Hi and thanks for reading ive recently bought a 2009 vw golf gt tdi 140 on returning home with the car i found that the rear doors and rear windows aint locking or coming down ive checked all fuses there fine the computer is saying no connection to both rear doors there no sign of broken wires also under drivers seat there is a compartment in the floor ive noticed that there a big block connector there but it dont go into anything is there a module missing and also if it is does it control rear doors and windows
