996 Cab top operating slow - fluid is full
All,
my 1999 996 cab top is working but it raises and lowers extremely slow, sometimes stopping and requiring me to release and again press the button to open/close the top.
A couple of months ago I filled the reservoir which was a bit low and the top worked great but recently it started to act up as above and opening/closing slow. I checked the fluid and it is still full above the + marker. I have not found any leaks. Any ideas on what to check next?
Thanks!
George

Low battery would seem like the obvious culprit. Put it on charge overnight and try again. If all is normal then get pep boys to check the battery free for you. It may be loosing it's charge over time. They last 3 to 5 years tops.

Does it change when the car is running vs. not running (this would help you determine if it was the battery or not). Also, does your car have an aftermarket auto-top add-on? I had one, not the smarttop, but a different one that goes in the dash behind the open/close button. This was nothing more than a timer and never seemed to work right for me... worked better once removed and I never had to guess if it was going to finish closing or not!

Good advice so far. I would follow up on the above items first.
The next thing I would consider is a bad hydraulic pump or pump motor. Has the sound of it changed significantly since this issue has started to occur?

turns out it needed some more fluid. i was looking at it with the top up instead of in the service position. Which is different. I guess this means I have a small leak somewhere since I filled it a few months ago as well...

Possible leak on both or one of the pistons which raise and lowers the roof. You can have yours refurbished. Easy to check when in service position. The lower end should be wiped around with tissue for the leak.
