You need to first diagnose and determine what the issue is. You may simply need to tighten the wiper arm, you might need to replace a linkage, you might need to reclock the assembly. Without knowing what your vehicle is, what style of attachment there is for the wiper arms, and without a hands-on diagnosis (which is important when you're dealing with an issue for which there may be more than one possible cause), it's impossible to give you a definitive answer.
You will have to diagnose what is causing the problem first then we can help you fix it.
I have a 2004 Chevy Blazer that I believe had the same issue as you. The wiper arm has a plastic covering over it. You will need to remove it. I using a a Flat head screw driver pry it off where the wiper arm bends. This will allow the base of the plastic piece to pop off the rear of the wiper arm. You can now take a 1/2" socket and tighten up the nut that is under that plastic covering. That was the solution for me anyhow. My driver side wiper arm wasn't moving at all, but the passenger side was. Hopefully that works for you.
