How to Tell If Your Wipers Need Replacing

Windscreen wipers are one of those parts of the car that are easy to forget about until the weather turns.

During dry summer months, they might barely be used. Then suddenly, as rain, spray, darker mornings and early evenings return, you rely on them every day.

If your wipers are worn, damaged or not clearing the screen properly, it can make driving much harder than it needs to be. Poor visibility is frustrating in daylight, but it becomes much more serious when driving in the dark, in heavy rain or on busy roads around Shaftesbury, Blandford and the wider Dorset area.

At DCM Autocentres, we always recommend checking your wipers before autumn and winter weather properly sets in.

Here are the signs to look out for.

Your wipers are leaving streaks

One of the clearest signs that your wipers need replacing is streaking.

If the blades are leaving lines across the windscreen, they are no longer making clean, even contact with the glass. This can happen when the rubber becomes worn, hardened or slightly split.

Streaks might not seem like a major problem at first, but they can quickly become distracting when headlights, streetlights or low winter sun reflect off the glass.

If your screen still looks smeared after using the wipers, it may be time for a new set.

They are smearing water instead of clearing it

Good wipers should clear water away quickly and leave the screen easy to see through.

If they are dragging water across the glass, smearing dirt or making the screen look cloudy, the blades may be worn. Sometimes this can also be caused by grease, road grime or old screenwash residue on the windscreen.

It is worth cleaning the windscreen and blades first. If the problem continues, the wipers are probably not doing their job properly anymore.

They squeak or judder across the screen

Wipers should move smoothly across the glass.

If they squeak, judder or skip, it usually means the rubber is not sitting correctly against the windscreen. This can happen when the rubber has hardened, the blade has lost flexibility or the wiper arm is not applying even pressure.

Juddering wipers can leave large areas of the screen uncleared, which is especially dangerous during heavy rain or motorway driving.

The rubber looks cracked, split or loose

A quick visual check can tell you a lot.

Lift the wiper blade gently away from the screen and inspect the rubber edge. Look for cracks, splits, missing sections, rough edges or rubber that is starting to peel away from the blade.

Even a small split can stop the blade from clearing properly.

If the rubber looks brittle or damaged, replacement is usually the safest option.

They struggle in heavy rain

Sometimes wipers seem fine during light drizzle but struggle when the rain gets heavier.

This is usually when worn blades become more obvious. They might miss sections of the windscreen, leave water behind or fail to clear spray from other vehicles quickly enough.

With darker mornings and evenings, wet roads and extra glare from headlights, your wipers need to be able to cope properly.

If they only work “well enough” in light rain, they may not be ready for tougher weather.

Your visibility is worse at night

Worn wipers can make night driving much more uncomfortable.

When water, dirt or streaks are left on the windscreen, headlights from oncoming traffic can scatter across the glass and make it harder to see clearly.

This can be especially noticeable on unlit roads, country lanes and busy commuter routes.

If driving at night feels more difficult because the screen never seems clear, your wipers are worth checking.

They are making your screenwash less effective

Screenwash is important, but it cannot do the job properly if the wipers are worn.

You might find yourself using more screenwash than usual because the blades are not clearing dirt, salt or road spray properly. In autumn and winter, this becomes even more noticeable as roads get wetter and dirtier.

Make sure your screenwash is topped up and suitable for colder weather, but do not rely on screenwash alone if the blades are already damaged.

How often should wipers be replaced?

There is no exact rule for every car, because wipers wear at different speeds depending on weather, use and where the vehicle is parked.

Cars parked outside in strong sun, frost or heavy rain may wear blades faster than cars kept under cover. Wipers can also wear more quickly if they are used on a dry or dirty windscreen.

As a general guide, it is worth checking them regularly and replacing them as soon as they stop clearing properly.

It is a small, relatively simple job, but it can make a big difference to everyday driving safety.

Can worn wipers affect your MOT?

Yes, they can.

If your wipers do not clear the windscreen properly and affect the driver’s view of the road, it can cause an MOT issue.

That is why it is worth checking them before your test, especially if they are already leaving streaks, smears or uncleared patches.

If your MOT is due soon, our MOT testing team can help make sure key safety items are checked properly.

Do not forget the rear wiper

Rear wipers are easy to overlook, but they still matter.

If your car has a rear wiper, check that it clears properly too. A dirty or smeared rear screen can make reversing, parking and checking traffic behind you more difficult, particularly in wet or dark conditions.

Estate cars, hatchbacks and SUVs often pick up a lot of road spray at the back, so the rear wiper can be used more than you realise.

A simple seasonal check can help

Wipers are only one part of getting your car ready for wetter and darker driving conditions.

It is also worth checking your lights, tyres, brakes, battery and screenwash before autumn and winter fully set in. If your car is due a wider check, regular car servicing can help spot small issues before they become bigger problems.

For wet roads, your tyres matter just as much as visibility. If you are unsure about tread depth or tyre condition, our tyre fitting team can check them for you.
