My HUD quit working, I changed fuse , tried the up,down and bright button with no luck… any help appreciated

 

Try your second remote. My HUD would work sometimes but no all the time then I figured out that one remote had the HUD turned off.

 

Sorry I didn’t tell more My name is Dennis Guillory in Lake Charles, Louisiana and I have a 2005 c6

 

Thank you sir will try that

 

Tried second remote still nothing…

 

Wait for a moderator to move this to the C6 General forum.

Reread pages 3-19 to 3-22, of your owner's manual, especially the right side of page 3-21. Try pressing the + button on the bottom of the HUD controls.

 

Diagnostic steps:

Circuit/System Testing
Ignition OFF, disconnect the harness connector at the HUD.
Test for less than 1.0 ohm of resistance between the HUD ground circuit terminal 6 and ground.
⇒ If greater than 1.0 ohm, test the HUD ground circuit terminal 6 for an open/high resistance.

Verify a test lamp illuminates when connected between the HUD battery positive voltage circuit terminal 1 and the ground circuit terminal 6.
⇒ If the test light does not illuminate, test the HUD battery positive voltage circuit for an open/high resistance.

Verify a test lamp illuminates when connected between the HUD dimming up switch signal circuit terminal 11 and B+ while pressing the HUD dimming up switch.
⇒ If the test light does not illuminate, test the HUD dimming up switch signal circuit for a short to voltage or an open/high resistance. If the circuit test normal, replace the HUD.

Verify a test lamp illuminates when connected between the HUD dimming down switch signal circuit terminal 12 and B+ while pressing the HUD dimming down switch.
⇒ If the test light does not illuminate, test the HUD dimming down switch signal circuit for a short to voltage or an open/high resistance. If the circuit test normal, replace the HUD.

If all circuits test normal, test or replace the HUD switch.

 

At dark, if you look down into the HUD, do you see a green hue? If you do, then that means that your mirror pivot points have broken. You can remove the HUD
and repair the pivot points yourself. You tube video on the repair is available.

 

Incase you don't have your owners manual here it is on the web:

Thank you will try that

 

Thank you so much…l just checked I can see hud inside hole… so next week I gonna tackle mirror pivot points… wish me luck

 

Good Luck - I had the same issue - couple of hints - be sure to cut the duct so that you give yourself enough room but can still tape it back together. Getting the HUD out if I remember correctly - you have to completely remove the nut and then cut a slot will make re-installation easy. I actually repaired the plastic pedestals with some JB Weld and then added the washers which made for a quality repair.

GOOD LUCH - YOU CAN DO IT!!!11
