Hi everyone.
I have a slight problem with my air conditioning.
When I press the button to turn it on, there is a hissing sound for a few seconds, until the ac kicks in.
I should also add, there is a slight squeak when turning on the car, probably from the serpentine belt.
I say this because I did some looking and some people said that it might be the ac compressor pump.
However, I couldn’t find anything definitive.
