Hi ive got a skoda fabia elegance 2007 new model 1400lt diesel my electric windows not working?

Took it to my local garage he told me the window control unit had gone so looking for a new one at a good price or good second hand one.|||This Happened to my 2003 fabia 1.2 htp at 3yrs old. The dealer fitted me a new one %26amp; advised me to change the other control unit as well. I did not do that and 6 months later it too failed. so instead of one bill to pay i ended up paying twice. also any repair done by the dealer is guaranteed for twelve months and if it fails should be repaired free. I had it done and it never gave me any further problems. I now have a new fabia and the car is wonderful.
