Here's a breakdown of how to troubleshoot and potentially repair:
1. Diagnosing the Problem:
* No pump sound at all: This points to a complete motor failure (burned out, seized), a blown fuse, or a faulty relay.
* Weak pump sound or sputtering: This suggests a failing motor (brushes wearing out, internal mechanical issues), a clogged pump, or a low fluid level (though you'd likely hear sputtering then silence).
* Pump runs but doesn't pump fluid: The problem is likely a clogged nozzle, hose, or the pump itself (internal blockage).
2. Troubleshooting Steps:
* Check the fluid level: Sounds obvious, but an empty reservoir means the pump isn't the issue.
* Check the fuse: Consult your owner's manual to locate the fuse for the washer pump. Replace it if it's blown.
* Check the relay (if applicable): This is less common, but some vehicles use a relay for the washer pump. You might need to test the relay with a multimeter or replace it if suspect.
* Inspect the hoses: Look for kinks, blockages, or disconnections in the hoses leading from the reservoir to the nozzles.
* Check the nozzles: Make sure the nozzles aren't clogged. Try using a thin wire or compressed air to clear them.
3. Repairing the Pump Motor:
If the motor itself is faulty, repair options are limited and usually not cost-effective:
* Replacement: This is typically the best solution. Replacing the entire washer pump assembly (motor and pump combined) is often easier and cheaper than trying to repair the motor. You can find these at auto parts stores, online retailers, or junkyards. This requires some basic mechanical skills involving removing the old pump and installing the new one.
* Motor repair (Advanced/Not Recommended): Repairing the motor itself involves disassembling it, which could be difficult. This typically involves replacing worn-out brushes (small carbon components that create electrical contact within the motor). Unless you have experience with small motor repair, this is usually not practical.
In summary: Don't try to repair the "reservoir motor" directly, because there's no motor *in* the reservoir. Focus on troubleshooting the washer pump motor and replacing it if necessary. If you're not comfortable with automotive repairs, it's best to take your vehicle to a qualified mechanic.
