What model/year you have?
I never took out the entire relay. I simply undid one hex screw with a small rachet head on a hand driver. Then using 2 butter knives (or flathead screwdrivers), I squeezed open the relay cover (top and bottom) and removed the inner circuitry.
First remove screw on left side, and unplug. Once you get the butterknives into the top and bottom of the relay, grab the inners with some needle-nose pliers. Note how it came out. Then put and snap the new one in.
