Why do the wiper's first and second gears fail?

[VanAubrey]

The reason is poor contact in the first and second gear switches and wiring, so you can check the toggle switch. Here are some details about wipers: 1. Car wipers: Also known as windshield wipers, they are blade structures installed in front of the windshield, composed of a motor, reducer, four-bar linkage, wiper arm spindle, and wiper blade assembly. 2. Function of wipers: Their main purpose is to clear rain, snow, and dust from the windshield that obstructs visibility. 3. Operation of wipers: The rear wiper can be activated by moving the wiper lever forward or backward, which differs from the up-and-down operation of the front wiper switch. Moving the lever forward or backward controls the rear wiper's on/off function, intermittent operation, automatic mode, and washer fluid spray. The rear wiper is the wiper for the rear windshield. Rear wipers are commonly equipped on SUVs, MPVs, hatchbacks, and some liftback vehicles.

I've found that wiper speed 1 and 2 failures usually have several common causes: The most prevalent is aging and rusting of switch contacts—last time I fixed my own car, it was due to corroded contacts causing poor connection. Relay failure is also quite common; it controls the current for speed switching, and once stuck, the low speed won't work. A blown fuse is relatively easy to check—just open the fuse box and replace it. Other issues include problems at the motor end or worn-out wiring causing short circuits. When I handled it myself, I first used a multimeter to test the circuit, checked if the fuse was intact, and then verified whether the switch was functioning properly. For regular maintenance, I recommend periodically cleaning the wiper system to prevent rust and testing it before rainy days to ensure safe driving—after all, speed failure during heavy rain is extremely dangerous. If you lack DIY skills, it's best to visit a professional shop for repairs rather than forcing it and risking damage to more components.

Recently, the first and second gears of my car's wipers also failed, making driving in the rain quite nerve-wracking. The main reasons include poor circuit contact, such as loose plugs, or internal damage to the relay causing the low-speed gear to malfunction. Switch contact points accumulating dust or oxidizing after getting wet are also common, leading to unstable current. The related impact is significant: failing to clear rainwater promptly can easily cause accidents. I quickly tested the high gear to confirm it still works, but this isn't a long-term solution, so I went straight to the repair shop for inspection. Mechanics usually prioritize replacing fuses and testing the switch, as it's low-cost and quick to fix. Safety first, after all. Developing regular maintenance habits, such as cleaning the wiper groove to prevent moisture erosion, can significantly reduce the failure rate.

I believe the failure of wiper speeds 1 and 2 often stems from electronic control issues: modern cars use modules to manage speed settings, and contact corrosion or relay contact sticking can block signals, preventing low-speed operation. It could also simply be a blown fuse that needs replacement. When troubleshooting, I usually start by checking the fuse box and then test the switch continuity. Keeping the vehicle dry during rainy days can prevent rust and extend lifespan; accordingly, I recommend using moisture-proof spray for circuit maintenance. If you notice a malfunction, don't panic—first try switching to other speeds or pull over for repairs.

As an experienced driver, I've encountered the failure of wiper speeds 1 and 2 multiple times: usually caused by switch or relay wear, or a blown fuse. Corroded or loose wiring connections can also cause issues. I usually check the fuse box first, and if it's intact, I'll dismantle the switch to clean the contacts. If that doesn't work, replacing the relay is necessary—it's not expensive, but it's best to go to a professional shop to avoid incorrect repairs. For maintenance, regularly lubricate mechanical parts to reduce friction damage. Before the rainy season, always test to ensure reliability, so you don't end up with impaired visibility during rain, compromising safety.

I have encountered failures in the first and second wiper settings on my family car, with the issues mostly lying in the control components: oxidized switch contacts or relay failures causing current interruption in the low-speed function; blown fuses are the quickest to fix; aging wiring harnesses leading to short circuits are also not uncommon. To save money, I often purchased parts for DIY repairs but frequently ended up wasting money. I recommend prioritizing a reliable repair shop for diagnosis to ensure accuracy. Safety-related: wiper setting failures during rainy days are extremely dangerous. I have developed a habit of checking wiper operation during regular maintenance and keeping the system clean and moisture-free. Don’t ignore minor faults as they can easily escalate into major problems.
