I started to work on getting to my heater core Thursday evening. I was in a hurry to get things started, and didn't have a camera or photographer handy so no pics so far. I'll try to take pics as I reassemble and make a new Post describing the process.
A couple of notes.
Remove the radio front center bezel and center console before disconnecting the battery as the shift lever is in the way when in the PARK position. The gear selector will not move from Park with the battery disconnected. (How would you put the vehicle in NEUTRAL to coast the vehicle with a dead battery if it is in PARK.) The key will not turn off when the shift lever is in anything other than PARK position.
Put a small paper clip in the zipper slider when unzipping the Parking Brake cover. There is a back to the radio compartment, so you can't even see the heater with the radio removed.
Disconnect battery to power down the Airbag system.
The first part of disassemble is pretty straightforward. Bottom Foot Guards - 2 screws and Plastic Molly Bolt type inserts on each side. Glove box opens and drops down - slide to right. Panel under steering wheel - pry top down and slide to left to remove.
Side A column panels pry out - be careful not to damage the side curtain airbags.
Removing the top panels behind windshield by prying the rear edge is kind of tricky. Pictures speak a thousand words. Remove drivers side first as it is over top the passenger side panel in center of dash. Wire disconnect on left side of drivers side.
Note: Left & right side speaker covers and center coin holder (directly behind windshield defrost vents) are held down by screws under the top panels.
I didn't remove the passenger side airbag - it wouldn't come out.

About 6 hours work so far, but lots of trial and error - Flying by the seat of my pants. Through the glove box opening, I can see the 2 lines and O-ring couplers coming from the heater core.
Presently, I'm trying to remove the steering column cover without breaking and next the steering column itself.
I'll keep you posted on my progress.
