blinker relay will not stop clicking even when blinkers aren't in use.

Flasher Relay "clicks" when signals not on.

Blinker noise comes on & goes off randomly, but not the blinkers. However, the blinkers do still work correctly when needed. Have not found a solution yet, but sounds like a relay or switch replacement is in order.

blinker clicking noise randomly continues or comes on when blinkers are not activated. Also electrical buzzing noise from column periodically.
Sounds like the flashers are on, but no lights. Clicking noise stops when I press the brakes. Replaced the relay and the brake switch. Is it the multifunction switch? I'd hate to change it for nothing.

Electrical problem when using turn signals, it varies on which turn signal is going work or not, sometimes when I switch turn signal on the flashers come on instead of blinker, also making a clicking sound
