Well as far as the price of the part goes, I am not sure but I think they are a little pricey. It might be 75 bucks but it might be 175, I don't recall.
They don't let me have anything to do with money at work!
After you remove the hush panel, you can look up in there, back towards the radio/hvac control up high you'll see the actuator.
The new one comes with a big plate on it and a cam looking device, DON'T REMOVE that from the car!!
The trick is to only take out the 2 5.5mm head screws that hold the actuator to the cam plate. Then pry them apart.
Do the same to the one in the car. Then line up the new actuator to the old cam plate and put the screws back in. If you remove the actuator with the plate you'll never get the doors timed properly.
Technically the service procedure calls for the removal of the dash to access the actuator.
Remember there are two actuators up there, you want to replace the one closer to the driver. The other one is easy to get off if you want to take it out of the way but don't mix them up.
It's still no fun to do.
I did one the hard way a few weeks ago, and I had to do it twice because I mistimed the doors on reassembly. I hope you never experience that.
