How helpful! and you wonder why all we're getting cheesed off with your immature attitude on this forum. Ever heard of the saying 'if you've got nothing useful to say, say nothing' ?
The slow wiper problem is very common on the mk4 Golf and derivatives, and it is most likely to be a mechanical problem rather than anything to do with the wiper motor or electrical supply. The usual problem is that the driver's side wiper spindle seizes up due to water getting into the greased housing that supports it.
Luckily it is actually very easy to fix, you will however need to remove the complete wiper motor assembly from behind the plastic scuttle panel at the bottom of the windscreen (see Foxy's cruise control installation guide for some instructions for this procedure - http://homepage.ntlworld.com/dgace/wiring_-_outside.htm)
Once the motor assembly is out, you need to remove a small circlip from the wiper end of the spindle shaft to release it so that you can drop it out of the aluminium housing. CAREFUL at this stage that you don't 'ping' the circlip off (hey Richard, remember that one at the cruise fitting session!!).
Once you've got the shaft out (which may require some force if it is badly rusted!), carefully separate the small o-ring(s) and washer(s) that will be fitted at each end of the shaft and clean them up ready for refitting later. Polish the outside of the shaft to remove any rust - use some fine (400 grit or more) wet'n'dry / silicon carbide paper until you get rid back to a smooth surface. Refit the spindle and washer and o-ring after lubricating liberally with a water resistant grease (I've used a PTFE bike grease before) then refit the circlip and reconnect the operating link to the ball joint on the spindle arm -if that looks a bit dry then put some more grease into the cup before you push it together.
Unfortunately I've seen pretty much the same problem on every Golf/Bora that I've worked on so it's a bit of a timebomb waiting to happen. You'll probably find that the wipers are much smoother as well as quicker afer regreasing, but if you leave it it could seize up completely and then burn out the motor which will be more expensive to put right.
Here's one of the many previous threads on this subject:
Good luck with getting it fixed.
