Controller Vibration Test
Trigger your controller's rumble motors and check both still work.
Controller
none detected
Vibration is only exposed over USB for many controllers, and a Bluetooth pad that rumbles in games may stay silent here. That is a browser limitation rather than a fault.

How to use the vibration test
Connect the controller, press a button on it so the browser can see it, then trigger each motor in turn. Testing the strong and weak motors separately is the point: games mix them, so a failed motor is easy to miss until you drive each one on its own.
What the two motors do
Most controllers contain two motors with differently weighted counterweights. The heavier one produces a low, deep rumble and the lighter one a faster, higher-frequency buzz. Between them they cover the range of effects a game asks for, and each can fail independently.
A motor that produces a rattle rather than a clean buzz has usually worked loose from its mounting, which is common after a drop.
Browser support is the usual reason nothing happens
Vibration is exposed through the Gamepad API's haptics extension, which Chrome and Edge implement and Firefox and Safari do not. Many controllers also only expose rumble over a USB connection, so a pad that vibrates perfectly well in games over Bluetooth can be completely silent here.
Because of that, silence in this test is not evidence of a fault on its own. Confirm in a game over a USB cable before concluding the motors have failed.
Frequently asked questions
- Nothing vibrates. Is my controller broken?
- Not necessarily. Browser vibration support is patchy: Chrome and Edge implement it, Firefox and Safari do not. Many controllers also only expose rumble over USB, so a pad that vibrates in games over Bluetooth can stay silent here.
- What is the difference between the strong and weak motors?
- Most controllers have two motors with different weights. The strong one produces a low, heavy rumble and the weak one a higher, faster buzz. Games mix them, so testing each separately shows whether one has failed.
- One side vibrates and the other does not.
- That points at a failed motor or a disconnected lead on the silent side, which is a common fault after a drop. Test each motor on its own to confirm before opening the controller.
