1998 Dodge Caravan blower motor relay

Heater problem
1998 Dodge Caravan Front Wheel Drive Automatic 150000 miles

I am trying to fix a 98 dodge caravan 4cyl, auto, a/c. The blower motor only works on high. I was told I need a new relay. I found where the relay is on the fire wall in the engine compartment. I see no clips, screws or rivets holding it in place. I cannot remove it. I do not want to break it by applying more force (since I'm not know for being delicate, that's a real possibility). How do I remove this relay? Is it just in there "snug" or is there a clip or tab holding it in place.

Thanks in advance.
