Not really mate.... The difficult bit is actually removing the wiper arms from their splines. They tend to sieze on.
Here is a quick run down.
Remove the plastic end caps carefully that sit at the bottom of the wiper arms, there is a small gap that you can get a small flat head screwdriver in, they will pop upwards.
Remove both securing nuts that attach the arms to the spindles.
Give the spindles a quick spray with the WD40 and leave it to work for 10 minutes.
Gently but firmly pull the arm up towards you around the spindle while giving it a wiggle.
Same again for the other side.
There are two big plastic screw caps either side of the bottom corners of the wind screen, remove them.
Remove the foam blocks either corner of the engine bay near the bonnet hinges.
Remove the thick rubber seal engine bay seal that runs along the bottom off the scuttle panel.
Now simply unscrew the retaining screws for the plastic scuttle panel, it comes in two halves and if IIRC you only need to remove the drivers side half
Dont worry about you windscreen washer jets just gently lift the plastic scuttle panel away for now.
IIRC there is only three securing bolts for the entire wiper mechanism and motor.
Remove them and unclip the multiplug (it can be fiddly). Now simply push down , twist and the whole linkage and motor will slip out...
Re- fit a new/ used item in reverse order.
Usually about 30 minutes worth of work
If you are cleaning up the connections.
There is usually a plastic bag cover over the motor assembly and a flat plastic cap that needs to be removed in order to get to the motor's cycle ring... This is what needs cleaning up... it will become self explanatory when you see it...So don't worry, its not that bad
Hope this helps
