recently my durango has been making noises when i lock or unlock the doors, i think the little motor that powers the locks is starting to fail. not only that, but the driver side window doesnt open anymore. anyone know where i could get the motors for the doors?

I don't know anything about the locks, except I'll bet it's likely a solenoid, not a motor.

I do know that I had to buy the window motors (I replaced 3 of them at various times) from the dealer.
And by the way, could not buy only the motor, had to buy the entire raise/lower mechanism...about $130 each if I remember. It's a continuous loop cable mechanism, not the scissors-type you usually see in American cars. There's a ridiculously weak, design-flawed, plastic piece that the cable slides through. It breaks easily.

Might be available through some aftermarket on-line place now, though. I don't know.
Good luck.
