Possible heater core??

[Eckl]

Have an issue with fogging windows. Not drastic but annoying enough. Can't smell coolant, and never have to add any. Floor not wet with anything, but windows continue to fog. Windshield is manageable with the defrost on, but the side windows and rear windows suffer major fogging otherwise.

Any ideas?

Take a door panel off of one of the worst doors and see if there is standing water in there at the bottom!
