My car AC is weird in that sometimes it works and sometimes it doesnt. Sometimes I turn it off and back on then it picks up. Sometimes when I start the car it works perfect. But more recently it’s been getting warm and not cool at all. I have yet to gone through a full diagnosis. But my assumption is the compressor (based off a lot of youtube and google). Because just this April I took my car to a friends shop and he drained the freon and pumped more in. What steps should I take to diagnosis this problem?
My thinking of order of operation.
Check for any leakage (not sure how to do this)
Check the compressor (I assume try rotating the gear to see if its locked up)
Check the clutch. (Not sure with this one again)
And that’s all the checks I have. And yes I know to drain the freon and to suck out any moisture with a vacuum. Any can anyone check my work or any advice? Thanks!
