Problema con aire acondicionado

[jeoc27]

Hola amigos,
Le cambie el evaporador a mi yaris 2006, el cual trabajo bien por 3 dias, desde entonces ha estado presentando problemas de enfriamiento en horas del medio dia (NO ENFRIA). y al parecer el compresor hace un ruido tremendo como si trabajara sin refrigerante, luego enfria normalmente x unos minutos y luego lo mismo otra vez, evitando asi q rinde el aire. Lo he llevado a un sinfin de tecnicos y nadie me ha podido ayudar con este problema! es como si cuando hace calor se dispara el compresor. Desde ya muchas gracias por su ayuda!

[CTScott]

Si funcionó durante un par de días y luego se detuvo de refrigeración, el refrigerante debe tener fugas.

[jeoc27]

gracias por la pronta respuesta! pero de gas esta bien, pareciera mas bien que tuviera problema con el condensador por que al pegarle el sol es q produce el ruido y sopla aire caliente lo apago unos minutos y vuelve a enfiar bien! es como una falla intermitente

[CTScott]

¿Has comprobado la presión del refrigerante? Hay un sensor en la línea de alta presión que evita que el compresor se ejecute si la presión es demasiado alta o demasiado baja.

[jeoc27]

disculpa amigo, en que parte exactamente esta ubicado ese sensor?

[jeoc27]

el asunto es q este problema lo estoy presentando desde el cambio del evaporador, y si estoy seguro q este reemplazo produjo la falla ya q tengo un amigo de una terios con el mismo problema luego del cambio del evaporador

[CTScott]

El sensor está unida a la alta presión (de menor diámetro) tubería cerca del lugar donde su conectar la manguera de alta presión al probar el sistema. Con A / C normalmente no sólo puede cambiar las piezas, sino que más bien tiene que diagnosticar correctamente el sistema con un conjunto de medidor de presión.

[jeoc27]

ok amigo muchisimas gracias, voy a verificar y le estare informando del resultado

[jeoc27]

disculpen amigos, alguien sabra donde puedo reparar el modulo del aire acondicionado en venezuela?

[jeoc27]

es para el yaris 2006, es el modulo que esta ubicado por las pedaleras

Da hell ?? Lol I didn't know you can type Spanish, can you speak it?

Broder lo puedes llevar a donde lo comprastes oh cualquier tienda que venda Toyota.

My French is a whole lot better than my Spanish. I use google translate when responding to a thread like this (since my primary Spanish knowledge involves cerveza and baño)

[CTScott]

es para el yaris 2006, es el modulo que esta ubicado por las pedaleras

¿cuál es el número de Toyota en el A / módulo C? A menudo se puede encontrar utilizado por menos de $ 50 US.

¿Está seguro de que es el módulo y no el sensor de presión?

[jeoc27]

si amigo es el modulo ya que un amigo me presto uno para probar y funciono perfectamente, el numero es 88650-52371, gracias por la ayuda

[jeoc27]

if friend is the module since a friend lent me one to try and it worked perfectly, the number is 88650-52371, thanks for the help

[CTScott]

Eso es difícil de encontrar, ya que no se utilizó en Yaris para los EE.UU., Europa o los mercados japoneses. Se usa sólo en Yaris para otros mercados.

[jeoc27]

ok good, thank you very much and keep looking to see if I can get the SPF5014 integrated circuit which is the piece that has a bad module card

[CTScott]

That is a power switching and current monitoring IC. Here is a picture of the circuit board from an AC ECU that I bought from someone in Israel. I purchase a lot of parts from around the world to experiment with.

The part number is different (88650-52291), but based on my experimentation, I believe it would work for you (I tested it in a US Yaris and it functioned properly). In a worst case you could transplant the SPF5014 from it to yours.

and mount the amplifier air but still the problem that stops cooling noon, as if much of the pressure rise high! I will maintain the condenser and nothing that I will change the fan? thanks again

I would only change the fan (or first check the fuse for it) if it does not spin at all.

When you changed the amplifier, did you find a new one or were you using the one that you tested from another car?

