I don'e think that has an effect on the courtesy lights.. only Canadian cars had that sensor

I was looking at the wrong light sensor. I now see the tiny sensor directly in front of the driver on the dash. How can I check to see if this sensor is my problem?

When it's outside in the light with the key on cover the sensor the dash will dim

There must be another way to check this sensor rather than assume it's the problem. No lights come on with the sensor in complete darkness. Can I bypass the sensor without harming anything to see if the lights come on?

I don't think that it is the sensor..

Do you own a Factory service Manual for the Corvette?

I still say test things out through the CCM and also check the Courtesy Light relay

I do have the service manual... trying to make sense of it now. Do you know the location of the courtesy relay?

I'd be all over replacing the relay if I knew what a hush panel was....

So you're saying the courtesy relay is on the passenger side under the glovebox carpeted area?
