I am assuming that what you refer to as a heater "matrix" is what is known
as a heater core in the U.S. I've never run across a heater core that is
easy to replace. You may wish to remove the passenger seat to give yourself
some extra working room.

Ray, Paul,

I can confirm its an absolute ARSE of a job and requires removal of
most of the dash.

LOL! Judging by the pictures I saw of your Celica, I'd feel very safe
relying on your assessment!

I've never run across heater and evaporator work that wasn't a huge pain!

Keep plenty of anylgesics like aspirin, ibuprofin, or acetominophen on hand
for the aches and pains from your contortiouns and bandages for the finger
cuts.

lol, i think there isnt a part of my baby I've not seen naked now LOL.

Heres a writeup I found on the GT-Four (alltrac) owners club:
_____________
The secret is this, if it (heater matrix box) dosn't come out EASILY then
you havn't undone enought bolts n nuts. I did the following.

Removed Gear knob.
Removed Gaiter covers.
removed stereo facia/cupholder/ashtray thingy.
removed arm box thingy in middle (screws actually under tape holder)
removed centre column.
removed door trims that says celica
removed panel below steering wheel
removed glove box
remove middle vent with clock (just pops out)
You do not have to remove the climate control panel.

Now you will see 3 white boxes on passenger side to remove two of these you
will have to unfortunatly ungas aircon and then undo pipes from engine bay,
there are two pipes for heater matrix and two pipes for aircon.

When pipes from engine bay undone i then removed the two metal brakets that
the stereo screwed into they also act as supports for dash.
Remove ECU also.
Now you have to remove the middle white box (air con unit) and the right
hand white box (heater matrix). these are held in by about 9 bolts and there
is one behind the clock holding in the heater matrix which is a BITCH to get
to, its not exactly behind clock but its to the right behind the cable that
turns the tempreture up. You also have to detach a small rod that is on a
control wheel on the right hand side of the right box by uncliping it. These
white boxes WILL come out VERY easily if you have undone all the bolts and
nuts, if they DO NOT come out you have not undone all the bolts OR the pipes
are having trouble going through the firewall.
You do not have to open the white boxes ever so don't undo the little screws
that hold them togheter or the clips, leave them on.
Remove air con box first then the heater matrix one. You will see when you
have heater matrix box that you undo a holding screw on top of the pipes and
it slides right out.

LOL! No offense, but better YOU than ME tackling that job! I've been there
and done that, wearing a suit - it impressed the hell out of customers to
see a Japanese guy in a dark suit crawl under the dash board!

Maybe the woman in this picture was trying to get at the heater:

LOL, in a suit - no chance. Its the head-balancing-on-floor with legs
over the seat back that would do me in, bound to split the suit. Plus I
always end up with 2 extra screws and NO idea where from until 6 weeks
later when something rattles itself to destruction.

I'll share one of the tricks of the trade...

Always put spare screws in your pocket before anyone else notices and blame
the problems that arise as a result of the missing screws on the owner's
"personal mechanic" or uncle that worked on the car 5 years ago ;-)
