Car is a 1997 E320 with 130000 miles
I have noticed that when I turn on my heat the lower part of my windshield fogs up then clears up. Is my heater core leaking? I don't feel any fluid leaking inside the car. Does the heater core have a drain going outside? I do smell the sweet smell. When I turn on the a/c I also here the refridgerant moveing in the system. Does my expansion valve need to be replaced?
