2005 avalanche memory seat problem

Tonight when closing my vehicle up for the night, I accidentally hit the exit position button, The seat went all the way back and semi reclined. Problem is when I hit my memory 1 or 2 button, the seat will not return forward so I can reach the pedals! When I manually try to slide the seat forward, I only get slight forward movement , then it stops. Help! I need to drive to the doctors in the morning and can't reach the pedals to drive! How do I clear the memory or solve this problem??
