Maybe it's not a pump failure and the lines are not clogged, but the little filters where the pumps are inserted into the tank can become clogged especially since both the windshield and headlight washer are not spraying water.
What's the odd on both pumps going out. Have you tried the rear pump? The filter on my windshield pump was clogged, don't have headlight washer so nothing to say there. Just used a little compress air to blow out the filter and lines.
