Thank you for your response! I just changed the fuse but its still the same, it won't turn on at all. Any recommendations for this?

 

May be a ground problem. Check grounds underneath plastic door surround on driver and passenger side. Drivers side is close to parking brake petal but under plastic trim.

 

I checked the grounds and they're good but the instrument cluster still doesn't work. Any suggestions? Thank you.

 

This info is for a 2008 N* but is probably the same.
Did you check G101 under the hood drivers side? The other end connects to the IPM- connector X3 pin #3.
and G200 on the left side of the instrument cluster near the a pillar.
Check under hood fuses: ECM/TCM IGN 15 A and EKM/I/P 10 A (may be labeled TCM/IPC)
Hope this helps. Good Luck.

 

Hey I got the same problem, I checked all the fuses the only thing that comes on is the engine light

 

I'm having the same issue

 

Anyone figure this out? Same here. 2009 CTS

 

same issue, 2014 xts

 

all instrument panel lights and buttons went out for me. Everything else works...

Can't find a solution...

 

Anyone figure this out? Same problem?

 

no - they came back on by themselves... Can't understand it...

How long was it not working before it came back on? Did you drive the car while it didn't work?

I have the same problem and decided to remove the ground cable from the battery post for a few seconds and reinstall and the problem was solved for a while. I don't know what causes it but you can instantly reset it by removing the G cable and reinstall it, just incase it happens while driving. If anyone knows what causes it please let us CTS owners know.

 

Just had the same issue in my 06 CTS. Panel and radio went out. A/C and heat quit too. Blower was good but not cooling or heating. Also couldn’t unlock the doors or roll down the windows. I don’t know if it goes back to that recall issue with the key/ignition or if it’s as simple as maybe replacing the cluster panel relay.

 

 

It’s a solder issue. Poor connection. The cluster will need to refurbished or bought new from the dealer.

 

More common in Chevy GMC trucks. all around the same years. Exact same issues. GM just don’t want to foot the bill for a recall. Not sure if they still use the same vendor but around 08-10 it’s stopped being an issue.
