If you are receiving a BL-OC error code on your Air Lift WirelessAIR Compressor System for Air Helper Springs # AL72000 which is no longer available from the manufacturer, that is indicating that there is a blockage in the system.

Start by tracing the air line from the compressor to the air bags and check for kinks or areas where the line might've become loose.

Next, check that the compressor is receiving 12V by using a multimeter like # PT89ZR and check the leads coming off the compressor. If you are receiving 12V coming off the compressor, continue by checking that you are getting 12v at the ignition source on the relay. This should be on terminals 86 and 30 on the relay.

If the compressor runs when you give the relay a ground on terminal 85, then the manifold might be bad and is not sending a signal. If the compressor still doesn't run, then it would sound like the relay is bad.
