I took a quick look at the part and it should be easy to change. If you have any experience at soldering here is how I usually pull relays out.
Clamp the board in a vice very gently or have someone hold it. You need two four hands for this.
Puddle some solder over the contacts as you gently rock the relay. One pin may release a tiny bit and then solidify quickly. Just try to run the heat around until you manage to get it to wiggle out. Grab some old lamp wire or any stranded wire and heat the solder and stranded wire flattened out a bit. It will suck the excess solder.
If you can remove the board and hold it in your hand, just heat the solder and shake the excess off by tapping the board. Make sure you give it a good shake. You don't want the solder to slide over to other places.
As a technician wearing levis I would actually slap the board on my leg. Plenty of cushion and the solder comes off the levis just fine. Don't do this with nylon pants.
If you end up with some plugged holes, grab a pin or needle, heat the hole and shove the pin into the hole. Let it cool a couple of seconds. Even if the holes appeared to come out clean inserting a needle or "dental pick" will open the hole for the new part.
