Attention: TDR Forum Junkies 
I think I probably need the blend door since I have warm air on the passenger side all the time and the system is charged. The Re-circ door seems to be partially open since it doesn't blow hard, it does ice up in Re-Circ mode after 30 minutes. I can't separate the floor from the windshield in defrost or floor modes... So, I read the heatertreater site and the quotes below have me looking for clarification... .
"4. Mode Door 2.
a. When mode door 1 is set to divert air away from the vents and into the second stage of the system, door #2 chooses whether air goes to the defrost vents to the windshield or out through the floor vents in the passenger and driver’s side footwells. Failure is indicated by an inability to choose between defrost and floor.
So, in my case mode door 1 works stopping air to the dash vents and it blows air to the windshield and floor, I can not separate the floor from the windshield. Does that mean #2 is stuck open?
b. This door turns out to be the most difficult to replace. In order to replace the door, the dash panel has to be removed. It’s still better than the dealer fix because you don’t have to evacuate the AC system, drain the radiator, and remove the plenum box. But it is more work than the other fixes. When this door breaks, it falls in the down position, blocking the floor vents and diverting all air through the defrost vents. From a safety standpoint, this is good since you’d most likely rather have a clear windshield than warm feet. We suspect that a large percentage of customers will just leave this door unrepaired. You will have heat through the dash vents and to the windshield, just nothing to the floor. It’s inconvenient, but you’ll have to make the determination if warm feet are worth the extra work to fix the door. An extra pair of socks is easier. "
I'm still getting air to the floor, yet I can't turn off the air flow to the floor in defrost mode so, does this hard to replace door need replacing?
From what I can tell I should get the 4 door package and just do them all if I want it to work right again... Right?
At least these metal doors shouldn't break again right? It appears this fix is relatively still new.
