Panoramic Roof... no power
 

So, my panoramic roof will not even attempt to open - its been in this condition as bought but the weather was never good enough to bother playing with it.

The fuse is fine, I checked the voltage at the motor and I am not getting a reading when I press the button.

Is there a relay in the system? I searched and this is not a common issue. Any diagnostic suggestions? I tried using the convenience open feature with the windows and no avail - doesn't make a sound.

Is there a way to check the module? Is there any other circuits feeding the control system that could be holding it back?

omerta, how much for a used motor?
may be a way to check since you're getting power through the harness TO the motor, just notihng out of them motor correct?

Used motors are not expensive, I can check them on car-part.com.. but the issue is that I am NOT getting voltage at the harness.

I'm struggling at getting INPA/DIS to work on my windows 8 laptop but once I get that sorted I'm going to see if I can run a diag on the can-bus control module as the next step.

I couldn't find external relays in the wiring diagrams and most of it is in black boxes.

If I could add my 2 pence to this....mine is same now. Missing front motor which is ordered but curtain use to move. INPA comes with 3 errors 91 92 and A2 but refuses to close the curtain. If somebody could upload or PM wiring diagram it would help. I would like to power up both motors to see if they work. If they are OK then must be the modulel
