    2003 Escalade Air Ride; No power to compressor. New Shocks and compressor

    I replaced my rear shocks and compressor(second time) on my 2003 escalade. The first replacement compressor worked fine, but I had leaky shocks. I unhooked the compressor until I had more time to fix everything. The first replacement compressor did not work when I plugged everything in to finish the repairs. I had the compressor tested and it was bad. New compressor will not come on at all. No power to the compressor when I cheked it with a test light. Fuses are all good. I have read that I may have a bad relay. Any comments on where it is? Suggestions? I am getting a Service Stability on Message Center. Codes from the scanner are CO660(Level Control Exhaust Valve Circuit Malfunction) and CO711(Level control Air Pressure Sensor Circuit Malfunction). Any help would be great!!
