My audi a4 was sitting in my drive way for about a week not moved or opened. It had snowed a good amount during this time period. When I went to go start my car up I noticed there was frost built up on the inside of the windows and a good amount of ice built up on the rear passenger side floor. Is this a normal thing seeing as the car was sitting for so long? Someone please help thanks

Clogged sunroof or door seal trays. Get an aircompressor and blow them out

open your sunroof and look in the corners, you will see a drain in each corner these are what you want to clean out.

Pics are not going to help you, everything discussed here about clearing the drains only pertains to cars that have a sunroof, if you do not start checking your door and window moldings/seals. Have someone drench your car with a hose with you inside and see if you can see where your problem is coming from.

you need to check your fresh air intake vent in the engine compartment. the drain over the filter often breaks or becomes clogged. then water flows into the car through the HVAC system and concentrates at the lowest point--the rear seats.

What does that fresh air intake vent look like? Is there a link to a picture of it?
