Sorry to tell you this, but this is the worst design ever. It is the "regulator" the motor drives a flexible shaft that raises and lowers the window. There are repair kits available on ebay. But it depends on how yours is broken. If the plastic shaft has separated from the motor housing, I think you are sunk. I've seen them on ebay. OEM down here(PR)was close to 300 as I recall. Be very careful installing the new one, the shop here bent it too tight and broke the new one. He bought the second one.
