I have a 2004 Lincoln Town Car where the high speed windshield wiper stopped while making a whining noise on the other speeds. Now all speeds have stopped. Will a new motor cure the problem or is there a electrical module that controls the motor?

Have a qualified repair shop check it out . Electronic module involved , WCM - wiper control module . May have code's stored . You have no clue as to how it works.

The windshield wipers are controlled by the wiper control module and the driver-operated multi-function switch on the steering column, with the ignition switch in RUN or ACC position.
There are four modes of wiper operation: OFF position, the wipers move to and stay in the park position; Interval position, the wiper control module causes the wipers to cycle, separated by pauses, pause time length being determined by switch location; LO position, the wipers will operate at low speed continuously; HI position, the wipers will operate at high speed continuously.
The windshield washers are controlled by pressing inward on the wiper switch end of the multi-function switch. The washers will operate as long as the switch is depressed. If the wipers are in the OFF or Interval operating mode, the wipers will begin in LO speed and the washer pump will pump fluid from the reservoir to the nozzles. When the switch is released, the wipers will complete three cycles and then return to their previous setting. In LO or HI mode, no change in wiper operation will occur during washer operation.
The washer fluid level sensor is in the windshield washer reservoir (17618) and is monitored by the hybrid electronic instrument cluster (HEC) and displays a WASHER message when the fluid level is low. The washer fluid level sensor and windshield washer reservoir are replaced as an assembly.

You screwed up the wiper motor turning it on while blades were frozen. Replace the wiper motor park plate, or get a reman wiper motor

Sounds like either the speed control for the motor is bad or the entire motor needs replacing.

There might be a black box involved in the wiper control and perhaps a relay but without a circuit diagram it would be difficult to point a finger at a possible culprit or decide where to begin checking.

Considering your comment about the noisy motor, if it is accessible it would be fairly simple to check if it has a supply and a ground path and even to check the motor and that would be a good place to begin.

sounds like you need a new wiper motor and control unit that comes with it

It sounds like your wiper motor is dying

This controller or wiper governor as ford calls it is located behind the glove box.

Hi this is a common problem for these cars the whine noise is coming from the fuel pump and once they fuel pump starts whining the life of that pump is very short the best thing to do is replace the fuel pump and your fuel filter it shouldnt cost much mainly under $100.

Is the noise coming from wiper area when you are driving on the highway? If it is the most likley solution is to replace the plastic peice at the bottom of the windshield that goes all the way across, on the outside between windshield and hood. when the wind hits it it makes noise.
