# 1 – Wipers Are Out of Rhythm

There are times when the wipers seem not to work in harmony with each other. They can either hit a windshield molding or do not park low enough. Both these situations can be a sign that there are bent parts of the windshield wiper. The problem can actually be linked to a fault in the wiper transmission linkage although often it can be traced back to the wiper arms. In order to solve this problem, you have to make sure that the transmission linkage will be checked. As the driver, you must also clear the windshield from built-up snow. Turn the wipers on whenever the need arises and do not wait until dirt, dust, grime, and other weather elements accumulate on the windshield surface.

#2 – Wipers that Slow Down

There may be times that your wiper seems to work sluggishly than usual. In fact, even if you change the wiper mode, the manner with which the wipers move remain the same. This can be attributed to a fault in the wiper motor. The motor may be corroded or have shut off the last time you used the wiper. With that, it will fail to detect the setting you want to make use of.

In such a case, you need to figure out the problem by disconnecting the wiper linkage from that of the wiper. Turn on the wiper and once the motor runs properly then the problem can be actually attributed to the wiper transmission.

#3 – Frozen Wiper Blades

Wipers that are not moving at all can be a sign that you have forcefully directed the windshield to carry heavy loads. These systems were not designed to handle such tough jobs. Turning on the wipers during this instance will damage the wiper transmission linkage as well as all other parts that are attached to it. Ensure that you do not make the wiper system move heavy loads of leaves, dirt, snow, and rainwater or else it will keep on being problematic.

#4 – Wiper Does Not Run At a Particular Speed

This is another electrical problem in the wiper motor. Check the wiper fuse and see if wipers are not really working. There may be a separate wiper fuse for your vehicle. In this case, you need to get your car service manual and locate wiper problems. A diagnostic chart may be found in the manual. You can follow the chart and solve the problem accordingly.

There are times when you may need to replace the motor and all other faulty parts to make your windshield wiper work as smooth as before. Make sure you buy only genuine OEM Porsche parts.
