2016 Chevrolet Equinox Windshield Wiper Motor Replacement in Ann Arbor, MI

The customer reported attempting to use the windshield wipers on this 2016 Chevrolet Equinox while the wiper blades were frozen to the windshield. They defrosted the windshield afterward, but the wipers will not work now.

Diagnosis

Our Chevrolet repair technician confirmed the customer's concern that the front windshield wiper would not work. The first thing they checked was the wiper motor fuse, and they found it had failed. They replaced the fuse, but the wiper motor would not function.

Next, they removed the wiper cowl below the windshield to gain access to and inspect the wiper motor and wiper linkage. No obvious problem or damage was observed.

Next, the technician tested the wiper motor wiring for electrical power, ground, and the function of the wiper motor relay but found no obvious faults. With the wipers switched on, the wiper motor slowly started to turn when the windshield washer setting was selected, but the motor began making loud growling and grinding noises as the motor speed increased.
The technician suspected the gears inside the wiper motor were damaged when the motor was switched on with the wiper blades frozen to the windshield. The gears are plastic and will often break in cold temperatures when the motor attempts to free the wiper blades from the ice.

The only repair solution is replacing the wiper motor assembly.

The customer was contacted, the problem was explained, and an estimate for wiper motor replacement was provided. The customer approved the repair.

Repair

The old wiper motor's electrical wiring was disconnected, and the motor was unbolted and disconnected from the wiper linkage. A re-manufactured wiper motor was installed, the electrical harness connected, the cowl cover panel replaced, and new wiper blades installed. The wiper motor operation was checked, the windshield was cleaned, and the new wiper blades provided the driver with a clear, streak-free view.

Tips

Always make sure your vehicle's wiper blades are free of snow and ice before starting the vehicle and switching on the wipers.

A spray bottle containing windshield washer antifreeze can be sprayed on frozen wiper blades to melt any ice and ensure the wipers can move without overloading and damaging the motor or wiper linkage.

Before turning off your vehicle, make sure the wipers are switched off and allowed to return to their parked position. If the vehicle is shut off when the wipers are actively moving and not in the parked position, the wiper blades can freeze to the windshield when the vehicle cools. When the cold vehicle is started, the wiper motor will struggle to move the frozen wiper blades, and the motor can tear the wiper blades, bend the wiper linkage, or, in the worst case, overload and damage the wiper motor.

FAQ

How Often Should Windshield Wiper blades be replaced?

Windshield Wiper blades should be replaced every year. It is best to replace wiper blades at the end of summer before winter. The hot sun of summer damages the rubber wiper blade causing them to harden and leave streaks on the windshield.

Why do wiper motors go bad?

There are two main reasons wiper motors fail. First, is simply age and normal wear. Wiper motors will usually last about 10 years. Less if your location gets lots of rain and snow. Longer if the wipers are rarely used.

The second reason wiper motors fail is when the wiper blades freeze to the windshield and place excess load on the wiper motor. The motor will overheat or the plastic gears in the motor assembly will break from the heavy load of freeing the frozen wiper blades or pushing through heavy snow.

Can wiper motors be repaired?

Usually, by the time a wiper motor fails, it is worn out and not worth repairing. Finding repair parts can also be difficult.

It is better value to replace a failed wiper motor with a new or remanufactured unit. It is more economical to purchase a factory-remanufactured wiper motor assembly versus a new unit.
