Yes. It serves to reduce humidity in vehicle.

My first guess would be the low pressure switch. It gets power from the relay.

CHECK THE SENSOR FOR PRESOR ON THE OBD FIRST, SECOND CHECK THE CLUTCH ON THE COMPRESOR

probably need leak fixed in unit or just recharge

the module is part of air bag /front steering wheel module for example is attached to a/b and is part of mounting platform in steering wheel--- also which one--

CHECK THE FUSAGE IN THE AC FUSE BOX UNDER THE HOOD.

this isn't easy and you will need special tools.  You will most likely need to have the compressor on a work bench.

Hi, you should never bypass the compresor because it may cause damage to the sistem including the compresor,even if the sistem is charged if it gets a little low it may prevent the cluth to engage to prevent damage ,be sure that you have the proper freon presure.also check the ac relay and the fuse.....good luck
