Here is a cool PDF showing where cabin air filters are located and how to replace them if you have one in your vehicle. You need to know the Wix part number and you can find that information here just put in your year make and model and it will bring up what your vehicle takes, find the Wix's cabin air filter and use the PDF above to locate it in you vehicle.

They did away with them on the GM trucks back in 04.

I had an 03 Silverado and it didn't have one either......even though the dude at NAPA sold me one, and I looked for it for hours, until I found out the truth!

It must have been a later model production year 03.

Just changed mine out a couple of weeks ago.

It seems to me(if memory serves me correct) Bernie B has a unique situation with his service truck pertaining to location w/ his make and model and it being a PITA.

Begging in 2003 they were not longer available in GM trucks.....

HVAC redesign left no provision.

I should probably change mine.
