For Sportage drivers who have slow windshield wipers, first make sure both the battery and motor are okay by fully charging the battery; if all parts work properly, take off the wiper motor and try moving the wiper arms manually to find if the linkage parts stick or pivot joints need oiling or mending before putting back the motor. If your wipers run too slowly after testing wires and ground connections, get a new wiper motor. If your wipers aren't working, start by checking the fuse; if it's good, attach a wire link between the wiper motor's ground connection and ground. Recheck to see if wipers work this way. Fix the ground connection if the motor runs; test for voltage at the motor with the wiper switch set to HI. Take out the motor and wire it to your car battery with fused jumpers. Check if the linkage moves smoothly while looking at voltage at the connection. If it doesn't work, replace it. When no power reaches the motor, look for voltage at the wiper control relays; if found, test the switch; if the switch is good, the wiper control relay may need replacement. When the wiper control isn't working right, check whether the electrical wiring between the switch and control module remains connected. When your wipers don't park, check if there's power flowing to the park feed wire on the wiper motor connector while alight and switch off. If there's no power, examine for an open circuit along the wiring path between the wiper motor and fuse panel. Before you can access the motor you need to remove the trim caps at both wiper arm ends, loosen both wipers, record the nuts' locations, and then take off the wiper arms. Take off the cowl cover clips and weather stripping, disconnect the wiper motor electrical connector and wiper de-icer cord from their units. Take off the motor/linkage assembly's bolts, pull it out, and put it safely on top of a clean working table. Take off the nut that holds the motor and linkage arm together, remove the arm, then carefully take off the motor's crank arm. Take off the motor mounting bolts to let the motor move away from the linkage piece, and put it back the other way around when installing. Make sure to match the post-installation wiper arm positions with your earlier marks. Make a mark on where the wiper arm hits your glass. After that, take off the cap, the nut, and the arm itself. Take out nut holding the rear hatch handle in place, detach the handle, pull back the rear tailgate window, and set aside the trim that covers the wiper motor. Unplug the power connection from the motor, loosen and remove three mounting bolts, and take out the rear wiper unit, but re-installation should be done in the reverse order, keeping the wiper arms properly aligned.
