So my top has started to slow in both opening and closing. As it is bydirectional, consistent through the operation with no notable binding, and the motor sounds like it is struggling, I imagine the first step would be to lubricate all of the various hinges within the top to try and lessen the effort required by the motor to cycle.

Has anyone ever done this? If so, what type of lubricant did you use? On the flip side - if this is an incredibly bad idea (and I can't see how it would be), please explain why.

If anyone has other thoughts as to why my top is struggling to open/close I am all ears.

Thanks for any insight/expertise.

Have you checked the fluid level? They can get low and get some air in them and it will make them slow...I have never lubricated any conv. top parts on any make of car...Slow tops are usually a hydraulic issue...Jason

If there is air in the system, is there a process through which to bleed this out?

No, just check the fluid level in the reservoir...Most Conv. top systems will seep a little over time and lose a little bit of oil...Over time it can add up and the system can get low on oil.....Start there..J

Finally got around to this. Top unit was low on oil, but not by a tremendous amount (1/8" below min line) - filled to max line and tried to operate. Currently I am blowing the 30amp top pump fuse. This happened once before and I just assumed it was a high current draw from the pump due to something needing lubrication (and later figured it could be due to the fluid level being low).

Suggestions outside of a new unit? I have seen threads for F355s where the pumps were flushed. Not sure if that process may help here.

That's the right stuff. My guess is that maybe a valve isn't opening, but then you'd think you would have a problem at some stage of the cycle. Don't take it to a dealer, take it to a convertible specialist.

my thought is that there is some internal resistance/short in the pump motor that is causing the issue. I will play around a bit when I have another fuse (unplug pump and press switch to assure its not a short in the circuit, cycle top manually to try and see if I can force any air out, etc) Any other suggestion is appreciated.
