Question about 2000 Mercury Grand Marquis

1 Answer

Auto maintanence On my 2000 Mercury Grand Marquis, the driver side wiper does not always completely clean the windshield during heavy rains. either the "up" stoke or the "down" stroke may leave rain on the windshield. I have replaced the wiper blade & even exchanged the wiper blades from passenger-to-driver side with the same result. Is the wiper arm itself weak on the driver's side? How do you replace that wiper arm? Are there diagrams I can access on-line? Thanks for your help! Pianotech

Someone will probably need to remove the wiper arms and the panel between the hood and the windshield to access the linkage coming from the wiper motor.

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.

2000 grand marquis driver's side windshield wiper lifts off windshield

Hello Steve,

From your post, "Finally had enough and stuffed a small block of wood between the driver's side bottom of the molded plastic linkage frame enough to lift the whole thing enough to put a moderate amount of pressure behind the wiper blade..", it sounds like this box is warped or somehow out of alignment. Is it possible for you to buy this box from a wrecking yard? Has you car ever been in a collision? If so the frame may have so un-repaired buckling resulting in the misalignment.

Heater core is leaking on the floor

I had the same problem with my 2001 Mercury Marquis, but it wasn't the heater core, it was the compartment for the condensate drain for the air conditioning and the compartment to catch the rain water that comes down the windshield and drains through the windshield wiper cowling. You have to take off windshield wiper on passenger side and cowling underneath the wiper of the passenger side and you will see a screen over in the corner and that's where the box is for the drain. so much trash was down in there that the flapper wouldn't open to let the water out. Ours only leaked when it rained, but it looked like it could have been the heater core. Good luck.
