staying wet..just like wet clothes will begin to stink...
try drying it out before you kill it...turning the a/c off,but leaving the blower on.
in extreme cases,there are sprays you can buy that kill microbial growth...you drill a small hole in your case,and stick the straw in and spray her down

 

Moisture still builds up in the vents from condensation. There is a couple of products out there:
Clean Air Duct Treatment and Clean Air Genie
