Yes, It may not easy if you dismantle first time,

you might break some plastic parts.

need to remove the 2x screw on top portion,

center console need to adjust abit in order to make some space to pull the aircond assembly out.

Red Color = 2x screws you need to remove.
Blue Color = 4x clips to hold the aircond switch in place, you need to pry it out.
Green Color = these two portion connected to your center console.
Yellow Color = 4x screws type is Sanden, 3x screws type is Patco, the main connector also different.
Both brands not interchangeable.

Hope this helps.

after you removed the 4x yellow circle screws on my previous photo,

the PCB and aircond knobs will separate from the housing.

after you remove these two yellow cicle screws also,

flip over,

you should be able to see the aircond knob's screw as well,

remove the aircond knob's screw, you will see the contact point/leg I mean.

becareful becoz the contact 'leg' is very thin, you might be accidentally bent it.
(I forgot to take photo on this portion, after pasang balik only realize .... )

the knobs went inside?

must be the screws holes holding the PCB to housing broken. (same as mine)

the plastic holes is too fragile.

You not able to remove the aircond assembly is because it still connected to the Green Circle portion as I mentioned earlier.

I think your case need to figure out how to remove the center console first..
