If you would like to be considered for this job, please provide two estimates. The first is to tune my stuck sliders by using the adjustment screws only. If that fails to solve the problem, then quote costs for parts & labor to install as needed.

The doors barely slide at all. Their lock is stuck too, of course. One of the sliders is so far out of alignment that it is almost touching the side of the track:
