Cabin Air filter
 

Reminder: Don't forget to change out the Cabin air Filter on Your GM truck after 15k miles or One year. They do exist on trucks/suv from 99-03NBS. They stopped adding them since no one over changed them.

Recently changed mine after a year and half of owning the truck since my a/c couldn't blow cold air very well. And what a huge difference, and no weird initial smell when the A/C cranks on.

Easy to replace them, They are located underneath the glove box. You have to remove the Plastic kick pannel on the passenger side (4 7mm screws) and u can see the access panel for the Filters. its tied down with a gold screw 5mm IIRC. and theres 2 filters in there. The Air flows from the passenger side over the the driver side fyi.

Heres a pic, i beat the filters on the ground to get the loose dirt out, and they're still really dirty.

Are these in the early 90's models too? Thakns for the heads up Dano.. i never even thought about that..

:U:

it wouldn't hurt to check, its around the glove box area, the minivan at work had them in the glove box department.


But ur good, ur lbz dont got one. but u can add one if you want. i know of a guy who makes them

They are on '99-'03 new body style only and there are 2 filters side by side in the same location.

reminder for guys with the cool trucks

mine doesn't have them

so 04- current dont have them?

you got it :U:

My 99.5 Silverado gasser had them... And they made all the difference in the world when i changed them. Very much worth changing... I either paid $12 or $24 for the two of them - can't remember... Either way, cheap!

took a look for them, because my ac doesn't seem cold enough, but i couldn't see the access panel:humm: I remove what appeared to be a censor of some kind and looked inside with a flashlight and all i could see was the fan impeller and what looks like a radiator. am i in the wrong spot?
let me know, was planning on getting the ac system checked but would love to save a few $ and do it myself

I've also heard that they stopped putting them in the cabins at some point... don't really know when they stopped (ask a local dealer what years they made them in).. From the description, it seems like the radiator thing you saw was prolly the heater core... JMO!

In my truck(s) there is like a one inch wide piece of plastic under the passanger dash that has a screw in it, you pull the screw and drop that piece... that piece holds in one of two filters... you pull the one out and then reach in and slide the second one over and pull it out the same slot... you replace in reverse... It costs like $12 for both and took less than five minutes start to finish...

they stopped in 03

ok so they still have them in the 03's or they dont... i had to replace the blower motor relay and figured since i had it apart to change them... there isnt anything there to unscrew on mine...

It's not hard to figure out... This is also speaking from my experience of my 1999.5 and 2001...

You unscrew (3 screws) the cover that protects all that stuff under the passenger side dash (I wanna say 7mm socket maybe)... There is a (about 3/4" wide) "L" shape strip of plastic that has a hex screw head showing (obviously attaching this piece)... Pull that screw... The other end of this cover slides into a slot... Once that piece is removed, pull your filter out, reach back in and slide your other filter and pull it out (would not hurt to vacuum what you can inside the housing)... Replace new filters in reverse...

It's pretty much common sence and easy to do... If you have filters, you will understand all this, if you don't have filters, then you won't have a clue what i'm talking about... It takes as long to type this as it does to change them out...

Hope you figure it out... :tu: :pca1:
