Seized Wiper Motors
OK this is a simple guide on how to fix a seized wiper motor. It's just how to fix ones that no longer turn at all and not ones that don't return or have lost a speed (usually the fastest one) but once I have learnt that I'll update this page.
Now here is the problem:

As you see in this photo when I took the cover off the motor the bearing that holds the shaft in place came with it (meaning the bearing no longer turns freely on the shaft, causing it to not work at all).

Another showing were the other bearing was pulled out with the shaft:

Now to take the seized bearings off the shaft so they can be re-lubed up and put back into the housing.

Removing the bearing from the shaft of the gear that turns the wiper arms. These come out by pulling them out. A good way to find out if a wiper motor works is to grab the end that the wiper arms attach to, and, by pushing it in and out, if it moves then its not seized ! but if there's an electrical problem then only one way to find out and that's to plug her in and test it.

Grease all the bearings and shafts up so they can turn freely.

Place the gear back in once I replaced the newly greased up bearing and well lubricated the shaft.

Now the slightly tricky bit. To place the motor shaft back, you must hold both the brushes in (spring loaded). The way I did that was to place them in and hold them with my left hand while I put the base of the shaft into its bearing. Then push down until it comes in contact with the bush, once there lever out all the brushes with a flat bladed screwdriver so the shaft can be inserted all the way.

Now it's in you can put the two covers back on it and test it out :D
remember to put the wiper arms in the right spot or you'll find that it will try and rotate the wipers past thier normal travel and stuff your paint :D
hope this short guide helps someone, will update it as I learn more.
