It's not actually growing, but it no longer fits where it belongs.
The DIC wouldn't stay in place after my accident. I looked inside the fascia, and thought it was because two tabs were snapped off. I ordered another. I attempted to put it inside the new one, but it doesn't fit. the presence of the tabs keeps the display from snapping into place. (It would go into place on the other fascia, it just fell afterward.) In addition, there's now a two inch gap between the fascia and the rest of the dashboard.
I'm starting to think the previous owner deliberately snapped off the tabs to make it fit. There are four screws at the bottom which will hold it in place. If I don't get an answer from someone, I think I'm going to break things myself.
I can provide pictures if needed.
