A b**ch to do? Really, took me about 20mins to do. Like you say take all that off, all you need is the basics.
I bought my pump of ebay for £6.50 including delivery!
You need a 13mm socket, 10mm socket, ratchet and extensions. The wipers are held on by 13mm nuts, get them off, lift the plastics, remembering the little clips in each corner, take the plug off the wiper motor, 3 x 10mm bolts, carefully remove that, take the plugs of the pumps, (I say pumps cause mine isn't a cup) then one 10mm bolt holds it in, pull it toward the OS slightly as they have two little bumps that sit in the inner wing, then lift it out. Replace the pump and away you are
But before you do all that, check the fuse, and when you get the plastics off check you have power to the pump.
