Percussive Maintenance Again
I mentioned the problem that I had with the air conditioning display on the Corvette requiring "percussive maintenance." It turns out that this is a sufficiently common problem that there is a detailed description of how to fix it at Corvette Forum. It involves removing several parts, and then resoldering the contacts on the printed circuit board. It doesn't look all that hard, but I suppose until tapping the display doesn't fix the problem anymore, I'm not going to put this much effort into it.
