Question about 2003 Lincoln Town Car
I had experienced the same problem with my 93 TC. I'll try to make it short. Replace the Idle Control Valve. Cost me $50 at AutoZone. It has a electronic plunger that has a rubber o ring on the end of it. It separates two air chambers inside the valve. When the rubber gets old and the plunger is suppose to cut off the air coming in from one chamber to the other, the air gets sucked between the chambers across the old rubber causing the humming noise. That is also why the engines revs up and down and wont idle right. It is located between the firewall and the back of the motor just to the left (drivers side) of the throttle control assembly. When you look up on the internet on how to replace it, it will tell you to remove all the housing surrounding the wiper blade control arms and assembly so that you can access it. If you take your time, just remove some of the hoses and wires connected around it and you can access it without removing all that ****. Only has two screws to it that point up and can be reached with a ratchet and extension. Car runs great now and finally got rid of that noise.

it is either a tire or you have a wheel bearing going bad. sounds like a bad bearing. you can usually narrow down side by driving and turning the side that is bad will get louder when weight shifts to that side and quieter when weight shifts off

I had the same problem in my Lincoln Town Car about a year or so ago. Here is what the problem was. There are a couple of air ducts at the back of your hood (top of firewall just below the base of your windshield wipers anchor points) These ducts are located one on the driver and one on the passenger side. Each of them has a little gate at the opening. The gates on my car were clogged with leaves and debris, thus causing water to flow over the ducts into the passenger compartment of the car. These ducts must be cleaned out so the water can flow through them and down to the ground instead of overflowing due to clogging.

Those Lincolns are notorious for that,I'd just get a set of coil springs out of a Crown Victoria cop car(junk yard)and swap them out.Done it many times,you can do it in about an hour,and they'll never leak down again.By the way,there's some O-rings in that system.Make some soapy water and spray every connection,just maybe you'll get lucky.
