I have a 2004 Lincoln Town Car. The windshield wipers began acting up. First the high speed stopped working. Now all continuous speeds and intemittent have stopped. Does it sound like a motor replacement will solve the problem or is there an electrical module that controls the motor. The motor has been making a whining noise.

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.

SOURCE: speed control switch replacement

Depends, steering wheel buttons, on throttle body?
If it is on the steering wheel I suggest you purchase or consult the repair manual. There are a lot of steps you have to take.
Most importantly if this is it. Make sure you follow correctly the procedures involing the air bag.
You do not want this to go off.

SOURCE: Lincoln town car 2000 - whine in the rear

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.

SOURCE: Where is the windshield wiper speed control

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

SOURCE: Windshield wipers get slow and then quit.

It sounds like your wiper motor is dying

SOURCE: fuse for windshield wiper motor

It may be the windshield wiper module instead of being the motor, since you have had that replaced 3x already. There should be no fuse issue.

2001 Lincoln Town car ...wipers at times are slow on high and regular speeds and even stop working altogether.Have new battery 12/17 and wiper mot3/18. Battery is 650cca and on third motor in 1.5 years....

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.
