When I was detailing at one of the dealerships I was working at, one of the sale's guys gave me $10 to do a very quick wash before he showed a car that just showed up on the lot. It was used, but I don't remember if it was a Camry or Maxima. Anyway, he came in with the car, left it running with the AC blowing and jumped out to help.
When we hit it with the soap and the wash mitt, bubbles were coming out EVERYWHERE around the passenger compartment - even from the door locks! The backglass was replaced at one point, but it wasn't sealed correctly on one of the corners - bubbles.
If you ever get your autoglass replaced, and it's urethaned/glued in, wait for everything to cure (24-48 hours) then do the soapy water test to find potential leaks.
