seat won't go back.

Asked by for the 1999 Audi A6 Quattro
Will it slide forward? Perhaps something is jammed in the seat runner but more likely the motor has failed or the wiring or switch has failed.Perhaps an auto upholstery shop or independent auto repair shop can help.
thank you for your help. Turns out the connector to the seat motor had a short wire and it came loose. Found it dangling under the seat reattached it and thankfully back to normal.
