Good morning everyone,

I checked - the plug is tight. I pulled it off and treated it with contact spray - no improvement.

The fuse box under the hood looks good. Checked all the fuses - each has 12.15 v.

Nothing smells burnt.

Everything on the car works - except the panel.

...will first remove the dirt under the panel


Thanks!

Having 12 volts at the fuse is one thing, but have you actually checked if there is a blown fuse?

Also a very close look at the connectors under the fuse box ...

Are you checking both sides of each fuse ? There needs to be 12V passing through the fuse !!

Another simple check is to try opening & closing windows with Nanocom (you have bought one I hope ??)

ok, the problem is solved for the time being.
unfortunately I didn't proceed systematically.
what I did:
- pulled out all fuses (including those in the engine compartment)
- checked - all fuses were good - treated with contact spray
- Checked the cables under the passenger seat and the plugs

Then the test and the buttons work again.
I suspect that pulling the fuse under the passenger seat solved the problem.

Thank you very much!!!
