Default Third brake light not working!

Hello, My 17 year old nephew has been working at a grocery store for the last year and managed to save enough money to buy his first car and he chose a Corvette. I knew he was smart however I didn't realize he was a genius. Lol. Anyhow he is getting it inspected Friday and it has a few things that need attention which I'm trying to take care of for him. It is a 95 and the third brake light is not working. I'm not sure how to get into it to fix it. Any advice would be appreciated. Thanks

There are 4 bulbs in there, so it's unlikely that all 4 failed (although it did happen to a friend of mine). On my car there is a separate switch on the brake pedal for the high mounted brake light. That probably changed over the years, but maybe not. The switch might be out of adjustment.

9 times out of 10 it's the switch.

Had the same issue on my '91. Failed inspec for third brake light. It had been working when I bought the car, and it wasn't the bulb, so I took the drivers seat out (I needed the room to get up under the dash by the floorboard) and found the switch. Somehow the plug for third brake light (if I recall, there was one plug for 3rd, one for the standard brake lights) had worked its way out - I have no idea how - but removing it all the way and re-seating allowed it work again. I had expected to have to replace the switch. I got lucky - you might try and get up there to look at the switch. Visually, mine looked deceptively ok - But I could feel it was not seated all the way when I got my hand up there.

The check of the "single" bulb is I'd think very easy. Through the tag opening and the socket I'd think a relatively easy reach. Access to the SLS is substantially more difficult and if it were a bulb I'd think an 1156 will do. Bulb check 1st!!

UNLESS THE NEPHEW HAS MADE HIS FIRST C4 A ZR-1 !!

It being a later '93+ car I don't believe you'll need to go there, you certainly might but you could certainly at least be optimistic when doing the reach for the bulb socket!!
