Cabin air filter DIY

[Boog]

I don't know what the suggested change interval is on these filters but I can tell you I go down a gravel driveway at work. The yard is all gravel so dust flys a lot and all that accumulates on the cowl gets pulled into the truck on startup. I changed my filters a few months ago and just now checked them and you wouldn't believe the amount of powdered dirt and sand that had accumulated. I bumped them to release the dirt and reinstalled. I'm sure they will need it again by the end of summer. Imagine all the dust and crap we have been breathing in our vehicles before these filters were installed.
You sure can tell when they start to plug up as the air flow falls off.
It's a shame someone hasn't come up with an addon type of filtration for people who would like to have this on their vehicles that didn't come with it.

Geat post, I had no idea that there were two filters, only the first one. My manual did not say anything about two filters.
I have to go back in and get that second out. I have inherited my 2000 stepside from my father-inlaw after he passed away, he always hauled his Rotwieler around inside the truck with him.
To say the least, it always smelled of wet dog!
Thanks again for the post!

It's possible to add the filters to the 03-07 trucks. http://www.gmfullsize.com/forum/show...=145137&page=2

Does anybody know what year GM started putting cabin filters in their trucks?
I have an old style 1999 1500 4x4 and a 2001 Astro van.

I believe they were installed on some 99-02 trucks but discontinued after that. Replacement filters are still available.
Look yours up here.

do all trucks of this era have one? ive got an 01 3/4 hd 4x4 with 6L

[Boog]

No it was an option i think. 99-02 are the years. I'm giving thought to removing them from my 2000.

I added them to my 2006. Got a piece of thin aluminum at lowes that was just over the width of the spot where the filters would be (about inch and a half I think) cut to lencht, added 90 degree bend where it would hook to forward slot, drilled a hole to match cast spot on case. Carfully cut out slot big enough for filters to fit. Little foam tape on aluminium for sealing, and voila, I have cabin filters.

I guess I need to see what my 164K mile 2004 Tahoe looks like if it has one. I've owned it for 1 1/2 years. There is a listing for one.

Any chance that an '04 would still have the place for the filter but just not have a filter installed? A part was listed for my '04 (I forget what manufacturer) and I bought it but could never figure out where it went so I gave up. I drive in a lot of dust and the truck smells like dirt when the A/C first comes on.

I checked my 04 Tahoe LT and it didn't have one.

I have a 2001 chevy 2500hd with an 8.1l , and when I change mine there is debris left inside of the box. So I vacuum it out with one of those dryer lint edge attachments, it seems to clean it out well!! And keeps the mess down too!!

Probably because cars have lasted for so long without them plus filters don't do anything when you drive with the windows down (i do every chance I get).....The automakers realized it was kind of a pointless item & cheaper to build without them. Mainly because it was cheaper. The auto makers like saving a penny here & there. Per truck multiplied by a few hundred thousand vehicles, that really adds up!

I actually pulled mine out last week....didn't realize until then that the 2000 Silvys had them....Needless to say, they were pretty dirty....

[TDs6t9]

You guys are tops for sure. Just did mine yesterday. Didn't realize there were 2 of them. Feels like a hurricane in the cab now. Thanks for the post.

[nxtlevl]

Good deal...I know it made a huge difference in mine as well....Also the air smells a little better as well...hahahahaha.....

I just bought my 02 1500hd 4dr shrt bd..truck and wondered why it didn't seem to blow very hard...I'll post a pic when I get them out

[slick copper]

Thought I'd share. Just bought an '02 Silverado 8.1L about a month now. Just broke a hundred thousand miles. Looks like these things never had been changed out. Took my shopvac to it after I pulled the nasty filters out. Made a big difference to me on the quality and amount of air coming out of the vents.




Just wanted to say a quick thanks to this site and this thread for posting helpful stuff like this to those of us that just don't think or know about some things like our truck having cabin filters.

[Boog]

Your right. It does make a big difference in air flow. And you are welcome. This is why we post these things. To help fellow truckers.

Well my Cabin Air Filter, doesn't pull out from the bottom of the heater box. I see some sort of filter behind the glove box, when I drop the Glove box
