From the Service Manual:
Battery positive voltage is supplied at all times to the seat adjuster switch from the TELE SWITCH/MSM fuse located in the body control module (BCM) fuse block. When a seat adjustment switch is pressed, battery voltage is applied through the switch contacts and the appropriate switch signal circuit to the memory seat module (MSM). The MSM then commands the driver seat motors to move in response to the switch signals.
However, the seat schematics show a 30 amp circuit breaker located in the I/P electrical center Vs a fuse. The breaker feeds power to the Memory Seat Module and may be the power source for the motors Vs the 10 Amp fuse that may only power the Seat Module electronics. Have you checked the circuit breaker? It is on the far right side of the panel second breaker from the top.
If the circuit breaker is OK then get the codes read and see if there are any seat codes. A flunky OBDII scanner will not be able to read the seat codes. A Tech2 or something similar will be required. If the Tech2 has communications with the seat module there are a number of diagnostics that can be run without removing the seat.
