GMC 19244660 Combination Switch

Operations for removal and installation of the components are divided in a sequential way starting from those parts which are located close to the upper part of the steering column. Start with the removal of the cable from the negative terminal of the battery, unless for the models with Delco Loe II audio systems the anti-theft system should be turned off. Align the front wheels towards the right direction, switch of the ignition off and take out the key. Third, pull the steering wheel off. For models from 1990 and later, set the airbag system off, then unbolt the airbag coil retaining snap-ring and the coil assembly should hang by the wiring harness. Depending on airbag coil reinstallation, center it with help of spring lock depressed while retaining the hub as it is told, and then release the spring lock. Release the horn contact bushing and spring, demold the plastic cover of the steering column, and detached the shaft lock if it is necessary to use a special U-shaped tool. Remove the canceling cam assembly and the upper bearing preload spring and, if no other part is going to be replaced, proceedings for assembly should be undertaken in reverse order while making sure that the turn signal switch is in the neutral position. For the turn signal switch it is necessary to remove the lever attaching screw, then unscrew the hazard warning knob and remove the three mounting screws. Remove the screw holding the turn signal switch and pull the switch with the attached wiring harness from the top of the steering column and disconnect the turn signal switch wiring connector. If no other components are to be remove then follow the instructions to install it and be sure that the wiring harness is covered. For ignition lock cylinder, put it in RUN, take out ignition key warning switch and cautiously unscrew the lock retaining screw with the magnetised screw driver. Slide the lock cylinder away and insert it into the right position for the keyway and lock it in place by pushing it in and tightening retaining screw. The ignition key warning switch can be freely integrated and isolated from the ignition lock. Should the ignition lock cylinder remain functioning, place the key into the Run position, and using stiff wire pull out the switch, make sure that the buzzer switch actuating button is pressed down before fitting in the new warning switch; Other remaining components can then be reassembled.
