The reservoir does not need replacement.
First check for burnt fuse.
Next check if the washer motor terminals are securely connected.
If you want to test the motor connect it to the battery and see if it works. If the motor is fine then this is a wiring fault.
The motor may also be clogged with things like small bits of paper etc.

Just behind right rear tire up in the wheel well. Air inlet is inside right rear quarter near the accessory inflator. Compressor runs 3 lines one for the accessory inflator and one for each air bag.
THere are also 2 sensors, one on each trailing arm that senses load and then raises and lowers accordingly.
