I found this out by mistake today. I washed my engine then started it right away to help dry things up while I washed the rest of my truck. I noticed while washing around the door openings, window openings and door handles that I was getting large amounts af bubbles building like a kid blowing bubbles. What was happening was I had the interior blower fan on HIGH and the inside of the truck was pressurized with the air leaking out around the doors, windows and door handles causing the soap to bubble there. It was like checking a tire for leaks with soapy water.
