the above is mostly true
the actuator is specific to left or right door and front and back
it is also somtimes specific to a certain run of production- the design or supplier may change in the middle of production
I bought an actuator on ebay for a very small sum of money
that I thought was the correct part- turns out that it was ever so slightly different and would not fit
I opened both actuators and found that there is a small electric motor inside
with a wormgear shaft - both are identical
just swapped them out and replaced the original actuator with the swapped motor and works perfectly
looked like this:
by the way the dealer wanted almost 600 USD for a new latch/actuator
assembly - purchased a used one on ebay for 25 USD!!!
