Hello everyone;

recently I repaired all the AC system (Changed compressor, cabin filter, o rings, hoses, recharge refrigerant etc). in the night, morning, afternoon is like a freezer, but in the most hot hours the air conditioning is not working. i noticed that the compressor begun to turn on and turn off continuosly and in the center vents I hear a noise.

what can be the problem?

What Could It Be?

Jaun,


Your problem could be one of many. In order for someone on this
forum to help you, I recommend you follow these instructions:
1. Clearly state what year, make and model you are discussing
2. What were the original symptoms that drove you to perform all
the component changes?
3. List some facts like: Did you evacuate the system before charging it
with Freon?
4. How much Freon did you add to the system?
5. What is the pressure of the gas when the car has been sitting and also
note the temperature of the air outside the car.
6. With the pressure gages attached, what are the hi and lo port pressures?
7. Do the fans in the engine compartment come on when you switch the AC
to the on position?


With a few more facts, someone here might be able to venture a guess as
to what might be going on with your AC system.


Regards,
Paul
