Hello I drive an iswara and recently I brought to a workshop to add gas because the air cond was not cold. After adding gas and then one or days later I had to go back to the workshop because the aircond power is so low, imagine when I m sitting in the car sweating even the aircond is on. so I check with the mechanic and then he use something to test, and check the pressure is 70 degree, is that normal he told me that suppose to be 20 to 30, in such cases I need to change the compressor, and he say the denso compressor will price at RM500, is that true? Need Sifu advice.

It wasnt the compression problem it was the mechanic that decided to add extra gas which cost the problem. Another thing I would like to know if the aircond air is not strong, any idea what is the problem?
