Yep, that's the signal relay. If it is tight, chances are it is corroded. Wiggle it gently when pulling. It should come out.
Once you get it out, check the connectors to make sure they are not corroded or damaged. Before you put anything into the plug to clean it, I would disconnect the battery to eliminate the chance of a short.
Take a look at the pic below. It should look familiar. At least now you know where the blower motor relay is too. LOL
Let me know if you get it out and if it takes care of the issue.
