I have an odd question. I have had a VW Beetle since 2002. This year, I am getting frost on the inside of the windows. I've checked for moisture in the interior of the car but can't seem to find any. I've checked the doors, sunroof, and hatchback and there doesn't seem to be moisture coming in there either. Yet on cold mornings, I have to scrape the windonws on the inside. Any thoughts on what might be causing this?

Thank you.

Check to see if the A/C evaporater drain isn't plugged on the heater box. Any trapped water there will evasporate when the heater is on and frost up the windows over night. Also, check the door drain holes in the bottom of the doors. Water held there can do the same thing. Hope this helos.

Thank you for the reply. I will check the drain holes ad the bottom of the doors. As a follow-up, where do I find the A/C evaporator drain?

Thank you for your reply.

Condensate drains should be coming from the bottom of the heat/ac box. look for a rubber tube, or a plastic port to the exterior.

My problem still persists. I have received a number of suggestions but none have proved to solve the problem. My search continues ....
