Ironic!

Just performed the procedure last weekend for the passenger side leak...driver's side cylinder leaked last summer.

There are a total of six screws to remove in order to get the cover off. The 2 big screws holding the plastic hinge bezels at the top, a screw on top of the rubber in the front corner of the driver and passenger window, and if you pull the innermost part of the rubber away from the body, you will see yet another screw with a trim washer that has to be removed (each side of course).

The whole deal attaches via clips along the front of the windshield, so removal requires lifting up from the rear, then pulling out. A bit stubborn to do the first time. There is a sensor attached to the panel, so don't yank it completely off!

You will need an allen wrench, a small crescent wrench and a torx head screwdriver to do this job properly. You can do this without the torx (used to remove the three bolts that hold the entire hinge mechanism in place), but the small confines make the removal of the cylinder pretty tedious.

BTW, the system is self-bleeding, so once installed, you don't have to do anything else...except maybe check the level in the fluid reservoir, in case you've leaked a lot...
