New member here. Got my polo the other day

The window regulator was broken and wouldnt even go down. Managed to cut it out and get it out, put a new one from euro car parts in, just clicked and the motor sounded like it was trying to move up and down (changed sounds depending on which way you pressed it) but wouldnt actuate the cables on the regulator! took it back, got another one, same thing. Third time it happened again. Had a paddy at ECP, ordered another one from ebay that was all guaranteed etc etc. waiting for that to come on wednesday or thursday so I've got tape holding my window up till then haha!
So basically any ideas why these wouldnt work? I know ECP isnt best however three in a row? fishy, wiring looks alright, havent checked in the rubber conduits between door and body yet however the fact it sounds like it's trying to work is strange. It's a 1.4 16v 75bhp with comfort settings and the most hideous cream interior you will ever see!
Thanks for the help guys
