Electric steering wheel adjustment not working - Reach/Rake

The ignition lock cylinder in your 2002 Chevrolet Tahoe has to be replaced if the key will insert but not turn the ignition. For older vehicles, this is a relatively common issue that is typically easy to fix. To access the ignition lock cylinder, you must first remove the steering wheel. The cylinder can be removed and the outdated one with a new one once the steering wheel has been relocated out of the way.

You will have to remove the lock and then make sure the steering wheel lock is permanently disengaged before putting the column back together without the lock cylinder. While you are there, you can also remove the ignition switch and reconnect it external to the column so you can use it. Here is the procedure: Except 240 Series

some of these electric interlocks require the brake pedal stepped on for releasing..have you tried that? along with shifting fully into park a few times?

If its a key with a electric code some time you have to have a new code key made any lock smith can do it there not cheep. I just paid $175 for mine to be done now it works great

Hello, Dan. First, disconnect the negative (-)/ground on the battery Dan are you mechanically inclined. If not then don't attempted this job.

You will need to remove all the plastic covers on the steering column. Remove the horn ring.--two screws under the steering wheel. Remove the horn ring and disconnect the horn plug. Remove the steering wheel nut. Use a steering wheel puller to remove the steering wheel.

Remove the turn signal switch that fit around the upper part of the steering column. Then remove the some of the parts that are associated with the steering wheel and/or column.

Now, look at the ignition switch flange, it a big chunk of aluminum. Now look for a large aluminum dowel pin 5/8" in diameter that is driven into the chuck of aluminum but it is parallel to the steering column.

This aluminum dowel pin will have to be drill out before you can get ignition housing off, If there is adjustable steering column lever, remove this also.

Now, once the dowel pin has been removed, looking for a **** in the ignition housing. Take chisel and insert into this ****, drive the chisel into the **** until the ignition housing is loose to be remove by sliding it up over the steering column.

If you buy a new ignition switch, on purchase the switch with keys. Don't buy the hole new ignition housing.. If you do it will get expensive.

In the ignition (old) housing drive out the ignition switch pins that keeps the ignition switch in the housing. Install the new ignition switch re-insert the ignition switch hold pins.

I am fairly sure that Carquest/ NAPA some other larger auto parts will have ignition housing bolt. If they try to sell you a replacement aluminum dowel pin don't buy it. It is almost impossible to install the aluminum dowel pin without the proper tools, so use a bolt to squeeze ignition housing together.

Before putting everything back together. Now, check the new ignition switch to make sure it works. I wish you lot of luck. GB...stewbison

dont think you can on certain models ,only the more expensive ones ,try asking at the dealer if it does have a adjustable height control

Ignition switch located half way down steering column.
Ignition tumbler (Where you insert the key) Need to remove steering wheel, if tilt steering need remove c clip, then there is a hex bolt securing the tumbler.
Ignition switch is a bit more involved. hope this helps, James Booth

u need to change the ac/heater control panel.

This also happens when the battery is dead. If you can at least wiggle the steering wheel about 20° in either direction then the steering lock isn't the problem. (Although if you wiggle it too much it might be!)
