I washed my car at the jet wash and while i was driving back home my son noticed bucket loads of water coming into the passenger footwell. I got home to try to see where it was coming from but to no avail. I put the heater on blow into the footwell to try to dry it out and my heaters dont blow no more but there is still heat coming from them. I dont fancy taking it into the garage for them to tell me some rubbish that the whole heating system needs replacing but i get some idea of you guys in the know. The car is a C200 elegance on a 1999.
