Bump
I’m experiencing the same issue in my GTT. I don’t think any of the buttons are stuck and when this problem first started I was driving during one of the heaviest storms I’ve been in and when I turned on my A/C to defog the windows it happened (first controls and clock not working, then after restarting the car only the clock).
I suspect some water got into something it shouldn’t have /fried something ?
The rest of the A/C controls are fine and the clock counting up will go away for a few days/weeks then randomly return. Any help as to how to attempt a fix would be greatly appreciated 🙏🏻🙏🏻
