The Passport had mice living in the blower box and the AC Core was all clogged up with junk. The Heater Core had a leak so the previous owner just bypassed the feed and return instead of fixing it.
In this episode we finally get to work. Removing the dash and all climate control systems, taking everything apart, cleaning it up, and reinstalling with the dash from the 98.
This was quite the undertaking. Had I had someone show me exactly how to do it before I started I would have saved a bunch of time. I hope this can be that video for you.
Major Lessons Learned: When removing the Dash you should take the wiring harness that is attached to the dash with it. When removing the climate boxes, you should start with the AC Core box, then remove the ducting before finally getting the Heater Core Box out.
Otherwise this is a pretty strait forward process. I made a bunch of mistakes and waisted a bunch of time where I didn't have to. Hopefully this video helps familiarize you with the process so you can be more efficient with your time.
