Diagnosing the Issue
If your 2011 Silverado reverse lights have stopped working, there are a few things you can do to diagnose the problem.
Check the Fuse
The first thing you should do is check the fuse. The fuse is the most common cause of reverse light failure. Here’s how to check it:
- Locate the underhood fuse block on the driver’s side of the engine compartment.
- Remove the cover by pressing the two tabs and lifting it up.
- Locate the reverse light fuse by referring to the fuse diagram on the underside of the cover.
- Inspect the fuse to see if it is blown. If it is, replace it with a new one.
Check the Switch
If the fuse is not the problem, the next thing you should check is the switch. Here’s how to do it:
- Locate the switch on the transmission case.
- Disconnect the electrical connector from the switch.
- Connect a test light to the connector.
- Put the vehicle in reverse and see if the test light illuminates. If it does not, the switch is faulty and needs to be replaced.
Check the Lamp
If the fuse and switch are not the problem, the next thing you should check is the lamp. Here’s how to do it:
- Remove the lamp from the rear of the vehicle.
- Inspect the lamp to see if it is damaged or burned out. If it is, replace it with a new one.
- Connect the lamp to a power source to test it. If it does not illuminate, the lamp is faulty and needs to be replaced.
