Question about 2003 Toyota Celica
Hi S, The fan is not controlled through or by the ECU. I suggest you check the connection to the fan temperature sensor. If it is disconnected the fan will operate. Refit the connector and make sure the connection is making good contact. If the fan continues to run make sure that the relay is not fused and that it is operating correctly. Regards John

Was what came out smoke or vapour....Sounds as if you may have been using it on auto and if so just have alook at the LED on the selction button....is it flashing out a code or is it a steady light?....It could be the expansion valve or it may be the electronic control unit....If you have a code that's showing....count the number of flashes it gives....thats the fault code number....Get that info first, so that we can go on from there....

Can you hear you A/C compressor kick off and on when you press the A/C button slowly off and on (off 3 sec, on 3 sec, repeat)? If your R134a i charge is low, system pressures can drop and the system will stop functioning to protect itself. It may need to be properly charged. The dealer or a service center will want to check the car, then charge it and add dye to diagnose it. This is normal. They usually request that you drive the car, use the A/C and come back in to check and see if the dye leaked out anywhere. You can verify that your car has r134a on the factory sticker under the hood or near the radiator. DuPont has a small can of SUVA or 134a at most parts stores with oil and dye. You could put it in yourself if you feel comfortable doing so and you follow the directions. Good luck.

I had the same problem on my 2004 Corrolla and ultimately it only worked on high. The dealer charged me $45 diagnostic fee and almost immediately told me it was a part called the blower resister. They knew the answer right there and then but only realesed it when I agreed to pay the diagnostic. They charged me 179.00 to fix the AC and later I found out the part cost $8.95 and a novice could have replaced it themselves.
