thermo switch or temperature sender on a 4d56

BTW. The story pala is that while I left the car idle for around 20 minutes naka ON ang AC pagbalik ko I heard sa soft leaking sound and a sudden soft blow (parang gulong ng kotse na leak)
and may nakita ako usok sa hood. Pinatay ko agad yung engine then upon opening sa hood wala na ako makita na umuusok. Kinabahan ako kasi akala ko baka nag overheat yung engine ko.
After a while pag ON ko nag start naman yung makina and that is the time napansin ko wala ng lamig yung AC tapos yung compressor din di na umiikot.

Hirap kasi maghanap dito sa area ko ng magaling mag diagnose or mag ayos.

sounds like the classic aircon freon leak. and it is probably not the evaporator under the dash.
car aircons are usually de-cajon.
any decent car aircon shop should be able to help you.
sana mura lang ang pa-repair or replace nang leaking part.
