maybe this

no klick klick it just seems the pump just keeps going but does not click off and the lights flashing like mad. the fuse is ok and not blowing the blue and yellow cables are ok. I can only think that the 2 valves are not working allowing no air in the air bags...........................answers please

The easiest way to check if there is a valve problem is to disconnect the airlines between the compressor and the valves. If you get airflow there you can connect that line and disconnect the lines that go from the valves to the airdampers. If the valves open you will get an airflow there. If not disconnect the elecrical connector to the valves and with a multimeter check that you get 12v on the connector on the cable. if u have 12v on the connector it surely is the valves.

But it could also be the exhaustvalve that got stuck in open possition. You will then hear air escaping from that valve

Got to go
