Alright, so the other day my oil gauge was suddenly pegged out. I immediately remembered seing threads on here about the oil pressure sensor, so i looked up an article and changed this out myself this morning. Oil pressure is back to normal.

This has built up my confidence a little, so now I'm wondering how hard it could be to change out the Heads up Display Unit? Mine sat in the sun too long last summer and hasn't been able to move all the way up on the windshield ever since. I've heard of this happening to other C5's, but have any of you out there replaced the unit yourself? I took a peak under the dash and there are a lot of random wires, etc, things that could easily get "messed up" by an amateur. Anybody done this before? Suggestions?

 

Here are some comments I've seen:

Most likely however, I would suspect a connector being poorly seated as the problem. Requires IP removal only. I would check to make certain the connectors are fully seated on both ends of the 11 wire connector cable.
Good news: If the switch is bad you only need to remove the IP.
Bad news: If the HUD projector drive motor is bad, you'll be pulling the dash pad again and replacing ($$$) it.

I just installed a HUD system in my 2000 hardtop this past weekend.
Once installed, I discovered that when adjusted fully up, I could see only about 3/4's of the display. However by raising the rear leg (point closest to the steering wheel) I could see the display perfectly. It only required raising the leg about a 1/4 inch, and the rear leg is in a slot so raising it this much was no problem. The difficulty is, if this is your only alternative to pulling the display up, you're gonna have to pull the dashboard... good luck...
