Can't tell you much about the heater in the Celica.

A replacement matrix can be obtained in a wide price range depending on where it is made and who supplies it. Best to shop around and buy antifreeze at the same time.

Generally cars that are designed for LHD and being used for LHD have a better heater matrix access. Japan drives on the left and cars destined for driving on the right probably have a production conversion, changing pedals and column, etc. but not such things as the heater matrix access - if it had one...

Those that don't have access mostly need taking back to the stage in production where the heater unit was fitted.
That can be major work and a repair manual is almost essential.

hello, it could that the timing belt is worn and slipped on the pulleys so I would go there first and make sure the cam timing is aligned and inspect the timing belt.

Here are the most common causes of idle surge, stalls at stops, slow idle speed, erratic idle speed, rough idle and engine hesitation (and other problems), it is in most cases the idle speed control air-bypass valve and or throttle valve and upper intake, these area's get full of gunk and combustion residue over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake

Faulty engine temperature sensor ?? On a cold start the temperature sensor should detect a cold engine and give a signal to the ecu to increase fuel ratio until the engine has warmed up. sounds like faulty sensor to me.

It is very easy to check an a/c compressor clutch. Looking at the compressor, you should find a wire running from the pump the wiring harness. There should be a connector where you can disconnect the wire from the main loom, disconnect it and connect a length of electrical wire to the wire going to the pump. Connect the other end to the battery positive and you should hear the clutch clicking in. If you don't, the clutch is bad.
If it does click in, you should look at the fuses (should actually look there first) and the relay if it has one. By the way, if you connect the wire as described and you hear the click, you could actually leave the wire in place and start the engine and you should feel the cold air.

Typically this is caused by a vacuum leak. So, either a hose has come off or a hose is cracked
