So, I’ve been wanting to do the cabin filter in my 06 Silverado for a while. I YouTube some vids and take the cover off the bottom of the dash to see if I have the one with the clip off door or the one that has to be cut off. I have the one that has to be cut off and retro fitted with a new or different cover. I cut it out today and NO filters! WTH? I just helped a buddy do his 01 Tahoe yesterday. It had the clip off door and nasty filters in it. My truck is 5 years newer! No door, no filters. Again, WTH?
