I've been searching and searching but i haven't found any links that point directly to hud trouble shooting. My hud pretty much doesn't work. Sometimes it'll come on but then it kinda fades out. When i look at it from outside the car i see something that looks like a shutter. I also have wierd noises that come from that area at different random intervals and times. Any suggestions? also my driver window goes down fine but wont come back up easily. Any suggestions?
