I have an 04 Expy 5.4L 4x4 and the other day when my wife got in to drive she notified me that the Pedals did not adjust any longer. I gave it a try and when you press the switch in either direction you can hear the electric motor trying to move the pedals in the chosen directionn then it stops. it sounds jammed. the motor doesn't stay engaged even with the button still depressed.

Any ideas?

thanks
