My 2003 Yukon does not have an in-cabin air filter.



yes it does..........however it's inside the dash and you have to pull the dash apart to get to it. ask my how I know? :D I replaced the two filter elements in my '99 GMC Sierra (NBS) and at the same time bought the the one big filter element for my 2003 Yukon. when I got home I noticed it wasn't the same configuration so I went to the dealer to look at the drawing and ask them. they said you have to pull the dash apart to replace the filter which is absolute bullshit IMO.

our Yukon has gotten some kind of mildew from the moisture on the filter (you can put your hand through the compartment next to the blower motor to actually touch the element) and it makes the AC at times smell a little. The dealer told me what they do is spray a mildew smell remover in with the blower motor on and that's usually how they fix it. otherwise it's expensive as hell for all the labor involved to pull the dash apart and do it.



I had an a/c smell around 2000, dealer sprayed inside of the air box and advised me to turn off the a/c, a few minutes before you turn off the truck. Also there is a delay device, that can be wired to turn on the fan speed, after truck is off, that blows air for a few minutes. You can also spray lysol into the air intake, at the bottom of the windshield, under the black plastic vent with fan speed max, and fresh. Not recirc.

It might have a filter,But its not considered an in-cab or "Cabin Air Filter" (I.E.-Its a "non-serviceable" filter which doesn't require regular changing)
A lot of vehicles have A/C evaporator filters that are non-serviceable.

I got the same info from the dealer on how to fix it. I tried all of that. it really only helped for a little while.

that's just it. it SHOULD be serviceable because mine is contaminated BIG TIME and I think it's ridiculous that I can change the one in my '99 but not the '03.

O'Reilleys sold me the filter for the '03. I just took it back when I learned that I had to take the dash apart to change it.....

Oh I agree with you there...Like you said,once they get contaminated you can get a heck of an odor!!
We have the spray "deodorizer" that GM has out,and we use it on quite a few vehicles,It seems to work pretty good and get rid of the odor.

You would not be putting the filter in place of the evaporator core in your air-conditioner. they are not the same. On your 99, you have an in-cabin air filter that filters the incoming air and also an evaporator core for the air-conditioner. Some where around 03 they stoped putting the in-cabin filter in the trucks. They still have the evaporstor core and yes they get stopped up and stink. They do this a lot of times in all vechicles.

Now I have seen threads where people added the in-cabin filters to trucks that did not come with them.
A section is cut out where thay originally would go and a cover put over them. the next time I run acress one of these threads I will post it.

This thread does not show reto fit but has good pictures.

Don, I apologize but I"m not sure we are talking about the same thing. the filter that I received from O'Reileys and saw on the drawing at the dealer was indeed a filter. maybe the "evaoprator core" you are talking about is the same? anyway the tech agreed that it was indeed a filter than can be changed but they usually do not do it because of the expense to the customer in labor taking the dash apart to replace it. the filter looked a lot like the "cabin filter" elements I replaced in my '99 but it was bigger and of course one element instead of 2.

I have a 1999 GMC Suburban SLT. I have attached a picture of the front heat/air conditioner. I get good heating and cooling on the rear air, but very little of either on the front. Does this vehicle have a cabin air filter? If so where is it and how do I get to it? If not, any thoughts as to what could be causing the problem?

TIA

Does anybody know of a guide on how to replace these cabin air filters? I remember seeing a good one on here a while back but for some reason I can't find it.


Yes, GM-Trucks.com does have one, In cabin air filter replacement

There are lots of tech stuff in the Tech Wiki

Well, I guess that explains why I have such poor air flow from the vents on my 99. I'll have to check it.
