How to change a wiper motor :)
Discussion
Things you'll need..
A new wiper motor
19mm spanner
13mm socket and spanners
10 mm sockets
6mm spanner
whatever sized allen key to get the inner bonnet off
Flat screwdriver
mastic
grease )maybe)
Assumtion, the wipers are in the park position!
Take off inner bonnet
Cut the cable tie holding the washer tube to the overflow tank bracket
Unscrew platic bonnet catch end thingy (technical me like
)
Undo the jubilee clips holding the top and bottom pipes to the overflow tank (for the bottom pipe undo the top clip, this will make sense whan you see it)!
Use bit of old hose to syphon what you can from the overflow tank
Undo the nut (13MM spanner on both ends) holding the tank to the bracket
Take off top pipe
Hold bottom pipe and pull tank straight up
Undo bolts holding tank bracket off and remove bracket
Use 10MM socket to undo wiper motor bracket, the bolts on mine were under a lot of mastic
Use 19MM spanner to undo the brass nut between the wiper gearbox and the wipers
Using the 6mm spanner take off the nuts holding the gearbox plate on, take plate off
With a spanner as a lever lift the end of the rod out of the end of the wiper attatchment (this will be easy once you see it)
Disconnect the electrical plug
Remove wiper motor
As haynes would say, refitting is the reverse of removal
However, if you connect the motor to the electrical system before anything else you can test it works and also ensure it is in the correct park position.
All in all I think probably about and hour and a half.
Of course the new motor is not much better than the old one, I really do think there is another problem somewhere, do people think that there is much point adding earths?

David, I replaced my motor a while ago. Also had to take the cable out and replace the 'pipes' it goes through. Although the replacemnent motor worked fine, we never did get the cable running very freely, so it's still not quite right.
When you had the motor off, could you move the wipers easily by moving the cable by hand?

How did you change the pipes?

With lots of swearing, bleeding and help from Olly!!! You have to take off the flat piece of GRP that sits below the window, which I think was riveted on, and then remove the black box thingy that goes all the way along the bottom of the windscreen. It was a REAL pain, and like I say, we never did get the cable moving freely. When you attach the motor and mount it, it puts a bend in the system which stops the cable moving freely.
The wipers work fine if the screen is wet, but if I use the washers, before the water comes out, the wipers move half way across the screen and often stop.
Olly, can you remember any more useful hints??

Usfeul hints ?
Well, the motor wasn't too bad, and the description below is pretty good.
But as for hints for removing the wires/tubes - DON'T DO IT !!!!!! Pay a dealer/indi to do it ! For all the swearing
& knuckles you take off 
, it's worth paying someone else to do it !
that must be my most un-useful post ever !

Another useful hint; I drained the expansion tank with a syphon hose, then when I removed it, quickly stuck a spare rubber elbow bend on the end of the metal pipe.
Stopped more water loss.
I found that my wiper motor had seized, this was due to the bottom bearing on the motor drying out. There is an end plate at the base of the motor that holds the bearing, this can be removed and re-greased. I had to clean up the motor spindle a little with emery paper, but it seems to be going ok.
No doubt it'll pack up completely on the motorway sometime this winter.
