Question type: General

When I drive it everything is good. The compessor fills up the rear and when it sits for
about 30 minutes it lowers about 3 inches. It was all checked out but cannot find what is
going on.

Recheck all air line,s there is a leak somewhere in the system.

Slow leaks are hard to find,soapy water sometime,s help,s you find the slow leak,s.

Air bags are a high fail on these vehicles, get the system pumped up and spray the bags down completely with soapy water and look for a foaming where the leak is. The other place the system leaks is at the compressor filter can connections under the hood.
