Does a 2004 Envoy have a replacable A/C filter and if so where is it?

Wait! What! My 2005 TB has a cabin filter?

G'wan - you're greening me!

EDIT ---> Amazon has no such listing for my vehicle.... so do I do or do I don't have one?

At 99.99% you will not have a cabin filter (2005). Unless of course the previous owner did not put it :)
I met cars only until the 2003 release equipped with a cabin filter, maybe in 2004 it is, but rarely ...

Thanks, Vega - I 'retired' in 2004 so I never saw these vehicles in any of my shops - they were all on manufacturer's warranties yet so why should anyone pay to have factory screw-ups repaired?

OK - I guess I'm STILL NOT REALLY ACTUALLY RETIRED - not in a classical sense anyway!

TBs and rtheir ilk are a learning curve for me right now - but it's more like a straight up, 90 degree curve!

Thanks for the clarification....

Unfortunately, I do not know why GM refused to install a cabin filter in the following years of production of our cars. But if there is a desire it is not difficult to install it yourself, though the original cover can no longer be bought (it has long been discontinued) but it is easy to make it from improvised materials.

Is there a location for it? Is the insides of the plenum ready to accept a filter? I can make a door for it - but I'm kinda amazed if it's a do-able thing.

Yes, there is a place for installation, all you need is to cut a window in plastic.
It should look something like this:
Do not forget to install the filter correctly, the direction of air flow is shown on the body by an arrow (marked on the photo) and also on the filter itself.

I checked mine and I would have to cut out the panel. To much BS for a 16 year old car I won't have to much longer. 2004 with only 67,000 miles.

It was relatively easy to do with an oscillating saw. I initially taped up the opening with aluminum tape, but was able to find the actual part on eBay.

The filter did make a difference on my 2004 XUV as my wife no longer complains about the dust and smell.

How about residual cigarette smoke? The previous owner (my daughter-in-law) smoked in the car so she doesn't smoke in the house.

I've got the smell down to a small percentage - but those last few percentage points are hard to get rid of even with hangy-down air fresheners that smells like Hoppes #9.

I doubt the filters would help that much as the tar is stuck to every pore in the truck. You would need to scrub down all of the interior surfaces, then use a duct cleaner like the A/C Pro Vent & Duct Cleaner Odor Neutralizer from multiple online sites.

Or just open the window . ;)
4-at-85 didn't make much difference either. Sunshine and oxygen should work --- I'm patient and I can't really smell it anyway - just "the woman" does and she has her own vehicles to drive.

The TB is MINE!

Ya know --- you're right! They say that your sense of smell is the first thing to go if you've got C-19!

Hmmmmmmmmmmmmmm..... I wonder..................
