@TruckGirl i just re-read this thread again and upon arriving at the last message, realize that was me about a year ago. Still having the same issue. It’s an ankle biter, because only use it when the kids want “vacation mode” which happens only occasionally. I tried re-seating the fuse under the steering column - no luck. Tried pulling the console and broke the tabs in the process (word of caution, folks: be careful with the tabs!). Bought a used “working” overhead console from a parts place to no avail. It was the same part number, but from a newer truck. No joy- but I don’t know if the switch was actually working when I got it.
As others have discovered, the glass panel motor and the sunshade motor work. If I hold the “down” side of the VENT switch past roof and shade being closed, and continue to hold it, it will continue to cycle the shade open. If I keep holding it after the shade is completely open, the panel tilts and retracts. If at any point during this very long holding of the switch I release it, either the shade or panel will stop. If I resume the long press mid-cycle (either shade or roof not all the way open, which always has to happen in that order), the cycle will reverse until the roof and shade are completely closed again.
The obvious culprit seems to be a busted switch panel with the only working function being the aforementioned “safety” closure. I’m only guessing, though. My local dealership last year didn’t recognize it as a common problem, but I am starting to have my unfounded doubts about how rare the problem actually is.
My next troubleshooting/diagnostic step is going to be to buy a new switch (just the little box with four buttons) that installs inside the overhead console. It was a pain to get the console open using about three small trim tools simultaneously to pry it open after removing 4 small screws (T-9). Once the console is cracked open, the switch itself is easy to replace with a few more T-9 screws and careful prying. If I recall correctly, the switch is about $65 new online, and about $50 on eBay. The part number on my switch is 6EM26TX7AC.
Fortunately, I drive something else daily (52mpg plug-in hybrid - yay - way better than the 14 on the truck)… and can leave the truck torn apart until I figure it out. At this point it’s curiosity and the principle of the matter.
PS. I don’t think the new switch is going to fix it, but am working from least expensive and time intensive to most.
