Need Help - '95 Suburban Tilt Dash Evap

Model: Suburban
Engine Size: V8
Refrigerant Type: 134a

Hi Guys!

I'm having a real bear of a time on this suburban and I'm at my wits end. It's a '95 4WD and I'm currently doing the front evap core. Mitchell states that you can tilt the dash and then remove the airbox assembly. Where I'm at is the dash it tilted, every airbox bolt I could find on the firewall has been removed, the airbox itself is loose and able to move around but I can't seem to get the damn thing out. It's as if it's still stuck in place?

The airbox can be wiggled around top to bottom and it looks like everything is moving freely. Yet, we can't get the damn thing out. It seems that the bottom is loose then the top - that is to say, we can readily see the evap & heater core fittings move in & out when wiggling but the upper evap line doesn't move much.

Is anyone out there familiar with these tilt dash evap removal procedures? Am I missing something common? I wish I could just remove the entire dash assembly so I could see what I was doing more clearly...

Help!
Soon to be insane :-o

With help of a fresh set of eyes we found out that there is one bolt that in installed from the _inside_ that goes through the firewall. It's nearly impossible to see and is about 5" down and roughly inline with the far end of the battery. Once removed the whole assembly started to come out.

There was still not enough room to remove the air box and the final part of the solution was to remove one side if the dash off the 'tilt assembly' using a big hammer to 'reshape' the assembly. Once one end of the dash was removed entirely there was enough room to remove the airbox.

BTW, Mitchell said nothing about the single bolt from the inside and also said that tilting the dash was enough to remove the airbox. Maybe for them but it wasn't for me :-0
