There is a slow leek in the lines to the system. SO after sitting a while my rover will be setting all the way down, after I started it up I was able to hear the compressor com on and after sevral minutes the system we fill up in the rover would go up. the other day I wanted to go for a ride, I started it up and waited only this time it never did go up. I listend for the pump to come on and could hear it come on but after just a few seconds it would go back off. I was able to chec the relay and the fuse under the hood they both checked out fine. Is there another relay or sensor some where else that I am missing?
