If that doesn't work, you'll need to access the pump. The pump is on the forward edge of the reservoir. The only way to access the reservoir and pump is to remove the front bumper. This sounds worse than it is, but it does take a helper. There are also detailed instructions through the search feature. Once you've gotten to the reservoir, I'd suggest removing the pump, its held in with rubber gasket rings. When I did this the pump screen was clogged. You should also flush the reservoir, as long as you have it open.
If all this fails, then you may try to gently blow out the hose to the rear wiper.
Check valves are used to allow the single pump to serve both sets of washers. if blowing out the hose fails, clogged check valves might be the problem.
Hope this helps,
