The symptoms of needing to replace your windshield washer pump are quite simple. The washer tank will empty of the course of a few days. This will cause the light on your dash to keep lighting up, which is quite annoying. When you go to use the pump it will make a little noise and won't be very powerful. Since the pump is pretty cheap and is easy, I recommend changing it.
Changing your windshield washer pump is probably one of the easiest DIYs I've done yet. Since it had already leaked almost all of the coolant out I didn't even have to worry about draining it out. It only requires a wrench, a screwdriver, and a few minutes. This is definitely one you shouldn't pay someone to do.

Locate the washer tank
Locate the windshield washer tank and unbolt it
1. Locate the windshield washer tank on the passengers side of the engine bay and undo the 10mm bolt holding the tank down.
Unplug the pump connector
Disconnect the pump discharge
Unplug the windshield washer pump power connection and pump discharge
2. Locate the plug on the top of the windshield washer pump and remove it. It has a tab on the passengers side of the pump that you need to depress in order to remove the plug.
3. Once the plug is removed slide of the protective black cover.
4. Finally using a flathead screwdriver, pry off the rubber hose coming from the pump outlet. You are going to want to make sure that the tank is positioned so that the liquid will not leak out. Just move things around till it works. If you look at some of the later pictures you can see the way I did it. (I elected to keep the level sensor plugged in, but if you want to remove it to take the whole tank out, go for it.)
Get out the new pump
The old pump
Install the new pump and gasket
7. Take the new gasket and put some washer fluid on the sealing surface to ensure a good seal. Then install it.
8. Install the new pump. (Take a look at the old screen and pump versus the new one. It is obvious where the weep hole was leaking fluid; I guess it just happens)
This is a simple do-it-yourself job and will stop your washer tank from leaking. After putting it all back together take a ride, refill your windshield washer tank, and wash your windshield a few times!
