My driver side seated adjustment has not worked so I just took out the cylindrical mechanism that looks like your it is hydraulic action. However, my seat but not adjust so I took out the mechanism and I found out that spinning it somehow makes the rod go up and down. Now as I've gotten it to a point it will not spend any further up or down. How do I fix this I just want to be able to either one put it back in at its lowest point and just leave it fixed. Or two completely fix it and use it as it was attended. I'd greatly appreciate an answer thank you
