Does anyone know if a 2004 Silverado 1500 LS with dual zone manual HVAC system uses a cabin air filter? With the bottom panel off I can see an area on the box that looks like the filter may go there but I cannot figure out how to access it.

I think 2002 was the last year cabin air filters came stock. Pretty sure you don't have one.

My truck is an '04 just as you describe yours. It has NO cabin air filter.

I don't remember where I saw it but there are instructions out there on how to do a conversion to install cabin air filters in the post 2002 nbs trucks.

Thank You Guys!

Note - reason it only goes to 2006 is because that was when this was released. There was 3 yrs of uncertainity mostly because the fiter manufacturers catalogs continued to list them past 2003.


Models: 2003-2006 Cadillac Escalade Models
2003-2006 Chevrolet Avalanche, Silverado, Suburban, Tahoe
2003-2006 GMC Sierra, Yukon Models
2003-2006 Hummer H2

Condition/Concern:
A customer may inquire about the availability of the passenger compartment air filter.

Recommendation/Instructions:
Starting in the 2003 model year, the passenger compartment air filter is no longer available as a factory option.

They were deleted because they were a major source of customer dissatisfaction due to the added cost to service them. There were 2 of them to replace and the dealer charged an arm and leg to replace them.

Personally I wish they had them, yes it's a cost to change but it keeps the interior cleaner and helps the evap core last longer by not getting as dirty without. There is a way to retrofit your case if you wanted to. It's a lot less expensive to replace a cabin air filter than to pay to have the dash dropped to change evap core.

Yes, I would like to do that mod. I will do a search and see what I can find.

Here's a link to a kit for the mod http://www.dieselplace.com/forum/76-spe ... lable.html

Sorry for the thread resurrection, but I didn't think my question was worth a new thread...

Short story:
About 2 years ago I spent all summer working landscaping while I was between jobs, mostly building terraces for people around their houses. Due to this I hauled a lot of wall blocks and topsoil with my 2011 Sierra; being at the yard so many times with a bunch of soil dust flying around and AC on made a mess and smelled in the cabin. Every now and then when the humidity/heat is right, I'll still get a fairly strong soil smell out of the AC, although it does go away after a few minutes.
At first I thought that the cabin filter was retaining the smell, and that I could replace it and be good, but now I realize that 2002+ don't have cabin air filters

So, any thoughts on what could I do to get rid of that residual soil smell?? Would the retrofit be a solution?
It doesn't bother me too much, but would like to try and get rid of it...
TIA.
