I have a warrant in the state of washington for dui and negligent endgagement. i am living in puerto rico right now.

The extradition laws only apply to felony charges, so you should not be arrested in Puerto Rico and extradited back to Washington on misdemeanor charges, such as DUI or reckless endangerment. Of course, if you return to Washington, you should contact an attorney and make arrangements to see the judge and request that your warrant be quashed. Your attorney might even be able to work out a deal on your case with the prosecutor, which can be entered at the same time you do your warrant quash. There is usually no way to do a warrant quash unless you are present in court.
