    Q:
    How to remove and install Ignition Switch on Cadillac ElDorado and Fleetwood? Posted by Customer
    A:
    When working on the Cadillac DeVille and Fleetwood models, you should disable the Supplemental Inflatable Restraint (SIR) system to prevent accidental airbag deployment or injuries. To do this, turn off the ignition switch as well as disconnecting the negative battery cable. Remove the specified SIR fuse from the fuse panel, and in some models eliminate lower left sound insulator. Next, detach the Connector Position Assurance (CPA) and disconnect the yellow 2-way connector at the base of the steering column. This will enable you to lower and support the steering column for better access. Remove the screw and washer that retain ignition switch and dimmer switch along with ground wire. Afterward, remove dimmer switch from rod as well as ignition switch mounting stud. Go ahead to take out ignition switch from its actuator on ignition switch, detaching any electrical connectors necessary. When installing ignition switch ensure it is in OFF-LOCK position secure by mounting stud. Re-enable SIR system by connecting yellow 2-way connector, installing SIR fuse, connect negative battery cable then check functioning of "INFLATABLE RESTRAINT" indicator light after completing installation. For early Eldorado and Seville models, follow similar steps to above mentioned ones when disabling SIR system. Take out SIR fuse No. 19 from fuse panel, left side sound insulator, and CPA including a 2-screw center trim plate followed by knee bolster held by five screws together with four screws attaching instrument panel steering column reinforcement plate to dash structure as well as a protective covering for wiring of an ignition switch plus retaining screws disconnected where necessary among others are parts remaining connected such that when installed in an OFF-LOCK position it will be secured with retaining screws only. Then reconnect turn signal harness connectors for both switches; also include any other harness connectors except for instrument panel harness connectors through which you could have attached these wires but that you did not attach to the wires when you installed the new instrument panel. Reinstall wiring protector and assemble components together. What to do in order to enable the SIR system? Connect the yellow 2-way connector, SIR fuse must be installed and then negative battery cable should be connected with the "INFLATABLE RESTRAINT" indicator light checked for proper functioning. Late Eldorado and Seville models are disabled by turning off the ignition switch and disconnecting the negative battery cable; remove specific SIR fuse, left side sound insulator, CPA as well as yellow 2-way connector at base of steering column. The knee bolster comes next along with an instrument panel steering column reinforcement plate, lower support bracket, upper column support bolts that can be removed after unscrewing them. Move down on that steering column and remove its wiring protector while retaining screw is provided for ignition switch; nut is also kept for this device that holds it firm till the installation is finished with connectors disconnected where necessary among other parts remaining connected such that when installed in an OFF-LOCK position it will be secured with retaining screws only. Next, reconnect turn signal harness connectors for both switches; also include any other harness connectors except for instrument panel harness connectors through which you could have attached these wires but that you did not attach to the wires when you installed the new instrument panel. Thereafter, install this wiring protector type onto steering column then ensure both upper and lower column support bolts are tightened thus raising a steering column using two supports available in order to align these supports near opening inside instrument panel once again before tightening them so as to complete a task on reassembling all of such remaining components whereby after connecting yellow 2-way connector, installing SIR fuse, connect negative battery cable then check functioning of "INFLATABLE RESTRAINT" indicator light.

    Q:
    How do you remove the ignition switch for the 1984 Buick Skylark? Posted by Customer
    A:
    Disconnect the two wiring leads, starting with the one farthest from the steering wheel. Remove the stud and screw securing the switch to the column, and lift off the switch, making sure to pull it up from the column due to the protruding ignition actuator rod.

    Q:
    How should you approach working with the steering column switches on the 1999 Chevrolet C1500? Posted by Customer
    A:
    On 1995 and later models, when working with the steering column switches, start by removing the steering wheel and the steering column cover. Remove the Torx-head bolt, unplug the electrical connector, and lift off the turn signal switch. Installation is the reverse of removal. If needed, center the airbag coil by removing it, turning it over, depressing the spring lock, rotating the hub as instructed, and releasing the spring lock. Finally, install the wave washer and the airbag coil, ensuring the lower wiring harness is taut to prevent damage when turning the steering wheel.
