2003 BMW 530i Question: relay switch
Answer #1Chow June 07, 2010, 03:43Master
not too sure on the relay at this very moment but there is a pressure switch
the switch is located on the a/c pipe itself with a black plug hanging off it
forget which line is was but within the RHF area
please ensure a qualified a/c handler has evacuated the lines before replacing if faulty.
