With both of them failing at the same time, you might suspect a fuse. Take the lid off the fuse box and look at the inside of the lid. Often there is a diagram there to show you which fuse to check. If the diagram is not there, it may be in the owners manual.
I hope it's that simple.
Good luck,

Yes their are two seperate pumps. The pum is located in the driver wheel well.
Check fuses then check the pumps. Make sure you are getting voltage to both pumps.
