When servicing the wiper motor linkage, the battery ground cable is typically disconnected to isolate the electrical system, and depending on the vehicle the wiper pivot arm is removed after the nut cap and nut are taken off so the arm can be withdrawn. Care is taken to avoid using clean-up solvents near the blades, and in some cases stickers on the wiper pattern area of the windshield are avoided because adhesives or contaminants can damage the blade elements. The cowl top vent panels are removed and the wiper motor electrical connector is disconnected, then the mounting arm and pivot shaft assembly is unbolted and withdrawn. Reinstallation is generally carried out by reversing the disassembly steps. Be aware that after the battery has been disconnected and reconnected the vehicle may display abnormal drive symptoms while its adaptive strategy is relearned, and depending on the system this relearning can require driving roughly 16 km (10 mi) or more.
