Noises problem
2006 Chevy Colorado 6 cyl Two Wheel Drive Automatic 785000 miles

I see in at least one other post that you said the Colorado does not have a cabin filter - is that true for 06?

Also, can oi assume the guy at the quick oil change place was messing with me when he pulled a filter out fro the firewall area (passenger side) and told mew it was the cabin filter and needed replacement?
