However, this problem could also be caused by a blown fuse, so you should start there. If the fuse has burned out, there could be a larger electrical problem occurring. If left unchecked, other components could start going bad too.
In most vehicles, this position is at the bottom of the windshield, where the wipers are essentially locked in place. While a replacement might be necessary, you may also be able to reset the wiper motor, which is a cheaper alternative. If you are experiencing any of the other problems listed above, you want to listen to the motor closely. You might hear a slight humming sound. This problem could also be caused by a bad wiper relay.
The windshield wiper motors are responsible for supplying power to the blades. When the motor works as it should, the blades move in a systematic, smooth motion. The motor works continuously when turned on to move the wipers back and forth across the windshield.
However, there are linkages and connections within the motor that can go bad over time. If any small component within the motor fails, it can lead to performance issues. It is mounted between the driving compartment and the car engine. Before you replace the windshield wiper motor, you should look at other lower-cost components that could cause your problem. For example, a blown fuse can cause the wipers to stop working and this only costs a few dollars to replace.
If the windshield wiper motor does need replacement, consider doing it yourself since it is such a simple job. Forgotten Password? How to Replace a Windshield Wiper Motor? Sep 26, We have made a very simple, step-by-step guide on how to replace your windshield wiper motor.

In that case you'll see voltage everywhere, even when the wipers are turned off Back to the schematic. As a last-resort diagnostic, jumper 12 volts directly from the battery to the appropriate pin on the motor's power connector.
If there's still no sign of life, it's time for a new motor. Before you unbolt the old motor, detach the transmission linkage, which may have nice, plastic ball-and-socket joints, simple pins with nylon bushings and E-rings, or some other arcane method of carrying the motion across the car to both wiper arms.
Reassembly should be straightforward. Lubricate all moving parts, using silicone grease on rubber pieces. Avoid using petroleum-based grease on rubber parts—it will deteriorate them. Some wiper arms have a friction fit to the wiper post. To position the arms correctly, briefly cycle the power to the wipers to park them. Now attach the arms in their correct at-rest position. Other wipers have splines that mate in only one position, so if the arms don't rest properly when parked, you'll need to adjust the linkage elsewhere, probably at the middle pivots.
Generally, the motor assembly is one of those things that have no user-serviceable parts inside and is inexpensive enough to make attempted repair pointless. If you have trouble finding a part for an oddball or collectible car, it may be worthwhile to open it up and poke around.
