Cadillac Windshield Wiper Troubleshooting

Do you want to troubleshoot Cadillac windshield wiper problems? Or, do you want to know how to test the windshield wipers at the module? Problems with the windshield wipers can be few and far between but if they do arise it can be problematic and frustrating. Most of these issues have simple troubleshooting and repair steps which can be performed by the car owner if they have the right information. When you are looking for solutions, opinions or insights, the assistance of Cadillac Experts online can be highly useful.

Read below where Experts have answered a few questions about windshield wipers for Cadillac car owners.

What can be done if the windshield wipers on a 2011 Cadillac Escalade work at low speeds and seize after a few minutes?

The problem here could be a poor power or ground feed to the wiper motor or based on the symptoms, it could also be a failed windshield motor. To confirm this, one needs to test the power and ground feeds to the motor. This can be best carried through a load test, using a headlamp or fog lamp bulb and a couple of jumper wires. When connected to power and ground at the motor, the bulb should light up brightly, similar to how it would be if it were connected to the battery. If it does light up, it confirms that the problem lies with the motor.

How to test the windshield wipers at the module on a 2003 Cadillac CTS?

The windshield wipers should be tested when they are acting up or not working properly. The test to be carried out should be on the wires at the module using a multi-meter and the instructions are as follows:

  1. The windshield wiper motor’s electrical connector should be disconnected.
  2. The key in the ignition should be turned ‘On.’
  3. The windshield wiper switch should be turned ‘Off.’
  4. The multi-meter should show zero volts on the gray pin B, dark blue pin C and purple pin G.
  5. In case voltage is present on any of the wires, most likely the problem is with the windshield wiper switch or there is a short circuit at that wire.
  6. If the voltage is zero at each wire and the wipers remain on, the wiper module which is a part of the windshield wiper motor assembly, should be replaced.

What causes the windshield wipers on a 2000 Cadillac CTS to turn on randomly?

It is either the windshield wiper switch or wiper motor/module that has failed here. The more common cause of the two is usually the windshield wiper motor or module. To check this, the 10 amp WPR SW fuse in the fuse box below the hood should be removed. If doing this stops the windshield wipers from turning on, it implies that the switch has failed. If they continue to turn on after the fuse removal, the windshield wiper motor or module has failed. 

What causes the Cadillac windshield wipers to work continuously?

Case Details: The wiper fluid started to flow when the turn signal was engaged.

Windshield wiper motor failure is common, where the problem is either that the wipers operate continually, cycle independently or randomly. The other issue could be with the circuit board on the windshield wiper motor. To test this part, the cowl will need to be removed to gain access to the wiper motor connector. Apart from this, the multi-function switch on the steering column could be malfunctioning because of the washer fluid malfunction when the turn signal was used. 

Why do windshield washers run when the wipers on a 2006 Cadillac CTS are turned on?

The windshield wiper module which is attached to the wiper motor is most probably faulty. This module is responsible for controlling the washer function. Sometimes, the circuit boards can get wet too and cause the wipers to function abnormally. To deal with this, the wiper motors need to be replaced but prior to doing so, one needs to troubleshoot and diagnose the problem further.

After replacing the ignition switch on a 2000 Cadillac Escalade, which part is making the windshield wipers work intermittently?

Most likely, the problem is with the body control module or the BCM. The BCM is responsible for controlling the accessory power circuits for the windows and the windshield wipers. To overcome this problem, the BCM needs to be replaced and it can be found below the center console.

Windshield wiper problems can be minor and temporary or can be constant and concerned with other related parts. Troubleshooting these issues can be fairly simple and straightforward if you have the information and key steps involved. As seen above, this is possible with help from Experts online. In order to attempt windshield wiper troubleshooting on your Cadillac, contact mechanical Experts online for information, opinions, and expertise. Their simple tips and answers may not be available in manuals and shops, saving you time, money and effort.
