Perhaps a 2nd hand Module / a couple of micro switches and a recab may be all you need.

I've been doing a bit more reading and experimenting. The main problem that I face at the moment is that although VIDA can read all of the values of the switches and sensors/potentiometers in the roof system - to program it you need the old Volvo Scan Tool (VST). If you replace the roof ECU, sensors or do any work you may need to recaliberate the roof for it to work properley.
I don't know much about the Volvo Scan Tool - are there any other third party systems that can do the same job? I gather that as it was proprietory Volvo hardware (not PC based) very few people have them outside of the dealer network. |

C70 roof problems
If I were an engineer, which I Am not, I would be looking at it from a completely manual point of view.
Electronics and computers = big bucks for main dealers and problems for DIY mechanics. How much effort would it have been for Volvo to design a robust manual system instead of the flimsy two tool operation we got. Colmac |

Even the SC901 stereo knows if the hood is up or down and adjusts the feq accordingly.
What chance do you have.

The pinouts and colours of the wires are documented in VIDA. When the Roof is down it changes the eq on the SC901, disables the rear heated window, disables the air con compressor and switches the fan off if it is in auto mode. Hoping to get a good weekend on it soon so I can bore you all with my findings. |

Mine is a 2013 hardtop, It goes down fine, but when I tried to put it up the other day the trunk latch sensor was not sensing that the trunk was closed and it wouldn't let me close it. It was definetly closed. After quite a while of opening and shutting the trunk and trying two different key fobs to see if the trunk latch worked (it did not with the fob) it finally sensed it was closed. And I was able to put the top up as usual. Now I'm scared to put the top down. We have no idea how to put a 2013 hardtop up manually despite calling the dealership and searching the web. A sensor problem maybe? Any idea how much it would cost to fix a sensor for a trunk latch, there are no other problems within the car that I've noticed. Is it as simple as a fuse? I wish.
