This is a Problem with the Switch Housing inside the Steering Column. You will need to Pull the Steering wheel and a Few other Components to get to this. Usually better left to Pro to Repair as it is Pretty Labor Intensive.

Windshield wipers do not shut off on my mercury grand marquis 2006

Could be the wiper stalk. Also could be the wiper motor derailer. The derailer shifts the internals of the motor to a last cycle so the wiper finishes the stroke cycle and parks the blades.

The problem is you need a signal from the wiper stalk to make the derailer work. You would need to read a wiring diagram and find out if the signal to the derailer is reaching the connector for the wiper motor. If the signal is coming from the wiper stalk, then the wiper motor is not responding when it gets the signal. Then the wiper motor is bad.

Why do my windshield wipers only work on high speed and when turning them off they stop where ever they happen to be, not going all the way down?

could be the motor wiper or the wiper control module first unplug electrical conector at the wiper motor, clean both the elect. connector and the motor connections as well, if this dont fix the problem you will have to change your wiper control module.

1996 Mercury Grand Marquis wipers don't work. I changed the motor and the fuse isn't blown

You need to take the plastic cowls off that cover the wiper arm linkage and wiper transmission to inspect it...cowl is held on with 3 Phillips screws near windshield and some one inch wide metal clips, take off the gasket that fits on top. If both are not working check the transmission where linkages attach, if one wiper blade is not working it is usually the drivers side where the nylon bushing that forns a ball/socket sort of connection fails due to build up of debris and the rusting of parts that follows, let me know if this helps.

You have a bad park in your wiper motor, just replace the wiper motor and it will fix your problem. I work for Yellow Cab of Kansas City and we have 240 crown vic's on our fleet. They are the same car pretty much and we have this problem all the time. Good Luck to ya!

My 1993 Mercury Grand Marquis windsheild wipers works well,but when they park its in the up position toward the roof of the car.What is the problem. THanks Joe

There are contacts inside the wiper motor. The electric signal from the steering column is going through to a part inside the wiper motor which is suppose to derail the electric contacts and shut off the wiper. Part of the system is working if the wipers shut off, but the other part which makes the cam inside complete the shut off cycle is not working.

You can check with an autoparts place to see if those small parts are available. Sometimes there are parts in a "Help" rack section that have odd parts like clips or fasteners which may fall off or break and keep a larger part from working (like your wipers). You would still need to get inside the wiper motor to change it.

Wiper motors are available in the Aftermarket or you can save money by using a Salvage yard. Your used wiper was working for many years until it finally broke. I hope my solution is very helpful to you in fixing your vehicle.

1996 Mercury Grand Marquis - wipers will not work. Have check multifunctional switch and motor. Both ok.

if motor and switch are ok and the motor is running, then it's the ball joints on the arms that have become disconnected underneath the windshield in the firewall vicinity. Also, the wiper arms could be stripped out.
