Asked by for the 2002 BMW 530i
yes, there is a pressure switch. however, there are MANY
other likely suspects to cause the compressor not to engage. the first thing to do is to scan the climate control system with BMW software to make sure that the
control system is okay.
ok so if the control system is okay then...........
