On trying to solve the problem of the wiper motor, one begins with a check on the fuse block to find whether a fuse has blown. After that look at the wiper switch. Start the ignition and wiper switch and with the jumper wire touching the two terminals of the wiper motor, turn on the switch; if the motor moves, the ground connection should be worked on. If the wipers remain non operational, switch on the wipers and the check the voltage on the motor connection. If voltage is detected, pull the motor and check it separately with fused jumper wires off of the battery; if it runs, check the linkage for binding; if it does not run, replace the motor. If there is no voltage reading on the motor then the problem should be expected to be either in the switch or in the wiring. For replacement, one has to relieve the negative battery terminal, identify the positions and then remove the nuts and to remove the wiper arms. Subsequently, use thin arms to pull out the cowl cover and then use the fingers to pull out the electric connector of the wiper motor and then uninstall the four mounting bolts. Apply a wrench to tighten the motor drive crank, unscrews the crank nut, take out the crank then lift the motor. In installation, the procedures are done in the reverse order of removal.

Start by removing the ignition key from the key lock cylinder.

The first step is to pry off the protective caps over the wiper arm nuts to access each retaining nut, then remove the nuts that attach the wiper arms to their splined shafts.

The next step is to remove the cowl cover, release the lock on the wiper module electrical connector, and disconnect it from the wiper motor by pushing the lock up and depressing the release tab.
