Dam Air Suspension

[HumminNBoatin']

The compressor is under the truck in the back. If you lay under the rear of the truck you will see a steel plate in the center rear of the truck. The Compressor Assembly is mounted on top of this. Your truck will not pump up the suspension if any doors are open. So Start the truck, close all the doors and I bet you hear it start running.

If your compressor fails to run and your fuses are seem to be fine replace the relay. Its located in the engine compartment toward teh bottom of the firewall on the drivers side. Its a small grey box. You can pick these up pretty cheap.

Sounds like you have a leak in the system. Odds are its just aging bags. Squirt them with soapy water and see if they make any bubbles. They usually leak where they fold over the cup. Replacing the bags is easy. In fact pretty much self explanitory.
