I have a 2000 Mercedez Benz and today I noticed that on the passenger seat (in the front), water has been dripping onto the floorboard. This dripping water occurs when I’ve had the AC on. Does anyone know what is the cause of this? Any ideas on how I can fix the problem?
Thanks for your time,

Sounds like the heater/A/C box drain is plugged up… The water is supposed to drip outside. Look for a rubber drain tube under the passenger side footwell near the firewall. Carefully clean the tube out with compressed air or a coat hanger…
Yip - you were right. The tube was clogged - thanks so very much! You’re getting a raise!
