Looking for your knowlege on this box removal...

I am almost done with the removal of my HVAC box. Im replacing the heater core and evap core. I have all 5 nuts off the studs and the A/c and heater lines disconnected. i have the small vacume tube disconnected from the t-connector.

the box is getting hung up on something when i try to remove it. I am pretty sure it is this hose seen in the very center of the photo below.

any idea what it is or how to remove it??
looks like it should just pull out but i dont want to force it without knowing i should.

THANKS!

 

That's the hose for the rear window washer fluid. It shouldn't hold the HVAC Unit. The hose goes through the firewall then makes a right turn and goes under the passenger footwell carpet, then back to the cargo bay hatch.


Is that the HVAC Unit drain hose I see there with the blue dot on it? That should be removed.
