Disabling Roof Sensors - 1999 Boxster

[bendemora]

Hi All,

I've got a 2.5 litre 1999 Porsche Boxster, and my roof is behaving a bit weirdly. Sometimes, when I push the button to operate the roof, NOTHING happens. Other times, it works fine. There seems to be no clear reason for this. I suspect that it's some kind of safety sensor intended to stop me from messing with it at the wrong time, that's possibly gone screwy. I'd really like to know if it's possible to find and bypass these roof safety sensors? Of course, I'd still need the one sensor that detects the roof cycle complete so that it shuts down the pump at the right time...

Cheers!

There is a pin you can bend down (#17 ???) to disable. It has been covered multiple times, try search. I'd try unseating and re-seating the relay, it is large double sized above your left foot in a US car. Maybe some connector cleaner.

Someone showed me the link to this site and there are some awesome DIY instructions, including the one you're looking for. I'm thinking about giving it a shot myself.

Ah!! bendemora, you seem to be on the same path I am!

I have a '97 2.5litre right hand drive 986 boxster. My problems is I've been hit by the dreaded intermittent dropping windows when the cabrio top is up for quite some time. I've tried tightly securing and cleaning the latch microswitch as per advice in previous threads, but it seems to happen again after some time. Most recently, I epoxy'd the microswitch to the latch recepticle, but it doesn't help despite being firmly in place. I've noticed that the windows do not drop when I remove the cabrio relay, only trouble is, I can't put the top back down until I plug it back in.

To save the hassle of doing this manually, I want to connect a switch from the power supply wire that feeds the cabrio relay so that I can flick it to simulate removing the relay, and putting it back by turning on the switch. Guess that's what you want to try too?

Trouble is, I don't know which wire I should splice the switch to? Using a multimeter, there seems to be 2 supplies at 13.5V and 1 supply at 12.5V with the relay taken off.

I'll probably start a new thread on my problem if it's not the same solution you are looking at.
