Changing The Bulbs In Your C4 Can Be Challenging If You Don’t Know Where To Look For Them

Step By Step

The little bulbs in the driving lights can be hard to find, unless you know where to look. They’re located under the hood hinges on the inside of each hinge.

It’s easier to see the driver-side bulb from the passenger side and vice versa.

The bulb housing can be removed by twisting it. Be careful not to break the plastic housing by forcing it.

Once the housing is removed you can see the bulb. It’s obvious when a bulb burns out because it no longer has a nice, clean glass.

When handling the bulbs, never touch them directly. The grease from your fingers will severely shorten the life of the bulb. If you need to handle the bulb, use a paper towel or similar material.

To get to the third brake light in the rear bumper, you’ll need to remove the gas door.

Next, remove the gas cap...

...and the rubber drip pan to gain access to the bolts for the light assembly.

Reach in behind the bumper to loosen the two nuts that hold the light bezel in place.

With the bezel removed you can maneuver the light assembly out through the gas-tank opening.

Use a Phillips head screwdriver to remove the back plate on the housing to expose the bulbs. Once again, don’t touch the bulbs when installing the new ones.

With the new bulbs installed, simply reverse the process to finish the job.

The ’84-’96 Corvettes are great cars when everything is running smoothly. Refinements evolved through the entire production run and, by the end, GM had worked out most of the bugs. But problems often arise when you have to replace a faulty part. We receive e-mails almost daily, beginning with “How do you get at…?”

Chris Petris, our Wear and Tear columnist, was doing a light-bulb check on a car in his shop, and we followed along so we could show you his tricks for finding and replacing these small but important items.

While not overly complicated to carry out, changing the bulbs in your C4 can be challenging if you don’t know where to look for them. Armed with this knowledge, there should be no reason to have a dull bulb on your C4.
