Well, it sounds electrical (Switch, or something) if it will only go in one direction, regardless of position.
With the '03 you can do the code-check (Hit F1 and F6 together on the radio for 5 seconds) and see if you get any errors from the MSM module...

ircuit Description The sensor that set this diagnostic trouble code (DTC) is attached to the seat directional motor it monitors. It receives a 5-volt reference and low reference from the memory seat module (MSM). The sensor sends a voltage signal that varies with the movement of the seat through the sensor signal circuit to the MSM. Then based on this voltage signal, the MSM determines the position of the seat. Conditions for Running the DTC The MSM must be powered and cannot have B1327 - Battery Voltage Low set as a current DTC for this DTC to set. This test will run only when the motors are active. Conditions for Setting the DTC If the sensor signal received by the MSM from a motor being driven in a commanded direction changes by more than 10 counts or 0.2 volts in the wrong direction, the MSM will set this DTC. Action Taken When the DTC Sets Current and History codes are set. The MSM disables the affected motor during memory recall operations. The affected motor will respond to manual positioning commands. Conditions for Clearing the DTC The MSM will clear the DTC as an active DTC, whenever a manual switch is activated and the MSM senses that the voltage from the sensor signal changes by more than 2 counts or 0.04 volts in the correct direction. Diagnostic Aids All position sensors use common 5-volt reference and low reference circuits. Test Description The numbers below refer to the step numbers on the diagnostic table. This step checks the direction in which the volts change as the switch is activated. The voltage should increase for the forward or up position and decrease for the rearward or down position. This step checks the polarity of the seat position sensor wiring. This step checks the polarity of the seat motor wiring. This step checks the polarity of the seat switch wiring. Step Action Yes...
