Hello Folks.
There is nothing like reviving an old thread.
Has anyone else had an issue with the underhood light? Mine used to work if I hit it. Now it doesn't work at all. I've looked on GM sites for the replacement assembly part number. I never could find it.

Any ideas?

GM part # for the whole lamp assembly is

12450086

I also fixed mine, took it apart the lens and the casing cleaned the brass contacts with sand paper . then i put the box back together and applied dielactric grease to the brass contacts for the bulb only!!! it works like new,,,,,,,,,  loneraider white  2002 ave z71 4x4  ontario/

Try taking it apart. As someone else said, either the bulb is bad or the contacts could be corroded. I had to take mine apart a few years ago. There is something like a big ball bearing inside that rolls back and forth when you open the hood. If that ball is corroded it will also cause the light to not work since it will not be making good contact. I sprayed everything down with WD-40 after I cleaned everything up and haven't had problems since. You also might want to put someone bulb grease in the connector after you make sure that you are getting power to the light.

Thanks for the tip I did mine yesterday

I have an 04 AV and was wondering if it's easy to add the underhood lamp?

Mine was like that too, it would be intermittent.  Cleaned it up and it would work good for awhile, but then need to be cleaned back out.  I ended up removing the ball bearing and just putting a small toggle switch in the the main body of the light near the connector.  Just need to remember to turn it off when you close the hood.  It is controlled by the RAP system so if you do leave it on it won't hurt anything, just drive around with it on.

On my 02 the lamp clips into a hole on the hood, I don't know if the 03s have that hole or not,  if they don't then you won't be as simple as getting the lamp fixture, you would need to find a way to mount it to the hood.  One idea I have had, I have seen white LED trailer lights They are the long skinny kind (a single row of like 5 LEDs each)  I thought of getting 2 of these and mounting them to the hood, or to the firewall area by the brake boaster/ac condensor.  That would look really nice and do similar job.
