    Have you guys ever dis-assembled your environmental box on the firewall?

    I did over the last two days; I think it is the first time it has been apart since it was built.

    The engine was out, and access was easy, so I went for it.

    Airflow was nearly non-existent, so I knew something was going on, but I did not expect to see things as bad as they were.

    One shop vacuuming, one giant spray bottle of coil cleaner, and a thorough hose-rinsing later, and we are back in business!

    Before:

    After:

    Instead of that black tar Ford used to seal up the halves, I used some foam weatherstripping.

    Good as old!

    Luckily with the 75-78 LTD's it is fairly easy to get at the evaporator and the heater core is probably the smartest design Ive ever seen its about a 20 minute job to change.

    Geeze... how hard would it have been to design it with an easily accessible slide in- slide out, air filter similar to the one that we use for our AC at home?

    They could have, but honestly I don't think any cars had filters back then in 1973/1974 (when the 1975-1978 style car was designed) so it probably was not even a thought.

    Modern cars almost all have filters now; the latest one I bought for my 06 Mustang had baking soda in it to control odor (Arm and Hammer branded air filter)
