Ever so slowly, over the past few months my HUD has been sinking into the dash. It finally got to the point that I would have to press my face almost against the windshield to be able to see anything, so I took advantage of the cool weather and fixed it.
This is a common problem with the C5 corvette, and there’s a good writeup on the common cause and how to fix it on the Corvette Forum. I love that site, by the way. Tons of info, technical and not, a great community, and an awesome source to find peoples take-off parts.
This is what it looks like once you get out all of the dash components. Luckily my girlfriend’s roommate was out of town this weekend, so I was able to temporarily store the parts in her living room. LPT: Don’t do that. It’s a great way to get in the doghouse, and fast.
Here’s the actual HUD taken apart, and the tools used to get it back together. I took a good number fewer of pictures than I probably should have while taking everything apart. Luckily most things only fit in one way, so getting it back together wasn’t too bad.
The mirror that reflects the display onto the windshield is held in place with a pin on one side (this is typically what breaks; and did,) and a washer/pin combination on the other. Unfortunately this was also broken, but disintegrated to the point I couldn’t figure out what it looked like originally. Using layers of clamshell packaging and permanent adhesive, I was able to fashion a piece that would function as a washer/pin combo that would hold this side together.
“It’s only temporary unless it works.”
On the other side the pin was broken as well. I was able to drill it out and replace it with a steel nail, cut to length with the Dremel.
Finally got things back together, only a few days later than planned (but before her roommate killed me for all of the junk in their living room.) Very happy it worked first try. All of the modules are still unplugged, so the dash lights up like a Christmas tree.
