This morning I noticed my rear window was incredibly dirty. I pressed the lever to the nozzle in my new-to-me Cayenne to clear it out. I heard a popping noise..and noticed fluid dripping out of the upper panel closest to the tailgate (interior). Does this panel just pop off? should I remove the light first? Don't want to do too much damage here, everything seems dry now. Haven't tried the rear nozzle again though...but it did end up working.

I guess I just want to avoid another flood, I plan to remove the panel, remove the nozzle, and test it to see if there are any further leaks or maybe I just cleared out the blockage.

Thanks

Same issue, I tried sticking a needle in there to clean it out to no avail, and just haven't bothered to try to figure out how to remove it completely.

thought about trying to tackle this again, removed the interior panel part-way, everything looks inaccessible behind metal..looks like I would have better luck removing the top of the rear spoiler, thoughts?

There was a TSB on this for Gen 1 Cayennes. The updated nozzle is red.

It does have a red nozzle, I'm thinking the line may be cracked? As it will stream out of the back, but also leak into the rear cabin top.
