Nice write up and pictures, I'm waiting for the switch so I can do the repair, do you happened to know how the wires matched up color wise to the switch ?
Leading evidence: 'Replace damaged microswitch' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Repair do you happened' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.

I used the existing mounting bolt and made it a tight fit to pull the microswitches down.

I don't have the wire colors handy, but I used a meter to confirm the proper wires for the new and old switch.

I recently had to replace a microswitch on the rear spoiler of my 1999 C2 996 (cabriolet).
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

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.

Outcome without a verified action link
After reinstalling, the spoiler actuation with inconsistent, and the brake lights did not work properly.
I'm in the middle of repairing my rear spoiler and while reassembling the unit I'm finding the outside micro switch is not secured and moved out of place.
the red line is where the outside switch sit
not staying in in place when I snap the cover on. is there a trick I'm missing to secure them?
Thanks for any help
I recently had to replace a microswitch on the rear spoiler of my 1999 C2 996 (cabriolet). There were multiple failures that required some work to repair, so I thought I'd document it here for posterity. (this thread reminded me about it.) Hopefully this helps someone in the future.
What I think happened: The housing (for the drive gears for the rear spoiler actuation) warped slightly with time and engine heat, causing the one or both of the microswitches to not engage. Eventually, one of them also broke. The microswitches seem to control the travel of the spoiler, as well as the activation of the upper vs. spoiler-mounted center brake light.
Here is the drive mechanism, located on the underside of the engine lid. The two microswitches can be seen on the top of the housing, with wires coming out of them on the right side.
First, I replaced the damaged microswitch. The SAIA-Burgess (Johnson controls) part number V4NS-UL is a direct replacement, but the wire colors are different. I found it at Newark Electronics for about $6 plus shipping.
You need to match up the Normally Open, Normally Closed, and Common wires with the existing Porsche wiring. I don't have the wire colors handy, but I used a meter to confirm the proper wires for the new and old switch. I soldered in the new switch and put heat shrink tubing in place.
After reinstalling, the spoiler actuation with inconsistent, and the brake lights did not work properly. I took it apart again and found that the housing near the microswitch was very slightly warped. The microswitch was not actuating, but I could squeeze the housing with my fingers to get it to work. The gap between the switch and the slider was just slightly too big for the switch to operate.
My solution was to fabricate a small metal bracket with a shim to hold the microswitch down, and reverse the warped housing. I used the existing mounting bolt and made it a tight fit to pull the microswitches down. Note that I had to trim a few millimeters from the plastic housing next to the switches to get this bracket to fit. This has no impact on the operation of the unit.
Put it back together, and everything works fine! Hopes this helps someone in the future.
Nice write up and pictures, I'm waiting for the switch so I can do the repair, do you happened to know how the wires matched up color wise to the switch ?
