I have around 253k miles on my truck and I'm always trying to keep it from falling into disrepair. That said, my up/down seat motors were not working and didn't want to spend the $1300 on new seat actuators from the dealer. So I did some research and found motors on www.2men1garage.net. For around $350, I received 4 motors (2 for each seat). The removal and install a little intimidating, but after the first motor, it was pretty straight forward. I'm super stoked with how it turned out. I highly recommend going this route if you are in the same predicament.
