the pumps are generally below the reservoirs.
But, can you hear the pump whirring? If so, the line is clogged or iced.
If not, check voltage @ pump. If ~12v, and connections are good, pump may be broken.
And, of course, check the fuse for this; locations in owners manual.
Lettuce know and we can go to next step.