[jeoc27]

hi, the fan turns, what happens is maybe not turn adequate power, the amplifier and again, buy it in a store toyota original, I repeat that pays enough in midday hours that here in Venezuela is where It's warmer ambient

If the fan was having problems I would expect the engine to overheat as well. Do you know what the pressure readings are on the refrigerant?

[jeoc27]

that's the problem that the car shows no signs of being overheated, but somehow ups the pressure of the air conditioner when the weather is hot and the compressor stops working and hot air is thus

If the pressure is increasing enough to shut the system down, then chances are that it is overfilled.

[jeoc27]

you know how must be the pressure so I can check that?

[jeoc27]

la alta y la baja presion, por favor

[CTScott]

22-36 PSI on the low pressure side (30 PSI is ideal) and the high pressure side will continually fluctuate between about 180 to 225 psi depending on the ambient temperature.

Also, the freon charge is only 330 to 390g (11.64 to 13.76oz.)

[jeoc27]

hello friend, we measured the pressures and low this from 32 to 20, but the high pressure, it seems strange that in 120-130

[CTScott]

hello friend, we measured the pressures and low this from 32 to 20, but the high pressure, it seems strange that in 120-130

Did you measure it with the engine running and A/C on? If the compressor is not running the pressure will be low on the high side.

[jeoc27]

if the compressor is turned on in the low speed and reaches 30 to 22, but varies between 120-140 as high max

[jeoc27]

with the low pressure compressor is turned on at 30 psi and 22 psi reaches speed but high ranges between 120-140psi at most

[CTScott]

with the low pressure compressor is turned on at 30 psi and 22 psi reaches speed but high ranges between 120-140psi at most

Then you have a leak on the high pressure side or a bad compressor.

[jeoc27]

that bad, hopefully not the compressor, just take a check today but the car does not fault jajajajajajajjaa! seems like when you go to the doctor for pain and go beyond all tests well, but according to the technician good psi are good! really do not know that failure will be high pressure because it is, you will know how this is the fault when bad poa valve?

[jeoc27]

This is another post that I found that has the same fault as mine.

air conditioning failure

-------------------------------------------------- ------------------------------

hi all.

I have a 2005 yaris two months ago because they changed the evaporator was leaking gas.

After the change when the car is parked for a while and take a walk again, the air stops cooling, turn it off a few seconds and turn it again when it works perfectly.

While the car is running it works perfectly.

agradecere suggestions.

greetings,

Frank.

Looking at the Service Manual in regards to the expansion valve, I found the following, which sounds a lot like your problem.

Condition:
Air conditioning system periodically
cools and then fails to cool.

Cause:
Moisture in refrigeration system
freezes at expansion valve orifice,
causing temporary interruption of
cycle. However, when melted, returns to
normal condition

Diagnosis:
Receiver dryer oversaturated
Moisture in refrigeration
system freezes at expansion
valve orifice and blocks
refrigerant circulation

[jeoc27]

ok, I'll send to the pipe with a clean sweep, make empty and then load the new gas

[jeoc27]

hello me again, change the compressor and the problems persist, the technician told me that the fault current appears because it works well and seems to be working at the time of the cold decreases because the lower the voltage generator that sends and causes the lower fan speed and thus their high blood pressure to rise and leave to cool, is this possible?

It could be that the pressure switch is bad. It would be great to get a Toyota Techstream tool connected to your car to read the error codes and live data from the AC computer.

to remove the exhaust air begins to chill well

hello friend, the voltage must receive the compressor?

[CTScott]

hello friend, the voltage must receive the compressor?

The compressor gets 12 Volts on the green wire to engage the compressor.

[jeoc27]

hello, condenser and evaporator cel my yaris and now cooled cooling well but leaves soon after and note down the pipe is not cold but rather sweaty

[jeoc27]

Hello, you change the condenser and evaporator compressor yaris and now my cooling fine but stops cooling soon after and note down the pipe is not cold but rather sweaty

Buenas tengo un problema tengo un yaris sedan 2007 cuando el carro esta parado no enfria el aire pero si lo acelero un poco empieza a enfriar alguien sabra el por que? Me disen que puede ser la poa pero que quisas no! Alguen que me pueda ayudar
