It is stuck engaged or disengaged? It may just be the hydraulic actuation that is not working. It could even be just low on hydraulic (brake) fluid. Be sure it has brake fluid in the rear portion, which is difficult to see into because that is where the clutch master cylinder gets its fluid.

Good luck
