2004 E.B. Air ride compressor wont kick on

[FUBAR2208]

Any idea or trick to get the compressor to kick on?

I kept the tire off and tried to manipulate the height sensor, up and down, it didn't let air in or out....although i only did one side.....wouldn't think I'd need to manipulate both sides.

The switch/module right on top/attached to the compressor gives me 10ish Volts at the plug and the module shows me resistance on the closed leg and OL on the open leg

I've replaced the struts/air bags, compressor and height sensors before and had this issue but cant remember how I got it to re engage....was messing with "something" and compressor kicked on and I was good....took awhile but got it to work.

If anyone has any ideas, let me know.

Is the air ride switch in the driver side rear panel turned on? There's also a module calibration that can be run with a high end scanner that might be required.

Do you know what module calibration it would be?

I think the compressor I got is bad.

It just gets really hot, too hot to touch but never kicks on.

Seeing if they will let me swap this for a different one.

The calibration is the process of getting the module to relearn the height sensors.

It sounds like the compressor might be faulty if it's getting hot, but not running. Sounds like it has a direct short inside.
