Porsche Boxster 987, couple of problems....

Recommended Posts

Hi everybody! I've just brought a used Porsche Boxster 987 however unfortunately the rear spoiler doesn't seem to work, I've tried pressing the spoiler button and it just doesn't work (the LED does not even light up). Also the the buttons by the drivers seat that open the front/rear luggage compartments do not work, they have to be opened by the key. Any ideas on how to fix this?

Any help would be greatly appreciated.

Ok I removed the panel/unit with the Spoiler and PSM buttons (below the Climate Control unit), and there isn't actually any cables plugged into the socket behind Spoiler button whereas there are cables plugged into behind the PSM button (which is working)......

I'm guessing this is why the spoiler button isn't working. Any ideas?

No, the switch is located just under the Climate Control unit panel on a 987/997. It is a complete unit together with PSM and some other buttons depending on the available options, you will need a wiring diagram to check the wiring's in the single conector.

I would start reading error codes and system check with a PIWIS diagnostic tool, it could be anything as wiring interruption or even missing, control box/relay bad, fuses, spoiler motor or drive, etc.

Hi muzzy1, Any resolution to your problem? I have the same problem with my 997... Cables are connected OK, Fuse is good (because horn and tailgate lock are on the same fuse and working properly) And the dealer can open the rear spoiler with the computer... We suspect that the switch module (below the climate control) is dead... What do you think?
