1. The Reservoir Itself:
* Cracks or Holes: Carefully inspect the washer fluid reservoir for any visible cracks, holes, or damage. Look closely at the seams and the bottom. A small crack can be difficult to spot, so take your time.
* Loose or Damaged Cap: Ensure the reservoir cap is securely tightened. A loose or damaged cap is a common cause of leaks.
2. The Pump:
* Leaks around the Pump: The washer fluid pump itself can leak. Check the area around the pump for wetness or evidence of fluid. This often requires removing some surrounding components for a good view.
* Pump Hose Connections: The hoses connecting to the pump can become loose, cracked, or deteriorated over time. Examine the clamps and the hoses themselves. Pay special attention to where the hoses connect to the pump and the reservoir.
3. The Washer Lines/Hoses:
* Leaks along the Lines: Follow the washer fluid lines from the reservoir to the nozzles on the windshield. Look for any cracks, leaks, or areas where the hoses are rubbing against metal parts. These lines often run under the hood and can be difficult to fully inspect.
* Clogged Lines: While not a leak itself, a clog can cause pressure buildup, leading to a leak elsewhere in the system. Try blowing compressed air through the lines (carefully!) to check for blockages.
4. The Nozzles:
* Clogged or Damaged Nozzles: Clogged nozzles can cause pressure buildup, potentially resulting in a leak. Try clearing the nozzles with compressed air or a small pin. If the nozzles are damaged or broken, they'll need replacement.
5. Other potential areas:
* Check under the vehicle: Look underneath the Suburban for any signs of fluid leakage. This is sometimes difficult depending on the underbody shielding.
Troubleshooting Tips:
* Top off the fluid: Add washer fluid and watch carefully for where it's leaking. This will help you pinpoint the source.
* Use a flashlight: A flashlight can help you get a better look in tight spaces.
* Consider professional help: If you cannot locate the leak after a thorough inspection, it's best to take your Suburban to a mechanic. They have the tools and expertise to diagnose and repair the problem effectively.
Remember to always disconnect the battery negative terminal before working on any electrical components near the washer fluid pump. Also, wear safety glasses when working with pressurized systems or compressed air.
