If you are having trouble connecting your Facebook account because it is associated with another Pandora account, you will first need to log into the other Pandora account that is using your Facebook account and disconnect it.  Then you will be able to associate your Facebook account with a different Pandora account.
 
Follow the instructions below to learn how to disconnect your Facebook account from your Pandora account:
 
On the Web
 
Sign in to your account and click on your email address/name in the top right corner.
 
Select Settings, and then Privacy.
 
Under ‘Manage External Services,’ click on Disconnect next to the Facebook icon.
