Pontiac Grand Prix Windshield Wiper/Washer System Inspection at your home or office.

Common reasons for this to happen:

Windshield Wiper Issues

• Worn wiper blades: Wiper blades need to be replaced on a regular basis. Worn wiper blades will not clean the windshield. Smearing or streaking are common symptoms of worn blades. If the blades chatter this can also indicate dirty or worn blades. Torn or cracking blades need to be replaced.

• Bent or loose wiper arms: Wiper arms can become bent, usually due to vandalism. If the wiper blades are not cleaning the windshield but still appear to be in good shape loose or bent wiper arms could be the problem.

• Malfunctioning wiper arm linkage: The linkage between the wiper motor and the blades can become damaged. The most common symptom of a broken linkage is one wiper arm not working.

• Blown fuse: A blown fuse will cut off the electric current to the wiper motor. If both blades fail to function when turned on, a blown fuse is usually the starting point for a diagnosis.

• Bad wiper motor: If the blades fail to operate at all, are operating slowly, only operate on one speed or do not stop in the correct position a bad or malfunctioning wiper motor could be the culprit. The motor will need to be repaired or replaced.

• Defective wiper switch: If the wipers do not turn on when the switch is flipped, keep running after being switched off or it is impossible to select the proper speed settings the switch may be defective and will have to be replaced.

Windshield Washer Issues

• No washer fluid: One of the most common reasons windshield washers fail to work is because the fluid reservoir is empty.

• Blown fuse: Fuses provide overcurrent protection to all of the vehicle’s electrical units and this includes the windshield washer system. If a fuse blows, the electrical current to the washer pump will be cut off and the washer system will not work.

• Bad windshield washer switch: The switch that turns on the windshield washer can malfunction and fail to send a signal to the pump. If this happens the pump will not work.

• Broken washer pump: The electric pump that sends the fluid from the reservoir to the nozzles can malfunction or break.

• Leaky washer tubes or bottle: The washer reservoir or the tubing that moves the fluid to the nozzles can crack or leak. This can lead to lost fluid on route to the nozzles, which can result in a weak spray or no spray at all.

• Clogged washer tubes or nozzles: The tubing or the nozzles themselves can become clogged with debris. The nozzles, which are quite small can easily get clogged by dirt, leaves or other debris.

• Frozen washer fluid: In extremely cold weather it is possible for washer fluid to freeze. If the fluid is frozen it should thaw as the car warms up.
