The air blowing through my AC vents smells like pee when I first turn on the AC. I can smell the pee smell for about a minute and then it seems to go away even with the AC still running. I do not have this problem when I turn on the heat.

Good advice. Another thing you may want to check is your windshield wiper fluid. Some windshield wiper fluids have ammonia in them. Urine is mostly ammonia.
