Took truck to advanced auto they put diagnostic on truck once they were done tried to leave gauges, lights, and radio went crazy...truck died and they jumped truck, once jumped same thing happened backed...
Hello, From the symptoms you gave, I would say the Air-ride system is part of the problem. You also have a secondary problem caused by the constant drain on your battery by the Air-ride compressor. This is activating the Battery monitor system which is trying to preserve the charge in the Battery.
There are several things you can do. For the Air-ride, you can use soapy water in an old spray bottle and go under the vehicle and mist the suspension bags and air line connections. If you see bubbles where you sprayed or hear escaping air, replace the part that is leaking. Or have the Expedition taken to a place where a Scanner can be used on the Air-ride system. Sometimes Autozone, Advance, or Oreilys will have a better Scanner that can do the Air-ride module. If not, you need a Dealer or Independent shop having such a tool.
The Air-ride system depends on all doors and the rear Cargo lid being closed before the Expedition will pump up the rear bags. If the rear lid is not closed or if any door jam switch is broken, the Vent-valve(Dump Valve) will not close and the air will escape. If you can hear escaping air after following the air lines to the Drivers forward front fender, then the Vent valve is probably stuck open.
The other problems you were experiencing could be due to a bad Alternator and/or the Battery being too low. The Battery minder will disconnect the charging system AFTER a jumper start has been done. I have clients who lost the charging circuit at 70MPH, just because the Battery was too low. Once 3 to 5 minutes has passed, the Battery monitor can disengage the charging circuit without warning.
Charge the Battery above the listed 12 Volts, a good charge is 13.2 to 13.6 Volts. When this is done, the charging system will work again, unless the Air-ride compressor is drawing too much juice.
The Battery needs to be disconnected from the vehicle cables but can be charged on the vehicle.
There is a toggle switch under a plastic cover in the rear cargo area. You can shut off the Air-ride but it is not recommended to drive it shut off. All of the news is not bad, one single sensor or switch can fix the entire system. Getting the Air compressor to stop running has a good possibilty of fixing the power drain for good.
This is why I mentioned Scanning the Air-ride module. You have a big time/labor savings when the Scanner identifies which wheel is causing the problem or which doorjam switch is bad. I hope my solution is helpful to you. Be careful when the Air-ride system is pressurized as it is a Hazard to jacking the vehicle and wear safety goggles.
