I check for a B-pillar switch which my model (2002 Boxster S) doesn't have.

I think you can buy metal gears but I figured Porsche made them plastic as sort of a weak link to start with the videos I found just by googling replacing boxster top transmission or something like that.

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.

I'm still not sure what the top transmission switch looks like.
Hello all,
I have a 2001 986 that I converted the top to a manual operation. It works great and I can have it opened/closed faster than the auto operation. However, the top light is on and it won't go off. I tried holding the closed button for a few minutes but that didn't do anything. Any thoughts on how I can get the light to go off?
Thanks,
Bryan
The switch that activates the warning light is in the left side roof transmission. Just jump or short the wires in the connector. Brown-Black to Brown:
Here's my old post:
http://986forum.com/forums/550374-post2.html
When you say the "switch is in the left side transmission", do you mean behind the transmission? I pulled the transmission off the drivers side but I do not see the switch anywhere around or behind it. I don't think it's actually inside the gearbox since there are only a few 22awg wires going to it. Where exactly is this switch located?
I got it. I didn't realize it was actually the 22awg wires going to the transmission that was in your photo. I jumped the brown and brown/black wires and the light went out. Thanks for your help!
The wires connect to a micro switch which is a top position sensor. In the movement position, it's open--so that the motor runs and the dash lite is lit. At either end of the tranmissions travel, it closes. You want to fool the system into thinking that the top is either open or closed all the way. So you jump the connector as shown below.
Hey guys,
I'm having any issue here and I'm a little confused. My top dash light won't go out when I put the top up and clamp down the shell but it turns off when the top is totally down. What is the issue? I can't find any transmission sensor and I'm a little confused by "jumping or shorting it". How do you do it? This light is driving me crazy. Any help would be appreciated!
Jumping the pins only applies to manual tops. Probably a bad idea if your top is still powered. You either have a bad transmission micro switch, or one of the top latch switches.
There are microswitches in the latch. Seems like one of those switches is your problem, or a couple solder joints within that latch.

Dj could also have a transmission starting to go out. Mine did that for a while before it finally failed. The left side where the switch is located could have a gear problem while the right has enough push to get the top to the point where you can close it. At least with mine it started working erratic jerking and such. It took mine about a year to finally go once the light quit working as it should
Hey Particle,
Checking things out. Went over the latch switch and it looks ok. I check for a B-pillar switch which my model (2002 Boxster S) doesn't have. Can anyone confirm this? From what I read, this switch sends a signal to the relay that the top is closed. I'm still not sure what the top transmission switch looks like. I did a search and haven't come up with a photo...
Hey Piper,
Thanks for the Vid! It's ironic, I discovered this guy this week. He has a lot of good stuff on his channel. I check the latch and there was a little corrosion but working. Funny, it only had one switch, the one that drops the windows. Again, mine is a 2002 Boxster S.
Hey Ben,
Interesting stuff. This sounds like my issue because it makes a different noise than what I'm used to on the side of the transmission. It's kind of stuttering slightly to close. Thanks! Is the transmission switch located on or close by?
I think that the change in the design was in the 2000 model and later.
The 2000 and later models have one switch in the latch, a different relay module, and the transmissions are different with the 'B-pillar' microswitch internally rather than on the B-pillar.
Here's a copy from an
old post
that shows the transmission and microswitch location.
That second picture shows the internal switch. The white plastic gear is the one that fails. Mine was literally cracked in half it will still work because it’s packed in there so tight. On mine like I say it was a gradual failure. First the light would not go out. Then it started making noise and jerking a little. Eventually I quit using it for fear of the top getting stuck halfway when I was not home. I took it apart last winter and fixed it. It has worked better than ever since. The write up in the 101 project book has some good photos. I also found a video online. If do decide to take it apart be sure and mark everything with a felt pen so you can get it all back together the same way.
Well, I have all the symptoms of what you're stating. How did you manage to fix the cracked gear? I'm not sure if I would do a rebuild but I am curious to see the video if you don't mind posting it...I appreciate the help!
I bought 2 new gears on eBay and replaced both sides. They came in a set. I think you can buy metal gears but I figured Porsche made them plastic as sort of a weak link to start with the videos I found just by googling replacing boxster top transmission or something like that. It’s been a while and I turn 63 tomorrow so I don’t recall details like I once did
. It’s not that bad of a job. The 101 project book does a pretty good job of describing how to remove replace and time the transmissions. The video I found was about taking them apart and putting them back together.
