Thanks, I contacted trutlands and they said they get 151.00 for the part. She said they may do a little bit less. I will give that a try. Thanks for the help

Correct, the seat with the bad sensor will not move with the activation of the top switch. I had the driver's side sensor go bad on my previous spider, and while it was broken, the passenger seat would not move far enough forward!

With that in mind, if the passenger seat is the one not moving, I assume that one should be looked at first? The drivers seat goes too far forward, but is that because the rest of the sensors are not activating?

Taking the seat bottom apart is not brain surgery. You just have to take your time to avoid any damage to the seat and the door sill. Also, access to the bolts that hold the rails to the seats are only accessible by sliding the seat back and forth. This requires you to remove the seat, remove 2 accessible bolts, plug the seat back in, slide the seat the opposite direction, remove the seat, and remove the remaining 2 bolts. Fun!
Removing the sensor from the seat rail assembly requires drilling of rivets that hold the assembly together. I replaced them with nuts/bolts. The sensor is driven by the power seat motor via a shaft that also is responsible for sliding the seat forward and back. From what I can gather, it simply checks which direction the seat is moving, and completes the circuit for the ECU. I have heard of one electronic engineer that took one apart and repaired it instead of replacing it. If you're an E/E go for it.
Incidentally, if you unplug the sensor the top will go down, but the seat won't move. You can also lower the top via the overide buttons located in the center console behind the driver's seat right seat bolster. Just be sure to move the seats forward first!

The problem happened about 2 years ago then went away. Now it is happening again. Could it be loose? If it is part of the seat rail assembly, is it a servicable part that most home mechanics could fix?

Brian has hit the nail right on the head concerning the potentiometer. FNA will only sell the sensor as part of the seat rail/power seat motor assembly. Big $$$$. The sensor is available seperately from European sources. It does require a fair amount of disassembly to replace however. (It seems they built the whole seat bottom assembly around this sensor.) Pay $850-1000 for the seat assembly or $96 for the sensor (from T.Rutlands). The choice is yours.
Good luck!

The problem is usually the potentiometer fitted to the seat rail, check to see if it has come disconnected by something pushed under the seat,otherwise it will need replacement.

I have tried several different scenarios like that without any luck. When I put both seats forward manually the top still does not operate. The drivers seat seems to go too far forward as well(pins me against the steering wheel)when I use the top switch.

what happens if you put the passenger's seat forward on your own prior to engaging the console switch?

My top is having trouble going down using the top switch on the console. The problem is that the drivers seat moves forward but the passenger seat does not and the top does not go down. I can get it to go down using the emergency switch behind the seat. Has anyone else experienced this problem? If so what was the cause and the cure? Thanks in advance.
