My 2003 2500HD owners manual lists a part number for a cab ar filter, but there is no reference to it in the text. I previously had a 2001 and it had a cab air filter under the dash. The 2003 is not the same. Is there a cab air filter?
No! It was removed for the 2003 year. Wasn't that nice of them. From what I understand they were having to many complaints of poor heating and cooling as the result of not changing the filter, so they decided to remove it.
Yup, another standard feature dropped by GM. There was a group of people on another page that were looking into whether or not the cavity was there for the filter. I can't remember where I read it, so I don't know the outcome... Would like to have the cab filter back......
