Checked my Haynes manual an didn't see anything check around ur blower motor under the dash (big round thing with wires coming out of it) if u can't find it there trace ur AC lines and see where they go through the firewall and it should be just after that

 

i just checked and 2 lines run thru the very top of the firewall
near the middle of the glove box. so i took the glove box out
and still didn't see anything like in your picture. the big round black
thing i'm thinking is the blower had nothing behind it. i'm just going
to take the hole dash out.

edit: looked it up in the service manual duh

"The evaporator, located in the
HVAC housing on the dash panel below the instrument
panel, is cooled to temperatures near the freezing point.
