1996 Chevy Tahoe Interior Door Handle

1996 Chevy Tahoe

1996 Chevy Tahoe - 2 door. The interior door handle on the driver's side will not open the door anymore but the exterior handle works. I believe I've pinpointed the problem but need to see a diagram of the set up to figure out who to fix it. Anyone know where I can find one of those?

Thanks!
