2005 Other Lincoln Models V8 Four Wheel Drive Automatic 67,000 miles
Sometimes the battery goes dead when it sits overnight. Not always, just sometimes. The battery is new, the cables and connections are good, the alternator is fine. Sometimes after it is shut off, I can hear what sounds like a small air compressor still running. I suspect this is what is draining the battery. Any thoughts?
Could be the air suspension compressor. Is the ride height OK? Navigators have a tech bulletin about the sensor links front and back disconnecting from the control arms up front and axle in back, there is a new design link.
