Convertible top not working

My convertible top is not working.
Things i've checked
  • The two fuses D3 and B6 are there anymore perhaps one for just the convertibletopengine??
  • Parking light switch is OK.
  • Switch in the roof is OK.
  • The button itself is OK.
  • I've tried changing the controlunit to a new one so that should be OK.

The switch on the left by the seatbealt om not sure its working correct but it should. what is the symptom if its broken, is still giving me either top is up or down ?

I've tried measure power on the convertibletop engine itself.
And here is the wierd part im not getting any electricity to the converitble top engine when i push the button, however im not sure im doing it right?
Is it possible to just measure the black and green cable? there are 5 cables comming in 2 for in and outgoing on the microswitch ontop of the engine.
The last one i don't know what thats for?

So the last thing now to check would be the cables from the control unit to the convertible top engine ??

Am i missing something here?

You might want to pull the motor out and directly apply a 12V source to rule out the motor. I would then check the e brake switch next as it has to be engaged and working to have power to the motor.

Welcome to the club! I started a recent thread on my problems, and it ended up with a lot of good info in it. You might check there. I'm in manual top mode and mostly loving it. It's one less thing to worry about breaking. Just rattles a bit.

There is a switch attached to the emergency brake mechanism that only allows the top to go up or down when the emergency brake is set. It is not that difficult to remove the drive motor to confirm whether or not it is working. Three nuts hold the motor bracket and two clips hold the drive cables. One on each side and the wiring harness.
If you are sure it is not the motor the e brake switch would be easy enough to test next. I am assuming from your post that the motor is not turning at all.
