Top not working.

[Frasta]

Man, intermittent issues are the worst, right? Sounds like your Boxster's playing games with you. If the top worked fine earlier and then just stopped, it could be a couple of things.
First, check if there's any obstruction in the top mechanism. Sometimes even a small thing can mess it up.
Also, inspect the fuses related to the convertible top—sometimes they blow without warning.

If it’s none of that, it could be a faulty switch or a glitch in the top control module. Sometimes these things just need a reset or a quick visit to the dealer for a scan. Just make sure you’ve done all the basic checks like ensuring the top’s fully latched and the parking brake’s engaged.
