Good morning,

My car has abnormal function. When i turn on my A/C for first time it blows cold air and monitor at 7 degrees Celsius, but when i switch off my A/C off for some time like go out from the car and buy something from groceries. When i switch on my A/C again it blows warm air. I've check my clutch and it was engage my compressor spinning.I monitor the pressure when it blowing cold was 35 low and 220 psi high at 100 degree F ambient temperature. Usually this is happening when temperature ambient at 45 degrees Celsius. When the car rest for three hours what i observe it will give cold air again when A/C turn on again. What could be the problem?

Hello,

Is sounds like you have a temperature bleed door actuator that is not working correctly. To be sure when the system is blowing warm can you check the larger AC tube coming from the firewall (at) to the compressor to see if it is cold? Please check at the firewall. Here is a guide to help us:

Good evening Ken,
Regarding your follow up question, when it blows warm even clutch engages the pipe from fire wall which i think low pressure pipe also warm. But when my A/C blows cold this pipe also cold specially when i raise the room giving more cold.

It sounds like the compressor is going out. To be sure when the AC is not working lets test the high side pressure. here is a guide. Also can you confirm the clutch is operating when the system is blowing warm?
