What to Do When the Buick Excelle Wiper Fails Intermittently?
4 Answers
When the Buick Excelle wiper fails intermittently, first identify the faulty part before taking corresponding measures. The specific steps are as follows: 1. Check the wiper motor. Open the car hood to locate the wiper motor. Touch the motor by hand—if it feels hot, it indicates an internal short circuit, and replacing the motor will solve the issue. 2. Inspect the wiper blades. If faulty, promptly replace a set of wiper blades. 3. Examine the wiper linkage. Observe the wiper's operation to determine if the linkage is faulty. Replace the linkage if necessary. 4. Check the wiper fuse. Verify if the fuse is blown. If it is, replace it with a spare fuse from the car. 5. Test the wiper switch. Use a multimeter to measure the switch's functionality or directly replace it with a new one for testing. 6. Inspect the wiper wiring. Use an automotive multimeter to measure voltage, resistance, and current to locate any wiring faults causing the wiper malfunction, then replace the faulty section.
I often drive a Buick Excelle, and last time the windshield wipers were acting up intermittently, which was really annoying. At first, I thought it was a minor issue, so I opened up and checked the fuse box to see if any fuses were blown—they're usually located under the steering wheel. Then, I unplugged and reconnected the wiper motor's connector to test if the contact was loose. Sometimes, dust buildup causes intermittent failure, and wiping it clean with a damp cloth before resetting can fix it. But in my case, the relay had aged. During rainy days, the motor's load increases, and the relay contacts got burnt out, leading to a complete failure—only a replacement would do. I recommend keeping spare parts handy before the rainy season. If DIY doesn’t work, just head straight to the repair shop to save time. After the fix, the system became much more stable, avoiding the awkward situation of blurred vision during heavy rain.
After driving this car for many years, intermittent wiper failures are often caused by relay or motor overheating issues. The internal copper contacts in the relay can corrode from moisture, leading to poor contact when aged, causing the wiper to stop under heavy load. The inspection method is simple: turn on the wipers and listen to the motor sound—if it starts and stops intermittently, it indicates an unstable circuit. Also, check if the fuse is blown, usually located near the headlight box. Replacing the relay yourself is inexpensive, with parts costing around 20 yuan, but if the motor is faulty, it needs a full replacement, which is more costly. Don't underestimate this issue—wiper failure during heavy rain on highways can lead to accidents. I regularly clean the wiper blades and remove oil film from the windshield to extend the system's lifespan. Safety comes first—address any issues immediately upon discovery.
My Buick Excelle's wipers sometimes work and sometimes don't, which is especially dangerous in rainy weather. Simple solution: First, avoid using the high-speed setting immediately; try manually lowering the speed. Check if the fuse is intact—its location is marked with a wiper icon in the engine compartment fuse box. Then, shake the wiper arm base to see if the connecting wires are loose; if they are, press the plug firmly. If the problem persists, the wiper motor switch might be worn out, and it's better to take it to a professional repair shop. Remember to inspect it once before the rainy season to prevent issues in advance.
