Air Suspension Ride Height Sensor

[Joe]

Could someone take or point me to a picture of a working Ride Height Sensor. Also, can I assume that the sensor should show signs of being moveable by hand?

I'm finally getting around to troubleshooting my Service Air Suspension Code and suspect the ride height sensor. Not quite ready to give up on the air bags and in fact the one's in my truck seems perfect. Compressor also seems to be functional (at least to the rear hose hook up). My ride height also seems fine with no signs of deflation at all. The only noticeable issue is the ride height system will just continuously blink when pressed with no compressor run. Figure its either electrical or the sensors themselves. It does appear that the previous owner sprayed an underbody protector all over the sensors so I'm thinking they are frozen solid.

Thanks
