Why isn't my power steering working on a 1993 mercury cougar?

First step would be to check if you have enough Power Steering fluid in the system. If it is low then fill it up to the fill line and it would probably be a good idea to check for leaks in the system. If you check the fluid and it is good, then there would be only one other option, and that would be the power steering pump.
