1980 Honda Accord 's power steering issue.

I have a 1980's Honda accord. My car had been parked in a humid garage, due to which it's entire rubber seals had been damaged. Therefore, I had to change those rubber seals, however, unfortunately, it's power steering is malfunctioning. My car's power steering turns towards the right side automatically without any man handling, whereas the left side tightens up and doesn't work at all. Also, the car's oil pumps had been replaced but one side has the same problem as the power steering. Please help me find a solution to this problem, so I can bring my car back to it's original position.
