the problem started two months ago and is yet to be solved

So what do I need to do to fix this problem

When I start the car and close the doors i can hear the suspension pump turn on, right behind the passenger headlight. After a few min of running the check air suspension message turns on and the pump turns off. The front is fine but the rear end is low and makes for a bouncy ride. I've read about a leveling relay or switch but can not find location.
Thank you in advance.

My running board on the passenger side is not going up but I can hear the motor trying, is there a way to tighten it up or what should I do.

Just had a new battery installed

My mechanic told me that I need transmition control modul,cost $3000 .my Lincoln is in Europe,no one really know haw to repair this car .... I apreciate any one with advice,thank you

If I try to back up an uphill slope, car goes forward, have to shift back and forth before I finally can backup, dangerous issue

it started as a slight scraping and only once in a while now its really loud. any suggestions what it might be?

but will shake and lose power at rest or light

I have had oil and filter changed because two mechanics told me the oil weight was wrong and I was not getting enough lubrication to the tappits. Nothing changed. I still have this noise. No wqrning or engine lightscome on ar still runs smooth. Could this be from towing my trialer?

My 2oo7 Lincoln gets stuck in park sometimes. Why?

There is 59000 miles on it and the last 2 mornings the truck did not want to turn over. it eventually did, and would start fine in the work parking lot on my way home after sitting for 10 hours. This same issue happened the last 2 weekends, but we were at a football game tailgating with the liftgate open and I assumed that was the reason for the drain. The truck is parked outdoors and it has been getting cooler out, but its difficult to believe that this is the reason for the problem.

Thank you for the help
