Yeah the rear door handle is worth buying from the stealer, look up the part then put in the part number in mitsubishiparts.net to make sure your dealer of choice is giving you a good deal. Like Monte3 said i think i paid 50 for mine and you get the whole assembly minus the cover. The seat might just have dirty contacts in the switches. Move the switches back and forth a bunch and see if it moves and if it does take it apart and clean it with electrical cleaner and steel wool.
