My 2000 BMW 328i a/c quit working. I have check freon and have correct pressure. I took out the a/c relay behind the glove box and replaced with new one. No changes. I jumped across the connections where the relay plugs in and the compressor kicks in and a/c starts working. I am trying to find the A/c low pressure switch to see if that is the problem. Where is the low pressure switch located or do you have any other suggestions?

Low pressure switch is on the suction line. High pressure switch is on the high side line. Follow the lines till you see an electrical connection.
