Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order.

Reported cause · Original poster
The problem is a switch, a relay, a part that swells in heat, and contacts separate.

Suggestion
If you want to dig in a big more, since you said you already replaced the controller, it appears the the engine lid signal is on Pin 8 of the 26-pin connector (brown/red/black --at least in the '99 schematic.).
Leading evidence: 'switch, a relay, a part' (1 discussions report identifying this cause; no attributable repair resolution). Across 1 matching discussions, the most frequently mentioned possible cause is 'switch, a relay, a part' (1 discussions; 1 report identifying it and 0 suggest it). The most frequently discussed action is 'Replace controller' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.

From what I can tell, the switch is integral to the latch and not a separate Porsche part -- though it may be possible to replace the switch within the latch with ingenuity...
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Frustrated. Here goes.
My top, in hot weather, will not close. Doesn't budge. If I put it in the garage overnight, next morning it closes fine. I've had the problem for two years, and multiple occasions, won't close, garage for the night, next morning it works fine.
No hydraulic leaks, new controller, new dashboard toggle. My research seems to have identified the problem, just not the solution. The problem is a switch, a relay, a part that swells in heat, and contacts separate. When it cools, it operates just fine. I've searched several forums and I've gotten far flung and contradictory advice, tried 'em all, including graphite in joints, to no avail. Still lookin' for the solution. I'm sure its simple, but.......
I did a little research on this. This is all just arm-chair diagnostics from a non-996 guy, so consider the source (and price)
It seems the convertible top is permitted to operate only when four basic conditions are satisfied: ignition on, parking brake applied, vehicle speed below 3mph,
and the engine-compartment lid is reported closed
.
Could be just about anything (motor, harness, switches, etc.) but my first guess would be a microswitch in the engine lid latch that confirms the engine compartment lid is closed. Have you tried pressing on the engine compartment lid while pressing the cabin button when it acts up and/or opening and closing the engine lid? You could also try opening the engine lid and spot-cooling the latch with a can of compressed air (sold as keyboard/electronics cleaners). If the top then works once that latch is cooled, it's pretty compelling evidence that the microswitch inside is failing when hot. Since it sits over the engine, heat and heat-related failures seem like a natural.
If you want to dig in a big more, since you said you already replaced the controller, it appears the the engine lid signal is on Pin 8 of the 26-pin connector (brown/red/black --at least in the '99 schematic.). When the lid is closed, that pin is not grounded, and when the lid is open that pin is grounded. So if you are able to back-probe that wire and find that it is grounded even when the lid is closed, that's near-conclusive proof the latch switch (or the harness/connectors to it) are bad.
From what I can tell, the switch is integral to the latch and not a separate Porsche part -- though it may be possible to replace the switch within the latch with ingenuity...
[edited from original to clarify open=grounded; closed = not grounded]
