Hello everyone, I have a 92 Pontiac Bonneville ssei and the seat adjuster switch is going weird on me.The drivers seat works perfectly but when I push the seat selector to the passenger side seat it is still moving the drivers seat very slow.I have taken the seat adjuster out and have it apart.The seat selector switch operates 2 slide switches at the same time.The 2 slide switches are right above each other on the circuit board.The lower switch seems snug and the upper switch seems loose.My question is have any one else had this problem,I am going to unsolder the upper switch tomorrow and remove it from the board. I think this is the problem but would like someone else'* input on this.I did run power to the passenger seat and it will move.Thank y'all

No sir, Everything else is working fine. I really appreciate you taking the time to send the diagram,I removed the upper slide switch And checked it with my meter. It is not working properly, I can put side pressure against the switch And it will somewhat work.I think you are correct on buying another one, That'* what I am gonna do.I really appreciate your help.👍👍
I was going to say, if you ever have issues with power windows, locks, seats and engine not starting, there is a ground buss behind the drivers side, LHS kick panel that has a tendency to **** itself with corrosion. Yes, the fuel pump ground circuit is tied into it.
