My windows fog up on the inside but I can't really smell anything. I don't see any leaks in the cabin either. Anything else I should check?
How hard or EASY is it to change the heater core? I'm hoping it won't require me to take it to the shop. I've changed one in my old '83 Mustang years ago.

Thanks for your help!

The fogging up certainly suggests water/moisture in the cabin, but IIRC a leaking heater core would dump coolant which you would definitely smell. Do you have any leaks into the cabin - perhaps a wet smell after a car wash or rain? Do you sweat profusely LOL?

Replacing is by my standards definitely a DIY job - but according to the manual it looks to be a few hours.

1. Drain coolant
   Using the special tool, disconnect the coolant hoses from the heater core
   Remove the floor console
   Remove the rear footwell vent air ducts
   Remove the footwell lower trim panel
   Open the glove compartment.
   Remove the footwell vent air duct; Pull off the hose.
   Close the glove compartment; Remove the footwell trim; Remove the left-hand and right-hand retaining screws
   Remove the accelerator pedal; Disconnect the electrical connector
   Detach the rear steel clip NOTE: Take care not to damage the seat when detaching the clip
   Remove the left-hand and right-hand in-vehicle crossbeam bracket
   Remove the heater core air duct housing
   Remove the heater core retaining bolt.
   Remove the heater core
