Octavia 1z (basically for this any octavia new 04-old 2013) front wipers not working

Hi all I have front wiper issues with My 08 octavia scout inital 1st thing  I noticed was the last few weeks before the wipers came to a halt they were often a little slow and parking funny til suddenly had to hand assist the wipers to park and within a day or 2 wipers stopped working!..As suspected it was the wiper regulator seized up now obviously solid common issue I have seen many times before with various vags over the yrs and more often than not with success managed to strip down the linkage clean up and lubricate and reassemble and job done ANYWAY with how seized mine was ended up being undoable and job wrecked!.....So ordered a used motor/regulator assembly off ebay fitted all back together (yes I know about the bonnet switch) and not working (although now thinking maybe fuse before going down the get the book  out blah blah blah) opted to rig up the old motor alone and still not working so from there checked the fuse (found to be F19 or F31 depending on exact fuse box if thats correct) and still no better off fuse fine infact cheacked all the underbonnet fuses and all fine so now pretty much stuck? anyone else had experience with this issue and what have you found? any useful help much appreciated Ta
