Hi, no, it's not a big job to replace the motor, I have a feeling that your trouble will only be a Connection Problem. "if " it turns out to be the motor, before you start the Job purchase approx a Doz plastic door card clips as the do tend to snap on removal of the door card (Panel) Tools needed, Torx screw driver ( Size unknown) Philips screw driver, plenty of patience if you start getting wound up, LEAVE IT and retry later. when the door panel is removed you face a plastic inner cover, raise this up be careful of the compound the use to stick this plastic cover in place, it gets everywhere, before you start the job AGAIN try the electric motor for movement, also put a test light on the connectors from the window switch if there is currant coming down the switch id OK, does the car have a duel window switch? What I mean by that, can the drivers window be opened from the passenger side? if so try the window again, again as said, check ALL your connections before the final ( removing the motor & window Me-ch) you may find that the assembly comes as one complete unit, IF that is the case & money is tight / short which ever way you want to call it, try EBay, 247 car spares, it will explain what details they need, Eg, Year, which side, front or rear, do not go to the agent before you search as you will pay the rip off dealer prices.
