I put in a new relay & fuses are good. pump fires up ONLY when I jump 12 volts to it. info center reads Service Ride System & I cannot get the message out. I think it takes a scanner to remove message & then perhaps the system will activate. Any opinion would be appreciated.Katshot said:OK, The compressor and exhaust solenoid are under the car together. The ELC relay is in the trunk in the #2 relay panel. The system is powered by (2) fuses, one (a 10amp) in the engine compartment fuse block and one (a 20amp) in the trunk fuse block.
