Question about 2003 Mercury Grand Marquis

1 Answer

Wiper blades act on their own

I have a 2003 Mercury Grand Marquis and the wipers work while actually in the OFF position. They come on completely on their own and then when I actually do turn them on for use, the delay does not work properly. This scenario will act out for maybe 2 days and then the wipers act normal again. Does this sound like I need to replace the motor or check the wiring? And how much should this cost at the dealership since I am not handy with cars?

It is possible the wiper module is shorting out. Im not certian of the price but someone that knows how to do it can do it in about an hour.

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.

1997 mercury grand marquis wipers


We have the same problem on our 97 Grand Marquis. We have replaced the wiper blades and the drivers wiper arm with a used one. The problem was not completely solved but it did work better. We are going to replace the arm with a new one and see if that works better.

Wipers will not shut off


It is most likely going to be the wiper motor, the printed circuit board that is commonly made in with the wiper motor may be faulty there are cams inside the wiper motor that tells the circuit when the wipers are in the down position.

How do you remove windshield wipers on a 1997 mercury grand marquis?


If your'e just removing the wiper blade, check for a "release lever" where the wiper attaches to the arm, push (or pull) the lever and pull down on the blade at the same time. Do the opposite to install, except you do not have to push the release lever.
If you are removing the whole arm, there is a special tool that you slide under the arm that releases it from the 'gear'.

Wiper speed control for a '97 Mercury Grand Marquis. What causes the wiper to work on high speed only?


Intermittent wiper control stopped working on my 1996 GM last spring. I ended up replacing the wiper motor ($100.00 part). Since I have found it on Amazon for $58 including shipping. It works fine now. Only bad part was all the "stuff" that has to come out (like dead leaves!) to get to the wiper motor. Also make sure you have your wipers in the down position when you replace the motor.
