Common Issues with the Chevrolet Silverado 2500 HD Towing Mirrors
The Chevrolet Silverado 2500 HD towing mirrors allow you to see around the large trailer attached to your truck. Because your vehicle's stock side mirrors do not provide much view, using it even when you are towing a huge trailer will endanger you and your passengers. With towing mirrors, you can extend them out much farther, so you will be able to see behind your trailer. However, this component is not perfect and it is bound to go bad as time goes by. Should you encounter any of its common issues below, it is best to be armed with knowledge on how to deal with it correctly.
Towing mirror glass is vibrating
Over time, you may notice the glass in your towing mirror starting to vibrate. You will first see it shaking when it is extended, but then later find it also vibrating even when it is retracted. Sometimes, the shaking can get so bad that you can no longer make out what kind of vehicle is behind you.
If this happens to you, simply take out the glass and tighten the plastic retainer behind it. However, if your towing mirror is powered, then you can't do this trick. If the first quick-fix can't apply to your component, then look for a hole with a screw at the bottom of the mirror. This hardware is responsible for keeping the glass mounted. Tighten it using a screwdriver and test if that does the trick. If it still vibrates, then perhaps it is not the towing mirror's fault and you will need to get your tires balanced out. It is also possible that a bug shield or the headlight deflectors on your truck may be the cause of the vibrations.
Towing mirror does not move
As already mentioned, the prime difference of the towing mirrors with the stock side mirrors is that the first one can extend farther for you to see what's behind your truck and your trailer. However, if your mirrors are not moving at all, then there might be a problem with the fuses or the relays. Look for a blown fuse and check for any ground connections. Have the button panel examined to see that the connection is secure as well. You may also need to replace the switch.
