You are probably right, but let me try this on you (forgetting about fuse 20, etc.)
1. Will the system come on when the back end is at it's lowest point and no one in the truck? Mine does! But the back end does not raise.
2. Is the height adjustment switch in the back supposed to send a signal to somewhere tell the air compressor that the air bags need air? With the ignition off I get no power at the switch so where would I get power to the switch to tell the compressor the bags need air?
3. The compressor does come on randomly (I believe this might be for the front shocks), and the solenoids do activate at the air bags. I have not disconnected the air lines to see if air is being pumped back there yet. I will do that in the morning.
If the air bags are empty, I will not be able to make bubbles.
4. I have the truck jacked up and the height adjustment switch disconnected so I can activate it manually. Right now, I can not get the compressor to go on using the switch.
I am wondering about that relay up in front on the right side near the bumper. Some people on line say that has a tendency to fail?
Thanks for your patience.
