Right Turn Light Buzzing
 

On my 97 Ford Explorer, when i switch the Right turn signal, instead of it making the regular ticking noise it just makes a loud buzzing noise and doesn't stop until you turn or switch it off. The lights also don't work when it makes this buzzing noise. I can hold the switch just enough so it doesn't lock in and it will tick normaly and the lights will work.
Anyone know if this is a quick fi or if i will have to take this in?
