Occasional odor from A/C. There was a service bulletin that called for a coating be applied to the evaporator (I believe).

Consistently comes on if driven that long. No tire pressure reading when it's on, reads fine when not. They re-learned the tires, which I had tried before. Still a problem. $0 cost.
