Removal process was fun and easy Now the difference between the 4th gen and 5th gen is that you can pull the evap box out seperatly by unscrewing 4 screws. The 5th gen is not as simple because the evap and the blower motor unit are attached togather and cannot be separated. Just thought id give someone a heads up because i thought both 4th and 5th gen were the same setup so it took me a little longer to reinstall things.
