power lock actuator
 

Is there a better alternative then buying a new one from ford for $50 each? How hard is the install? I don't want to buy a used one for the junk yard because I will probably end up with the same problem again.

i think the new ones from ford are updated.
try ebay.

I went with the el-cheap-o aftermarket actuators. I'm on my 2nd set in a little over a year (1st set succumbed to a bad switch keeping them on, this last set is blowing a 20amp fuse after a few actuations). You get what you pay for.

anybody know the ford part numbers for passenger and drivers actuators side by chance?

nope, bob might.
just call ford, they will hook you up with everything you need.
