It is likely a windscreen wiper motor will need to be replaced once or more during a vehicle lifetime depending on conditions. As the windscreen wiper is a vital piece of the vehicle's safety equipment and a legal requirement (for the front screen) then as soon as any issue arises. Do not be tempted to chance driving with a faulty windscreen wiper component, even if it is a dry sunny day, as conditions can change and other influences such as the car in front going through a puddle, can cause you a problem.

Obviously there is little you can do about wear and tear over the years, even with the following advice.

• Don’t switch on the wiper system when the blades are frozen to the windscreen. This causes undue stress on the motor and can lead to it burning out
• Similarly if the the vehicle hasn’t been used for a while, lifting off the wiper blades from the screen will unstick them and cause less stress on the motor when you first use it
• Always switch off the windscreen wipers before switching the engine off and leaving the car. This will ensure that they do not come on automatically the next time you start the engine (preventing the above scenarios) but also allows the wiper arms to be “parked” and not left at an unusual angle with which to start from. Again, this reduces the stress on the motor.
• Regular basic maintenance, such as lubricating the wiper motor linkage and replacing worn wiper blades all help with longevity of the motor.

Usually the windscreen wiper will completely stop working, in other words it will not work on any speed. If you switch the wipers to the on position and cannot hear any sound from the area close to the screen, it's pretty much going to be a fault with the motor or at least the fuse that covers it.

Some makes, such as Peugeot/Citroen have common faults with the column switches as well, which can have the same outcome, but the mechanic will be able to tell fairly quickly if this is the case.

Another indication of a failing windscreen wiper motor is then the wipers themselves either move jerkily or slowly across the screen.

It is not uncommon for a motor to be replaced once or more during a vehicle lifetime depending on conditions. As the motor is frequently used, wear and tear will eventually cause it to malfunction, the same as any other electric motor.

At some point a windscreen wiper switch can fail. If the wipers do not move or a washer does not work it is not necessarily the wiper switch that is faulty. It can be that the system has blown a fuse or electrical connectors have corroded or have come loose.

Equally, it might be that the motor powering the wipers or the washer fluid pump has failed. At an inspection the mechanic will establish, step by step, what the exact fault in the electrical system is before replacing any parts.

Cost of a windscreen wiper switch replacement depends on your location, car and what parts your car's manufacturer recommends using for the replacement. Find out what you could save by having your windscreen wiper switch replaced by ClickMechanic by selecting your car at the top of this page!
