for the control unit... https://www.car-part.com/cgi-bin/search.cgi
car-part is not that difficult, really.. chose year, model, the part you are looking for (sometimes need to get creative, or chose something related) chose sort settings and area, click 'search' - it may ask for more info on the next screen, select the appropriate option, search again.. then go thru the listings..
if the exact part you are looking for - in this case, the actuator - is not listed.. use something related, like the control unit, then contact listed yards and ask about the actuator.
