Where is the cabin air intake located for my 2007 GMC Sierra Classic?

Starting in 2003 GM discontinued cabin air filters in trucks, so there is no cabin air filter in a 2007 truck.

I can't say the precise reason but one GM service manager told me it was mostly because it was a contentious service issue in that a large percentage of owners had no idea one existed in their vehicles till the A/C system developed problems due to the filters being plugged. And when they were charged by dealer a confiscatory amount to replace them GM received countless customer complaints.

Here is a link of you would like to reto fit a cabin air filter to your Sierra.
Good luck and keep us posted. http://www.dieselplace.com/forum/showthread.php?t=48973&highlight=retrofit+cabin+filter

Not looking for the filter. I asked, where is the cabin intake? Where does the outside air enter the truck?

Sorry my bad, through the wiper cowl in front of windshield. The louvered area where your wipers are, you will have to take cover off to see the intake air ram tube to your cabin intake.

Good luck and hope this helps.
