Front/driver seat problem

[oyama]

I just bought Buick Lesabre 2003 and need to fix the front seat on the driver side. The issue is the following: I cannot slide the seat back and forth because there is no pull handle. I was trying to sort out how I could move the seat without the pull handle but it's somehow difficult (although I have the pull handle on the passenger side, underneath both seats looks much different). Could anyone advice me (maybe somo photo or drawing) of the properly installed mechanism. I don't know how to trigger this seat to move...
I will be grateful,
Mac

Do you have a power operated seat on the drivers side?
