disco 2 sunroof electrical troubleshooting

818 Views 1 Reply 2 Participants Last post by  TCC

My sunroofs stopped working all of a sudden (like many others)...

I replaced the ECU. the fuse is good. I have a test light (vs. a voltmeter) and am trying to figure out where the breakdown could be?

I've tried plugging my test light into the badk of both plugs (for front switches) and there is NO power at any of these points. (I replaced the ECU with another new tested one).

If it's not the ECU, or the fuse, and there's no power at the motors, what else could it be?

Thanks for any input....

I would suggest checking if there is power even getting to the ecu. If not then you can start looking from there.
