I was so disgusted by the weak air flow that I was about to trade the car in. But then I was told about the in cabin air filter that is located behind the glovebox. I took the glove box out and pulled the filter out and it was completely caked up. I used an air compressor, and even that took some effort, but once it was cleaned out, it was like magic! The air flow quadrupled, and it didn't cost me a cent. Definitely worth a check! I have never had to change or clean one of these in any vehicle before, so it was a surprise. That's another reason the glove box door seems to make a difference because the blower is behind it.
