The turn signal, headlight dimmer and the windshield wiper or washer control are sited together on the turn signal switch placed on the left side of the steering column. To test the switch, first, the switch should be detached, then, by utilizing an ohmmeter or self-powered test lamp in conjunction with the diagrams provided utilize the switch to determine if continuity exists between the switch terms in the various positions that have been identified; in case continuity does not exist as indicated, the switch should be replaced. For the models made between 1991 and 1994 years start with the removal of the steering wheel followed by the removal of the instrument panel trim under the wheel. If the model is equipped with the tilt steering wheel, then, pulling the upper extension shroud to the right and left with your hands and pressing buttons, located in the six and twelve positions, the shroud should be unbolted from the special plate. Next, take out the screws placed at the upper and lower shroud and after that the screws which joins the switch assembly to the steering column. Now, using a small screwdriver free the electrical connector from the switch and finally pull out the switch assembly. Installation is the process of reversing the removal exercise, only shifting the horn harness grommet to the correct place as well as inspecting the steering column as well as the switch. For the models of 1995 and subsequent years, it will be required to take away both the upper and the lower steering column covers, while the process of taking out the switch will presuppose the necessity of disconnecting the electrical connectors, and the separate removal of the two screws, which hold the switch in place and allow for taking it out without removing the steering wheel.
