True or False
Took my 15 into the dealer last week to find out what was wrong with the AC. Thought maybe low on freon. Could only get semi cool air when I selected bi-level but colder when selected dash vents. No cool air on my feet. This was in the high 70's to mid 80's outside temp. This past spring driving in mid 30's outside temps I could only get heat at my feet when in bi-level. I get a little bit of breeze blowing thru my defrost vents all the time. The dealer told me that was normal because anytime the humidity inside the car is above 30 that's the way it's supposed to work. It's not in the owners manual but the tech's manual. I also asked if he could program the "blow by" to run the fan a few minutes after shut down to see if it would clear the musty smell. His response was no way can they do that!
Is this true or am I getting the typical dealer song and dance?

Afterblow is what I think the OP is after, not blow by. Afterblow is off by default, but can easily be turned on by a knowledgeable tech. Most modern GM vehicles have the feature. Criswell turned it on for me during PDI at my request. Many others here have had it turned on by their Chevrolet dealers.

Yep, find another dealer for a second opinion.
