opened the door of my eg yesterday and it was very damp in the drivers side footwell,
dried it up and same happened this morning.

any ideas on where it might be coming from?anyone have the same problem??
was told it could br from the heater pipes?

 

Was it raining?94

 

ya heavily both nights!

 

Then you have a seal leak someplace, windshield maybe or at the fresh air intake.

Unlikely to be your heater core, unless that "dampness" is engine coolant. 94
