2003 Navigator Air Compressor

Hi I saw your other post and I was wondering if you could help me. I ordered a new air compressor but I'm not 100% sure how to change it correctly and I don't want to pay another outragious bill! Do you know how to change it or can you provide resources? It would be even more helpful if you can describe it with detail and maybe a picture? I know this is a lot to ask lol but I'm in great need of help. Thanks so much!!

Since you already bought the compressor it sounds like you did the right thing. I would seriously consider switching your Navigator over to coilover suspension when the next component goes out...probably won't be too long. You can get a kit like this to do it. Cheap, reliable and easy.

2004 Lincoln navigator air suspension all the way down front and back if I was to jump the relay to turn compressor on should the truck start raising up unless compressor not pumping or a leak

no it wont. the air suspension works as a complete system. each air spring has an electric solenoid, each corner has an electric height sensor and then the compressor itself. just energizing the compressor will not open the solenoids or sensors both of which are needed to raise the vehicle. what is probably happening is a failure in the computing system for the suspension system. expensive to repair.

Is there a way to manually fill the air ride system on a 2003 Lincoln Navigator?

yes, locate the solenoid cable in the strut it opens with 12 volts, cut the cable and install a new line and a switch to the battery.
do the same with the compressor to run manually. it has an electrical line to start the compressor and other to open a valve to release the air from the air bags they share the ground cable. thats all.
you switch on the compressor and switch on the desire airbag to fill it. repeat the cycle for each bag.

I just replaced my air compressor on my 2003 Lincoln Navigator. When I turned it on the rear end aired up to the highest it could go and my front never aired up....Help what could be the problem?

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

2001 Navigator rear suspension sagging. While

It sounds like one of your air bags could have blown. I would check them first. I would also suggest checking into a replacement non air conversion kit from Strutmasters. I replaced the air system on my 2002 Navigator and saved a lot of time, money and headaches.The lines on my navigator had holes in them and I replaced the compressor twice before I realized it. Very costly. Avoid all the hassle and check out Strutmasters.

Check suspsension came on in my 2003

Sounds like your air ride suspension is either leaking air in the air bags, air lines,etc, or the compressor is not working. If your truck is still under warranty take it to the dealership to get it fixed or with a good mechanic. If it is an air bag or the compressor start checking online for any good, cheap parts because parts for this SUV run expensive.
