passenger seat won't go back and forth

[91vettezr1]

hi
took out driver seat (94 zr-1 sport seats.) to put on new seat cover, after putting it back in the car , the passenger side seat doesn't go back and forth. when i use the switch from passenger to driver, just the driver seat moves. the driver even moves when i click the switch to passenger only. other features ,bolsters,air pump etc work ok. i checked all the fuses, read a thread about switching connectors on drivers side, that can't be done since they are colored coded and only go one way. i confirmed that are in the right harnesses. i also switched around relays on the drivers side,checked connection at seat switch.
i was thinking maybe the switch was bad but the seat was fine before i took out driver seat, any help would be appreciated. driving me crazy. now the passenger side is stuck half way .
