Why won't my Hyundai HR70C-9 vibration system work?

[Felix Branairos]

My 2017 Hyundai HR70C-9 roller runs and drives fine, but the vibration system doesn't work. Pressing the vibration button does nothing, and all the fuses I checked are good. Has anyone known where I should start troubleshooting?

Start by checking the vibration switch and wiring, then the relay/solenoid and hydraulic pressure to the vibrator..

if those check out, the vibration motor or control valve could be the issue.
