Few things are more stressful than turning on your wipers during a downpour and watching them do absolutely nothing. While a dead wiper motor or broken linkage requires a trip to the mechanic, many common wiper failures can be fixed in minutes with a simple trick.

Before you panic or call a tow truck, try these step-by-step fixes to potentially get your wipers moving again.

The "One Trick" That Often Works: The WD-40 Method
If your wipers are moving very slowly, making grinding noises, or are completely stuck, the culprit is often corrosion or rust on the wiper transmission spindle (the pivot point where the arm connects to the car).

How to do it:

Locate the Pivot Points: Look at the base of your wiper arms where they disappear under the hood/cowl (the plastic panel at the bottom of the windshield).

Apply Lubricant: Spray a generous amount of WD-40 (or a similar penetrating lubricant) directly onto the pivot points.

Wait: Let it sit for 5–10 minutes to break down the rust and corrosion.

Manual Help: Gently try to lift the wiper arm off the glass slightly and move it back and forth by hand to work the lubricant into the joint.

Test: Turn the wipers on again.

Why this works: The metal linkage under the plastic cowl can rust over time. WD-40 helps free up the seized joints, allowing the motor to move the arms again.

Quick Fix #2: Check the Nut (The "Tighten It" Trick)
Sometimes the wipers don't move because they are physically disconnected from the motor. If you hear the motor running (a whirring sound) but the arms are stationary, the linkage arm may have popped off, or the mounting nut may have come loose.

How to do it:

Inspect the Base: Look at the very bottom of the wiper arm where it attaches to the car.

Check for a Loose Nut: If there is a plastic cover, pop it off. You will see a nut holding the arm to the spindle.

Tighten It: If the nut is loose, tighten it with a socket wrench.

Reattach the Arm: If the arm is moving freely on the spindle but the nut is tight, the splines (teeth) inside the arm might be stripped. You may need to replace the wiper arm itself (a cheap and easy DIY job).

Quick Fix #3: The Fuse Swap (The "Electrical" Trick)
If your wipers are completely dead (no sound, no movement), the issue is likely electrical. The simplest fix is a blown fuse.

How to do it:

Find the Fuse Box: Consult your owner's manual to locate the interior fuse box (usually under the dashboard) or under-hood fuse box.

Locate the Wiper Fuse: The diagram on the fuse box cover or in your manual will show which fuse controls the "Wiper" or "Wiper/Washer."

Inspect the Fuse: Pull the fuse out using the plastic fuse puller (often stored in the fuse box). Look through the plastic—if the thin metal wire inside is broken, the fuse is blown.

Replace It: Swap it for a new fuse with exactly the same amp rating (e.g., 10A, 15A).

Pro Tip: If the new fuse blows immediately when you turn the wipers on, you have a short circuit in the motor, and a mechanic will need to look at it.

Quick Fix #4: The "Unfreeze" Trick (Winter Only)
If you try to use your wipers on a freezing morning and they won't budge, they are likely frozen to the glass. Do not force them—forcing them will strip the gears or burn out the motor.

How to do it:

Turn on Defroster: Start your car and turn the front defroster to maximum heat.

Wait: Let the warm air melt the ice seal between the rubber blade and the glass.

Scrape: Use an ice scraper to gently break any remaining ice around the arms.

Test: Once the glass is clear and the blades move freely, test the wipers.

Last Resort: The "Manual Assist" Trick
Sometimes the wiper motor is strong enough to work, but the arms are stuck in a position where they can't overcome the initial friction.

Turn off the ignition.

Lift the wiper arms gently away from the glass.

Move them back and forth by hand a few times to loosen the gear mechanism.

Lower them back down and try the switch again.

When to Call a Professional
If none of these simple tricks work, the problem is likely more serious. You may be dealing with:

A burned-out wiper motor: No sound at all, or a faint click but no movement.

Broken linkage: You hear the motor running, but the arms don't move.

A faulty relay or switch: The electrical signal isn't reaching the motor.

Summary Checklist:

Spray WD-40 on the pivot points (fixes stuck linkage).

Check the nut at the base of the arm (fixes loose arms).

Replace the fuse (fixes electrical failure).

Defrost the ice (fixes winter freeze).

Try these steps in order. Often, a $5 can of WD-40 or a $2 fuse is all you need to get your wipers working again.
