every time I open the hatch the motors burn out or not getting power. not sure what the problem is. I typically replace motor and its good to close but this time its not getting power so I found a company called WestCoast autoparts that sells the complete assembly that's been refurbished. my question is, if I take this piece off and bolt it on the new one is that all I need to work the outside lock? also is that one bolt and screw all I need to remove too get that piece off for the transfer ?
