Replace the AC compressor relay, it may be sticking on. Check the owners manual for location in the under hood fuse and relay center.

It's called the back fender.

Long list of choices, thermostat, low on coolant, water pump, cooling fan, exhaust restriction, and so on.

I would try crawling under vehicle and hooking red jumper cable to big copper stud on starter where the battery cable hooks up, hook the black cable to the frame and hook the other ends up to another vehicle like you were jumping it off. And it should feed the battery with enough power to get the doors open to get the hood up. Good Luck

Is the warning light on ? Has anyone checked for codes ?First guess would be the pump or the height sensor.

You must replace the key pad as a unit, the tiny light bulb is not replaceable. This involves removing the drivers door panel (about a 2 hour job at home)and the rear door glass run channel. I suggest if you can afford it you have a professional do this rather involved job. If you do want to attempt it let me know.

Are you check fuses? Also test wire connections from/at power windows motor and windows switch.

First, you should have a warning light telling you it is not working. There is a switch for the air suspension underneath the glovebox-right hand side or in the rear hatch area on the left panel..make sure it's on. If all 4 air bags are deflated it could mean the air pump or actuator is malfunctioning.

Sounds like either a faulty solenoid or starter. Do you have a check engine light by any chance?

Hi Russel, This is just a suggestion. Is the preset maybe on ballence instead of volume? Regards john

cold weather causes metals to shrink and plastic and rubber parts become hard brittle more likely you have leaking air line or o ring to air spring causing all the air leak out of air spring.

AIR COIL SPRINGS WILL DEFLATE AND BE DAMAGED IF YOU DID NOT TURN OFF AIR SUSPENSION SYSTEM BEFORE RAISING VECHICLE AND CHANGE TIRES IF YOU DONT TURN OFF AIR SUSPENSION IT WILL CAUSE AIR SPRINGS TO OVER INFLATE CAUSE AIR SPRING SPRING DAMAGE.

I only have 2003 Nav procedure. Maybe get used part at car-part.com. Page with * is lowest price.

You most likely have figured out the inner door panel
has to come off

Any work inside a door panel, sorry to say, is a self
taught type of work.

You use the internet to find those type questions
Ask people who own the same vehicle & work on them

Any vehicle you can not see the spark plugs or no wires
going to them, has coil-on-plug ignition

They are under the coils on all ford v6 & v8 for over 10 years

Hello, first how many miles do you have on this Lincoln? On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark coil located on a long rubber plug. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on eac coil. There Hello, first how many miles do you have on this Lincoln? If you have over 120 thousand miles on this engine then it might need new spark plugs. On that 4.6 L V8 engine they do have spark plugs but each plug has it's own spark plug coil. You will see four little coils on each side of the engine. There will wires going in to the individual coils. There will be a bracket the holds the coils in place with a small 9 or 10 mm nut. Remove the nut, and gently pull on each coil. There a long rubber plug that fit in each spark hole. These rubber plugs are about 4 1/2 to 5 inches long.


Before removing the plug use an air hose with 50 to 60 lbs of pressure to blow each spark plug hole out which might have foreign object in the hole. Why, if you remove the spark plugs, and there is foreign material in that plug hole. Guess what, that stuff will fall into the combustion camber.



Then you will really have some problem. How fix if stuff fall into the combustion camber.

Squirt small amount of oil in the combustion camber, unplug all the coils and clear out there plug hole. Now remove all the spark plugs. Now, you can crank the engine and will the little amount in that cylinder that has the junk in it. The oil will wet the foreign debrie, and blow it out the spark plug hole. Then use a clean rag with with some oil it with a long screw driver to clean that spark plug hole Be careful that don't push the foreign material back into the combustion camber. Do this several time with little amount of oil.



Now, you can install the new spark plugs. On the spark plugs threads use some anti-shiz grease. Why squirt oil into the combustion camber? The oil is used to seal the rings on the piston to increase the cylinder compression. Just a small amount goes a long ways. GB...stewbison

Hello nicholasrico,

This engine is a coil on plug arrangement, first you need to remove the coil cover, two bolts. See image below.



To access the plugs you must take each coil off, the plug is directly under the coil. See images below.





Repeat this procedure on both sides.

I hope this helps.

Regards,

Jerry

Clicking could be from any part of your suspensions. Have a mechanic look at it as a manual diagnosis of the car in person will be necessary

You can get the owners manual with the fuse diagram on the link below.
