Fuel Door & Trunk Release on 2005 Cadillac DeVille DTS

The fuel door and trunk releases don't work. Changed the relays under the rear seat still no activity.

Check the valet switch on your 2005 Cadillac DeVille DTS. You will find the switch inside the glove box.
It worked. You have officially earned genius status. Have a safe and healthy new year!
