    So I just received my 95 355 spider and the top is not working.

    I read a lot of threads.

    This is my issue:

    Both seats work,

    I unlatch the top
    move manually
    Windows come down a little bit
    Car makes one bip
    Seat don't move automatically
    Top doesn't go down

    Do you guys think it is the potentiometer?

    Is there a way to manually put the top down until I address?


    Thank you

    Go through usual requirements: engine on (preferably), nothing obstructing seats going forward, parking brake on, doors closed.
    Then when you unlatch top and bring back to beep ensure it stays in position and doesn't lurch forward. Then give it a try- if nothing trying pushing or helping the retraction process with maybe 5 lbs pressure.

    Yep done it, even run the hydraulics to close (works) open/close a few time to prime the pump and nothing.

    I recall there's there's a procedure for putting the top up manually in the Owners Handbook. I assume you can reverse the procedure.

    There's also a tutorial on the forum on how to convert the top completely to manual.

    Cheers

    After the beep, you depress the console toggle switch or it's still depressed?
    You've check & tried to move the cross-bars manually toward the back? (If the elastics don't work)

    try the override switch on the pump/reservoir console. You pop out the button cover & it's there (also shown in the manual)

    All of this is a bit above my grade.

    I only got one manual which I believe only shows some basics operation.

    Check the hydraulic fluid and the straps.

    If the straps haven't been replaced in awhile that could do it. Same with the fluid level.

    Based on your reports, there could be issues with the micro switches. This plagues early Ferrari auto convertible operations as well as Porsche, Mercedes, etc. Best to take to a shop at this point since you can also harm other components with your attempts.

    Try what clyde and Bob are suggesting. Look at the elastic straps right above your head on both sides. They pull that bar back after you unlatch the top and push it back and allow the top to fold. It will bind if the straps are weak. So push the bar back manually after unlatching. Check fluid level.

    I did try to "help" the hydro system quit a bit already. As for fluids the systems works fine to close it back.

    Dont push the top back from the front. Just the bow that the elastic strap is attached too. That bow has to be back for the top to fold. This could be your issue or it could be the seat pots.

    Either way, you own a spider, time to learn how the top works!

    Couldn't figure out the elastic part, part. BUT I tried a few times and both seats started to move a little bit (I already had them very forward) but then nothing. Tried a few time.

    This may help. This picture is from 97 spider's thread on replacing his top. Do you see the small bar that is just in front of the driver headrest? That is the bar that the elastic strap pulls back. There is a strap on each side on the outer edge of the top. HTH.

    Edit: Added one more pic I found.

    Thank you emac. Yes I did push it back and nothing. The PPI report shows top not working probably because of seat sensor.

    Hiya sl55,

    nah, this here about the override for the top...

    "All of this is a bit above my grade."

    ..isn't THAT difficult at all: I sure got two left hands but managed it last week though.

    My top started too but went into beep-beep-mode shortly after due to low level in the hydraulic pump. But these override buttons ("C" for closing and "O" for opening) do not only care s*** for failing potentiometers but also try hard and give everything to operate the top open or close if needs be.

    Just fold both seats to front and you can see and access the override button hole behind the seats from the driver's side - it's just clipped in; plastic tool preferred to pull it out to avoid scratching the leather. Then try to operate the buttons until you have professional help to get at the root of the issue.

    Hope that helps / good luck

    If the top shows no signs of malfunction and there is no beeping, then the top is probably waiting for the seats to be in the proper position. This won't happen if the seat pots are reading improperly. Regardless of position the top "thinks" they are back and is just waiting. Find a tech with the software to read and reset or software allow for replacement of the seat pots and reset.

    If you have the owners manual, the top operation for both normal and emergency, is listed step by step. Section "H" in my manual. If you dont have it, I can email you my PDF of the manual. Just PM me your email.

    Thank you.

    I am wondering if the emergency procedure works for putting the top down and not only up.

    Did you engage the parking brake? It must be on.....I did not see that in your procedure....

    Also, doors must be closed.....

    I got the instruction on emergency procedure and cannot find the "g" bolt the say to introduce to manually close the top

    Also when trying to depressurize the system I turn the screw two turns and nothing happen
