Disable broken rear window shade
When I purchased my 2011 Cayenne, I was very annoyed to find that both rear window shades were inoperable. Worse, this kept both rear windows from functioning at all - any signal sent their way resulted in the window shades making an awful grinding sound for 10 seconds or so, and no window function. I searched far and wide for solutions to this issue, and most concentrated on restoring function to the automatic window blinds by rebuilding the broken motor inside the door. Since this was a function that I was not interested in having, I was interested in a different solution. I figured it was very unlikely that both rear window regulators had also broken, so checked in on the coding thread to inquire if the rear window shades could be disabled. Forum member JonUF02 was kind enough to check it out:
Today, I was able to visit with my mechanic friend who has a different scanner, an Autel branded professional grade and very expensive one apparently, but the coding was similarly straightforward. Disabling the rear window shade ("roller blind" in the Autel's menus) restored function to my rear windows.
For anyone in this position, this represents a significantly easier and less expensive option to restore function to your rear windows than pulling the door apart and manually repairing the gears in the shade motor. Hoping that posting this here will save someone else some headache! Cheers
@1thenaton1 I verified this coding for you today to eliminate use of the rear sunblinds. Here is the location in the menu of my X431 V Pro (8" tablet version)
Select module for door; rear left or right > Code/brush Hiding > Brush Hidden/Modified > Control Unit Coding > Control unit coding_0 > Control unit coding -- Vehicle coding 2 -- Sunblind
At this point you can set the feature from Active to Inactive, then Write and it disables the rear passenger sun blind. I hit the window button and the shade never moved but the window did. Set back to Active and resumed normal operation of the sunblind with window switch.
Cheers!

Yeah, this was a great fix, even if yours aren't broken. I never really found much use for them.
I found the coding in my Launch tablet yesterday, but the location and verbiage was a tad different... Regardless, I tested it successfully on the one that is working, and it now disabled, and as soon as I fix the other side I'll be disabling it as well.. Then if I ever need them I will be able to re-enable them and they (hopefully) will still be working.

I'm assuming if my scan tool can make the windows go up and down on their own, then the regulator and switch and all that is good to go? I can make them go down with the switch, but I can't make them go back up. I unplugged the power wire to the sun shades because all they do is beat the **** out themselves for 30 seconds like Pac Man.

Ahhhhh no wonder. That thing is like $1,000 compared to all the cheaper iCarsoft & Autel ones I've tried. OK, I'll bite.... Hopefully I can get the window shade motors bypassed so the rear glass goes up and down again manually with the switch. And then that thing goes straight back to Amazon lol.
