Town and Country A/C Evaporator Removal Question

I'm not sure if it's bravery or stupidity, but I am tackling the infamous a/c evaporator replacement job on my 2001 T&C. I have read all of the info I can find online and printed out a couple of checklists I found on the 'net, but they gloss over the bit where I'm stuck.

Specifically, I have the dash lowered and the heater box exposed, but I'm apparently missing something that still needs to be loosened or whatever because it won't budge. I have thus far removed removed the following -

* the three nuts on the engine side of the firewall

* disconnected the two heater hoses

* disconnected the lines at the expansion valve plate

* one bolt at the top of a bracket above the box inside the vehicle.
The bracket goes down the middle of the box and two screws at the bottom of the bracket connect it to the box.

The heater box still won't budge and I don't want to put much pressure on it in case there is something I've overlooked.

The checklists I have say this in reference to removing the heater box -

"Disconnect the two upper mounts from the upper reinforcement and the lower mount from the tunnel."

Where are these upper and lower mounts specifically? I'm not seeing them and the checklists I have don't provide photos.

Any guidance would be appreciated.

The dash needs to be out not lowered. It's a good idea to have it out of the car so you don't poke holes in your seats moving it around. Did you take out the steering column? Also take some pics here and there, so you remember where it all goes back in.

Thanks, but the dash is already out, it's the heater/a/c evaporator box I'm having an issue with.

The leak was diagnosed to the evaporator by charging the system and using dye. The dealer quoted $1500 and two independents between $1300 - $1400. From what I've read and been told by the mechanics I talked to about this problem, the evaporators front and rear were a fairly common issue on the Chrysler vans of that era. I've also seen posts on forums all the way back to 2004 talking about leaking front evaporators on 2001's. The 2004 thread I saw was reference a 2001 T&C, only three years old with 46k miles, so hence out of warranty.

Let us know how they turn out then
