my thoughts exactly - I replace the filter in my '99 Acura every 15k miles and it is very dirty and black...good to know GM thought that it was ok to pass this through to the cabin

No cabin filter... I would check the air intake above the passengers side feet... I had a plastic bag get sucked up and stuck in my 97 Tahoe and had the same results, lots of noise but hardly no air....
