To replace a set of wiper blades, a technician must first identify the type of mounting hardware that is needed for your vehicle. Some replacement blades come with universal connectors that can be adapted for most wiper systems, but that is not always the case. The specific length of the blade must also be taken into consideration. Most vehicles use one length of blade on the driver’s side and another on the passenger side.
Once the proper replacement blades have been identified, the technician will raise the wiper arms (this sometimes requires that your hood be raised as well) and detach the old wiper blade from each arm. The new blade is installed carefully onto the arm and set back into place. The technician will then test the system to make sure the blades have been installed properly. Improper installation can allow the wiper blades to come free while driving, scratch or break the windshield, or damage the wiper blade attachment hardware.
