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..

 

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

 

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 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
