    Default 355 power seat issue

    Hi

    Ok so my up until recently both my seats have worked fine, my passenger seat still does!, the issue is with my drivers, now last time out I noticed it wasnít behaving properly, it wouldnít move as far forward as it should, was a good few inches further back than the passenger seat would reach, after a few backwards and forwards requests it went the same distance forward as the passenger seat.

    Now however the drivers seat will not move at all, ive had a little nosey underneath best I can and everything looks like it is connected, except thereís a clear plug Which is disconnected under both seats which I assume is those seat sensors for the roof!

    I have some questions

    1) in between the seats there is that panel, which once removed has 2 fuses and 2 relays, I think one set is for the roof and the other the seats, is this the case that both seats share the same relay and fuse?

    2) is there a way to manually move the seat? As it is now I donít see how I can remove the seat as I cannot move it to access the bolts ( I will attempt to rig a set of leads to the drivers motor to see if the motors ok, but would like a plan B if this isnít the issue)

    I assume it's a Spider, it will be a failed potentiometer under the seat, it's a common problem, basically it disintegrates and the seat stops moving. IIRC if you take the small cover off the side of the centre console (passenger side) there's a switch/ method to make the seats move/ roof go down so you can access and replace the failed unit. Note you'll need somebody with a Ferrari SD1 diag tool to reset the forward and return positions

    Yes a spider

    Are they not the clear/white plugs, both my seats have a clear/white plug disconnected.

    I assumed my car had bypassed these sensors as I have to move the seats using the switches before I press the roof down switch

    Ah probably yes, so the potentiometers need replacing and it sounds like the motor may have failed as well

    Iím hoping not as itís going to be a struggle removing the seat if I canít get access to the bolts!

    Do you know if both seats share the same relay and fuse?

    Sorry Jame I don't know the answer to that, might be worth taking a look on Ferrarichat or asking the question there, typically they tend to be a bit more DIY than we are over here
