BMW Repair: passenger seat, back seat of my car, test light

Question
i was vacuuming the back seat of my car and i moved the passenger sear all the way forward so i could clean the back and now the front seat will not move back. i am not sure if that is  a wiring problem or a motor problem or something. all of the other functions work. the seat still tilts forwards and backwards and moves up and down it just wont go back. please tell me how i can fix this problem passenger  

Answer
I am sure that there is a broken or corroded wire.Check power with a test light at the switch to determine which wire you are looking to repair.Many time the wires will be corroded inside the casing,which means you will have to replace that section of wire.It may take some time to find but not a hard problem to repair,
