If I jumper the hot power to Compressor it's runs,
but seems the voltage doesn't pass thru the relay.
i'm not getting any voltage on the coil side of the relay, not sure where it is fed from
Do you
have the same problem?

TEST R: COMPRESSOR RELAY SHORTED TO GROUND OR OPEN CIRCUIT 1. Check Relay Connector Disconnect air compressor relay 4-pin connector. Relay is located front center of engine compartment. Check connector for corrosion, bent pins and damaged wires. If connector is okay, go to next step. If connector is worn or damaged, repair as necessary and repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . 2. Check For Open Circuit Measure voltage between ground and Light Blue/Pink wire at relay connector. If battery voltage is present, go to next step. If battery voltage is not present, repair open and/or short in Light Blue/Pink wire between power distribution box and relay connector. Repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . 3. Check Ground Circuit Measure resistance between ground and Gray wire at relay wiring harness connector. If resistance is less than 3 ohms, go to next step. If resistance is 3 ohms or more, repair open in Gray wire between ground and relay connector. Repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . 4. Check For Open Circuit Disconnect Vehicle Dynamics Module (VDM). VDM is located in trunk, behind package tray. Disconnect VDM 60-pin connector. Install Breakout Box (007- 00033), leaving VDM disconnected. Measure resistance of Dark Blue/Yellow wire between breakout box test pin No. 35 and air compressor relay connector. If resistance is less than 3 ohms, go to next step. If resistance is 3 ohms or more, repair open in Dark Blue/Yellow wire. Repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . 5. Check Circuit No. 430 Measure resistance between ground and terminal No. 60 (Gray Wire) at breakout box. If resistance is 3 ohms or less, go to next step. If resistance is 3 ohms or more, repair open in Gray wire. See WIRING DIAGRAMS . Repeat ON-DEMAND SELF TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . 6. Check For Short To Ground Measure resistance between test pins No. 35 (Dark Blue/Yellow wire) and No. 60 (Gray wire) at breakout box. If resistance is 10,000 ohms or more, go to next step. If resistance is less than 10,000 ohms, repair short to ground in Dark Blue/Yellow wire. Repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . 7. Check VDM Connect VDM to breakout box. Hook-up New Generation Star (NGS) tester. See EQUIPMENT HOOK-UP under TESTING & DIAGNOSIS. Rotate dial (on scan tester) to menu item DIAGNOSTIC DATA LINK, and press trigger to select. Select VDM-VEHICLE DYNAMICS MODULE. Select ACTIVE COMMAND MODES. Select AIR SUSPENSION CONTROLS. Command COMPRESSOR ON and OFF. Measure voltage between test pins No. 35 (Dark Blue/Yellow wire) and No. 57 (Dark Green/Yellow wire) at breakout box. Battery voltage should be present with compressor off and less than 10 volts with compressor on. If voltage is as specified, go to next step. If voltage is not as specified, replace VDM. Repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . Adjust riding height. See RIDING HEIGHT under ADJUSTMENTS & INSPECTION. 8. Check Air Compressor Relay Reconnect relay to wiring harness. Disconnect air compressor connector. Command COMPRESSOR ON and OFF as in step 7). Measure voltage between Purple/Orange wire and Black wire at air compressor connector. Battery voltage should be present with compressor on and less than zero volts with compressor off. If voltage is not as specified, go to next step. If voltage is as specified, no problem is indicated at this time. Fault may be intermittent. See WIGGLE TEST and SEMI-ACTIVE RIDE CONTROL under DIAGNOSTIC TEST MODES . 9. Check Circuit No. 417 Turn ignition off. Disconnect air compressor relay. Measure resistance of Purple/Orange wire between air compressor connector and relay connector. If resistance is 3 ohms or less, replace relay. Repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE . If resistance is more than 3 ohms, repair open in Purple/Orange wire and repeat ON-DEMAND SELF-TEST and PNEUMATIC TEST under DIAGNOSTIC TEST MODE .
