I have my hood up in the garage most of the time for the battery tender. Light goes off in 10-15 minutes.

Its called the RAP circuit and it times out usually around 12 minutes. Shut the car down with the redio ON and see if it turns off on its own after the RAP circuit times out.

Look in the instrument panel fuse box. Relay 37 is the MONITORED LD relay. That relay controls that light as well as the IP Compartment lamps, the Vanity mirror lights and mirror lights. Check and see if that relay is switching.
Ide say change that relay if it doesnt switch..
If you cant find it locally, contact Gene Culley www.gmpartshouse.com
If that relay is working correctly, the BCM is the root cause and not switching the lamp off

If the relay is bad, Repairing that relay could save you a dead battery. We frequently leave one of those lamps on accidently.
See if you can turn the DIMMER all the way up and turn the lamps listed ON
Please tell us how you make out.

Under hood Lamp
OR follow the wire down approx. 18 to 24 inches and disconnect at the wire junction. It's a simple pull apart plug. Unplug for the show and connect before you drop your hood and go home.

Was about to say the same thing as above, it's pretty easy to reach and disconnect that plug. In fact, it's rare I actually want the light on when the hood is up. But if working correctly it will shut off after 10-15 minutes as others noted.

Good point. Look down by the radiator shroud (passengers side where the harness is and see if its correctly connected to the OEM harness connector.

Funny thing happened yesterday. I opened the hood turned on the sun visor vanity lights, came back 20 minutes later everything was off
I said to myself :stopbeatingadeadhorse:
maybe it's working OK. I put the sun visors up and the under-hood light came on again. Must be something loose some where. Easier to install new switch then to ring out wires.
Thanks for everyone's input and help.

The BCM looks for current draw to turn the lights back on. When you cycled the mirror light switch, the BCM turned the lights back on. Any electrical disturbance will start the timer over again.
Give it another try and see if the under hood light does go out after 10-15 minutes. Mine turns off after 12 minutes but some C5s do it sooner, some take longer.
Another thought. If something in the car is turning on and off (like your seat motors or lumbar pump motor), the timer will never turn the lights off.
