2003 lincoln navigator compressor does not want to turn on

Had this issue as well. Problem was with airbags and compressor. Ended up replacing air ride suspension with coil springs.

MAY CHECK TO SEE IF LINES ARE PLUGGED WITH DEBRIE OR SUGGEST DISCONNECTING THE AIR LINES WITH VEHICLE OFF START VEHICLE MAKE SURE AIR FLOW IS COMMING OUT BOTH LINES SHUT OFF AUTO RECONNECT LINES THIS SHOULD BLEED THE SYSTEM THEN RESTART AUTO.

Check for battery voltage at compressor clutch. Check ECM
(computer) for A/C command. Problem could be in control panel.

Make sure A/C button is on (if equipped)

leak at rear air ride shocks or bags.

check for a leveler adjuster could be stuck or if you are sure that you have front air shocks the line could be leaking hoses cracked or broke or the shock itself could be damaged to check further to find the problem

Check all your fuses. in the dash if any and in the hood if any. Sounds like the circuit overloaded and shorted out.

My 2003 Lincoln Navigator has given me so much problems, it shakes, makes annoying sound, and sometimes it turns off by itself when I'm in a stop sign or red light! I have taken it to 3 different mechanics who have said that the diagnostic shows that it's not gettting furl? They've tried changing spark plugs, gas filter...any suggestions?

Remove battery, remove windshield washer bottle, remove air compressor and disconnect both air lines from the compressor dryer. Make sure compressor electrical wiring is plugged in, install battery, turn suspension switch to ON, turn ignition switch to the ON position, close all door and the compressor should come on and completely lower the whole truck. Once the truck is completely down, turn the ignition OFF, remove battery and connect both air lines. Install battery ensure electrical wiring is plugged in, turn ignition switch to ON, the compressor should come on and raise the vehicle to the correct ride height.

you need to check your real axle sensor it may have come loose or broken

we had this problem in our shop the other day and there was water in the air lines so we put air line deicer in the lines when the truck was warm in the shop and cycled the suppension twice with a jack. you can find deicer in many truck stops and auto pat stores that sell truck parts
