I have a 1999 4.6 HSE. Every 3 months or so I get "EAS Fault". The only way out is a dealer reset, If I don't it drops to the bump stops after about 200 miles without further warning. Error message is "pressure switch not changing state" I have changed pressure switch, air dryer, relay (in relay box). No obvious compressor or valve block problems. I have heard of other RRs being traded in because of failure to find a solution. Surely there must be an answer! Any other ideas please?
