Quick question about this. I'm about to do the procedure in the morning and want to know if it's necessary to disconnect the battery. I've looked at several guides and youtube vids, and no one seems to do so. If not, should I remove the fuse, and does anyone know the number of the fuse that's in circuit with the front wiper motor? Thanks!

Thanks for the advice, and thanks for a really useful guide. I didn't bother diconnecting the battery in the end since you will actually need to periodically test the motor and then check alignment and direction of travel etc, as outlined below.

I recommend anyone to try this, requires very little experience and few tools other that 10mm, 13mm sockets, ratchet, phillips, etc. If you're very careful and take your time you won't break the scuttle panel, windscreen or anything (although I came close). The hardest part for me was dismantling my linkage arms and swapping out the motor. You need to pry it all apart with a fair bit of force. Be careful and use a big, heavy screwdriver. Sustained force was the most effective way of doing it rather than vicious jabs(!). I had to do it all twice because the first time I installed it the wipers were going clockwise instead of anti-clockwise! Some head-scratching and a second removal, dis-assembly and re-assembly sorted it out. Basically, before reassembling the mechanism again first take just the motor and reconnect it to the loom. Put your key in the ignition and turn the wipers on. Allow them to do a full cycle and come to a rest. This resets the position of the motor to park the wipers at rest. Now disconnect the motor and reassemble the linkage and bracket. What you do here is very important: line up the two linkage arms as well as the motor spindle arm so that they are all in one line, parallel to the bracket. Crucially the motor spindle arm needs to be pointing in the direction AWAY from the motor, not doubled back over the motor in the opposite direction. I found that this allowed my wipers to sweep in the right direction once fitted. Hope that helps, and thanks again for a very helpful guide :)
