So I went out to my vehicle today and started it up and I no longer have the Heads Up Display on the windshield. I tried holding the dim button up to see if it would turn on and nothing. I also held it down and still nothing. I looked in the manual and there is no fuse that says it is for the HUD. Has anyone experienced this at all, and how do I even start to troubleshoot it? From what I can tell, everything else is working just fine.
