Boxster convertible top issues

I know this has been posted before but I'm new to the site and I am having issues with the top. Most times it will not work but on a rare occasion it does. I'm scared to drop the top because I got caught with it down and it would not come back up.
I've read other responses but here is my issue: Windows drop with parking brake up and latch released. Top sometimes works but mostly it does not. I've check all the fuses listed in the manuel with no luck. I do notice my brake light flickers when hitting the brakes then goes off not staying on. Brake light seems to work only when in a certain spot depressing the pedal. I've tried holding the brake down with the brake light on but that doesn't maek the top work.
It is worth it to purchase a rely off eBay and try that or might there be another secrect someone could share.
Thanks

Top - does the parking brake light illuminate on the dash when the parking brake is engaged? If not, it could be the micro-switch.
Brake Lights - could be a dirty brake light switch.
or both issues cold possibly be due to a faulty ignition switch.

I would replace the micro switch at the latch first...usually it is the culprit.

The parking brake light on the dash does not come on with the parking brake engaged. I'll tear that console out to check the switch.

If your parking brake light is not illuminated (by pulling up on the parking brake), the electric motor will not receive power and your top will not operate.

The microswitch under the rear of the parking brake handle can usually be "revived" without removing the entire console. You can usually get it to work reliably again by blasting the microswitch with compressed air and/or electrical contact cleaner through the little opening you will get when you just remove that little side panel on the driver's side rear of the console.

After you have blasted it, test the parking brake a few times to see if the light now goes on reliably.

If it does not, you will have to remove the console for a more thorough cleaning and/ or replacement.

Regards, Maurice.

Here's your fix... I just recently had to do this as well. It's a $5 replacement part, but it is a bit of a pain to remove/replace due to the location of the sucker. You can try first just removing the ashtray and plate under it to spray some compressed air on the plunger in that Microswitch first to see if that fixes it.
