What to Do When the Rear Wiper of Buick Envision Doesn't Spray Water?
2 Answers
If the rear wiper of your Buick Envision isn't spraying water, it is recommended that the owner: 1. Check if the windshield washer fluid (glass cleaner) has been completely used up. 2. Determine if there is any sound from the water pump when activating the spray handle (switch). If not, the water pump may have burned out. 3. If there is windshield washer fluid and the water pump is making noise, open the engine hood and first observe if there is any leakage in the windshield washer fluid supply hose. 4. If none of the above issues are present, check if the spray nozzles near the wiper are clogged. If the spray nozzles are clogged, you can try unclogging them with a needle or replace them with new ones.
When the rear wiper of my Buick Envision doesn't spray water, I usually troubleshoot the issue myself. First, I check if the rear window washer fluid reservoir is empty - it often gets depleted with frequent use, especially after long drives. Then I inspect whether the nozzle is clogged; if dust or debris is stuck there, I simply clean it gently with a needle. Loose or cracked hose connections are also common issues - I can check this by opening the side panel in the trunk and reconnecting it if detached. Occasionally, the water pump might fail; I test if the front wipers spray properly - if neither works, it might be a blown fuse which can be replaced by finding the corresponding fuse in the vehicle. But don't forget to check if the control button makes any sound when pressed - otherwise it's safer to have it repaired at the shop. I always wear gloves before doing any repairs to avoid hand injuries, and regularly refill washer fluid to prevent minor issues.
