Porsche Boxster 987, couple of problems....

[muzzy1]

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.

Thanks!

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?

On this car is there a spoiler switch in the footwell below the fuse panel?

[RFM]

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.

[muzzy1]

Yes that's right its located next to the PSM button under the Climate Control unit. I checked the wiring diagram and apparently there is one only meant to be one connector behind the unit........so why is it not working??

[RFM]

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?

I recently had the center spoiler switch fail too. What is the solution ?

Curious? Any resolution to this by anyone? Thanks...

[jim_hoyland]

I just noted that the passenger well 12v lighter-plug is not working too; any thoughts on how these could be related ?

[jim_hoyland]

The fuses for the lighter and plug were bad. Replaced both; the manual spoiler switch still doesn't work....any ideas ?

[jim_hoyland]

Finally took my 2006 987 Boxster to local Indy. He used the PWIS to test the spoiler. It works. The switch in the center console could be the problem; any thought on this ?

Who sells that switch ? $$ Any idea of cost

If it is in item 13 then Porsche only sells the whole panel. About $135 with you interior color needed.

[jim_hoyland]

Yes, part thirteen. Mine has two switches on that module; PSM and Spoiler. Part number?

Does the centerconsoelhave to be disassembled in order to pull and test the switch ?

Part number is by interior color.

This Switch ( 997.613.133.00 FMH) is called a PORSCHE STAB SWITCH

i found Sunset Porsche in Oregon has the best price, around $106

 

[jim_hoyland]

Got my Stab Switch today from Sunset Porsche in Oregon.

Now for the hard part; getting access to remove the old switch out….any tips ?

[Loren]

[jim_hoyland]

There are 2 other versions of the Stab Switch depending on your cars options. When I submitted my order, there was a box to fill in my VIN. Based on the VIN, parts department selected the correct module with just the switches for the Spoiler and PSM..

Sunset Porsche Parts really helped!

[jim_hoyland]

The Stab Switch has 8 pins; I went over to a reliable Indy to see whether a switch can be tested. He recommends I switch out the old one and see whether the new one will operate the spoiler. If it still doesn’t work, the it’s something else. Per our discussion, the switch sends a low voltage square wave signal to the computer up front; then, a signal is sent to the spoiler motor. Yikes !

I’m thinking; if the PWIS was able to operate the spoiler, then part of the circuit must be ok.

I still have to change switches……..

I’m still curious what others have encountered ( 987, mainly )
