Hi, I was wondering why one of my features on my seat doesnt work, for example. I can't move my seat back and forth, however, I can move it up and down and tilt the top part back and forth but the bottom part of my seat I can not move back or forth. Makes it harder for my brother to drive my car cuz hes 5" taller than me please help. Thanks. Its only on the driver side btw. thanks.
