The power lock mechanism on these have this plastic gear setup and they crack. When it splits it just spins and makes that noise. You'll have replace the module, about $60 IIRC.

Idk if you already checked this but when I have a similar problem one of my spark plugs has gone bad.

That's a good (and cheaper) place to start. You might also check belts (water pump at least) for cracking and glazing; the circulation rate doesn't have a lot of latitude and a slipping belt can have an influence.
Also, is your electric fan running when it should?
Also, once you are under the hood, check your oil for any signs of Jergens lotion (water/coolant contamination) and your overflow bottle for any signs of oil floating in it.  If you are going to get your hands dirty anyhow, you might pull your plugs and look for any suspicious rusty discoloration. This paragraph is assuming bad stuff; namely a failing head gasket which can also cause overheating if it has failed between a cylinder and the water jacket; during combustion, hot gases are pumped into the coolant which also should cause bubbles that you can see in the overflow bottle.  

Hi Summit, Take the vehicle for a diagnostic scan. The gearchange is controlled by speed sensor signals which also serve the ABS system and traction control. It could be something simple like one sensor having dirt contamination or defective signal output. The scan should pin point the problem. Regards John
