mk2 drivers window stuck

right wonder if anyone can help,

my 06 mk 2 octavia drivers side window got stuck halfway the other day, although all other windows work via the drivers window controls

, so removed doorcard ect and investigated,checked for power to the motor with multimeter, all is well there,visually checked for chaffed/broken wires, everthing looks intact, couple minor chaffs so tapped them up, nect checked the wires in rubber boot in door jam, same there couple of minor chaffs, taped up, still drivers window wont function, all other windows fine, next i swapped the complete switch unit from my octavia with my partners mk5 golf, all buttons function with my switches with the golf,

so now im stuck, so i buy a second hand motor and module, expecting that to solve the trouble, no go, the part i bought has same part number and only last letter is a J, and my cars original ends with a H, the unit i bought doesnt even seem to be seen at all by the car, the window lock swith light does not illuminate at all or anything funtion when connected, would it need to be coded because the last letter of part number different?? i would have thought the letter would just mean a newer revision and work merely just connecting it ,

anyone got any ideas how i can proceed to fix my problem
