Coverage and how to read this overview
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.

So my top will not go down at all. Replaced the top switch (not that) checked the relay and that was fine. But I was wondering if anyone knew where to find this top control unit on a 1999 Porsche boxster? I checked up in the dash in the drivers side footwell and didn't see anything that looked like it.
Hello - take a look at the link below for the location and a convenient fix/replacement.

Yeah I think that switch is definitely going bad, I gotta mess with the latch before the motor starts going. But I still don't understand why on days where it's 70 degrees I wiggle the latch and nothing happens at all till it cools down to the low 60s.My only guess would be the top relay.
So i figured it out....I took out the microchips where the light is inside the car for the windows and the top and it magically started working again. It also did something new, it now beeps twice after you lock the car. Any idea's why this happens now?
Yeah I'm starting to think it's a bad connector or something with the wires. It's always parked in the sun (no shade available) and the wires in there look flat in some spots.
I have similar symptoms as you - roof intermittently doesn't work at all, sometimes seems to be related to temperature.
In my case, it's definitely the part with the two microswitches under the latch. If I take the switch out and fiddle with the switch that senses when the roof is un-latched, I can get it to go - I've just been two lazy/cheap to replace it. One trick I've found is that if I stick my fingernail in the hole where the latch goes and pull down on the plastic flap in there, I can usually get it start working.
