Problema con aire acondicionado

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?

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.)

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

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.
