So my car stopped putting out cold are about a month ago. I realized something was wrong and not wanting to burn out my A/C clutch or just break the compressor in general, I’ve tried to keep the A/C off.
I went to get a refrigerant refill kit and when I read the pressure, it fluctuated up and down. Did some research and found that if it’s fluctuating, it’s low. However, when I actually started refilling it immediately hit red on the gauge, whether compressor was engaged or not. The pressure fluctuates as the compressor engages and disengage. Here is a video: https://drive.google.com/file/d/16Ln0tAtL12fGy464ZrV1jmjVnQrH5vJS/view?usp=sharing
I say when the compressor is and isn’t engaged for reference. I should note that RPM drops and power loss happens exactly when the pressure drops and the compressor is engaged. Engine visibly shakes and compressor sounds like it’s struggling when on.
Any help is appreciated, thanks!
