    Re: Answer the 1Million Question: Where is the air ride control relay located?

    My "service ride control" story! I will try to make this brief. Bought an 03 EXT in November 2013 with 75K on it. December received the SCR message. Using this thread, ran thru all the steps. Jumpered the relay on the fuse block under the hood. Nothing. Removed the pump for replacement. Jumpered the pump and the plug, compressor runs and pumps. Reinstalled and looked for other issues. Nothing. Finally pulled the compressor again and found the exhaust solenoid bad. Based on an earlier posting, I soldered a 5K ohm resistor across the coil connections and stuffed it back in its housing. Reinstalled the compressor and the error message went away and the compressor runs in the morning when i start it up. I know I need to replace the compressor assembly but at least I am sure of the problem. I don't plan on hauling anything as the system cannot exhaust the pressure at this point but I am a happy camper spending $2.00 to make the system work again. Thanks to all who have posted on this thread. The information was invaluable.

    I read the 28 pages of this thread, fixed broken wire inside solenoid, I have no 30 to 90 ohms resistance, nothing. Compressor runs if I bench tested, grounded blue wire at the scm connector, relay socket, relay is good. dont know what to do next. Any sugestions?.. Thank you.

    Get the codes pulled to find the culprit

    exhaust solenoid valve was the culprit, I unrolled the wire and it was broken 4 times.
