Anyone have the telescopic steering just stop working. Haven't been able to locate a fuse/breaker???:smack: :smack: 2001 Vette

Dumb question but did you check your manual for the fuse? It has stopped completely?

Try pulling the switch toward you five or six times in quick succession. This will reset it as long as it isn't another problem. Nine times out of ten this will work. :thumbsup:

:iagree: The telescopic steering and seat vertical movement use soft stops that sometimes set if they have not been moved in a long time need reset.

I've had a similar problem in mine though it hasn't stopped altogether. One day I noticed that it just wasn't telescoping as far as it should (I like mine telescoped out all the way and my seat back all the way). I kept pulling the switch while pulling on the steering wheel and it suddenly extended further. Not soon after that though it stopped extending past a certain point permanently and ever since won't go any further. It sticks even before that point, but pulling the switch repeatedly gets it to extend further, just not as far as it used to (by about 2 or 3 inches short).

Asked the dealer and they said I need a new actuator I believe. Does this sound right? Doesn't quite make sense to me because the switch still works, but it simply will NOT extend nearly as far as it used to, as if it's running into something that's stopping it. Other than that the switch works just fine. Any gearheads intimately familiar with this assembly agree that that will resolve the problem? If not, what needs to be done?

Seems this started not long after I took the car in under the recall for steering column lock that was malfunctioning fairly often several years ago (2000 Vette btw). My steering wheel also started squeaking sometimes while turning, mostly only noticeable when making tight turns at very low speed such as in a parking lot, and it doesn't do it all the time (ambient temperature might play a role). The squeaking really bugs me, it's embarassing, but the dealer didn't sound too confident about fixing the problem when I pointed it out so I didn't have them touch it yet. Would like to get these problems resolved but don't want to pay for something I don't need and I don't want them messing things up even further when they open up the steering column :ack2:.

That sounds like a classic case of the soft stops needing re-set... :willy_nilly:

Are you pulling and releasing the button numerous times or keeping it pulled? As LV 2 XLR8 stated, the trick is to pull and release multiple times. If I recall correctly my steering took 6 cycles while the seat took more...

Pulling and releasing a bunch of times, and after several times it usually moves a little more, but it always stops well short of where it used to. I saw a post about this somewhere that said to reset them you had to push it toward the dash and release 8 times then hold for 5 seconds, then pull it toward you and release 8 times then hold for 5 seconds. Not sure if that's 8 then 1 more for the hold, or 8 and hold on the 8th... Was going to try it today and I forgot, might try it later.

When I get a moment of peace. I'll check my service DVD for you and get a straight answer...

Thanks, would appreciate it. Would LOVE to have my steering column extend all the way again :drool5:.

OK Firsf off have you checked for any codes in the SCM? If you have a B2860 in there, here:

Circuit Description

Tilt/Telescoping Steering Column Operation

The telescoping steering column in/out switch is an input to the seat control module. The telescoping drive motor is an output function of the seat control module. The telescoping actuator assembly is cable driven by the telescoping drive motor.
Steering column memory settings are stored in the seat control module. The steering column position sensor is an internal part of the telescoping actuator assembly, and is an input to the seat control module. The seat control module uses the position sensor input when storing and recalling memory settings.
Memory steering column, and the easy enter/exit operations are performed by the seat control module. However the left door control module controls when memory settings are stored and recalled, by use of the serial data link. The body control module controls when the easy enter/exit operation occurs, by use of the serial data link.
The body control module stores the RPO code configuration which signals to the seat control module whether or not the telescoping steering column option is active. This RPO code configuration must be correct, and received by the seat control module, or power seat, and telescoping steering column operation will be inoperative or incorrect.

The memory seat and telescoping steering column position settings are stored in the LH Seat Control Module (SCM). The SCM measures and stores the steering column position by using a position sensor, which is an internal part of the telescoping actuator. The SCM provides the position sensor with a 5 volt power supply (circuit 2113), and ground (circuit 2152). The SCM monitors the position sensor signal voltage (circuit 2153), which ranges from 0.1-4.78 volts depending on the steering column position. The steering colunm position sensor becomes active only when the SCM detects a steering column in/out switch input.

The steering column position sensor signal, to the SCM (circuit 2153), is less than 0.1 volt or greater than 4.78 volts for 2 seconds or more.
<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=573818&evc=sm&pubid=180&cellId=59034&mspsdsubkey=931#ss3-573818">Action Taken When the DTC Sets

A history DTC B2860 is stored in the SCM memory.
This DTC can only be set as a history code even if the malfunction is current.
No driver warning message will be displayed for this DTC.
The memory operation/function of the faulted position sensor is disabled.<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=573818&evc=sm&pubid=180&cellId=59034&mspsdsubkey=931#ss4-573818">Conditions for Clearing the DTC

The steering column position sensor input, to the SCM (circuit 2153), is within 0.1 volt to 4.78 volts for 2 seconds or more.
Using a scan tool.<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=573818&evc=sm&pubid=180&cellId=59034&mspsdsubkey=931#ss5-573818">Diagnostic Aids

If the DTC does not reset after the code is cleared the problem may be intermittent. Perform the tests shown while moving related wiring and connectors. This can often cause the malfunction to occur. Refer to Testing for Intermittent and Poor Connections (http://127.0.0.1:9001/servlets/CellHandler?CellId=62112&RefDoc=573818&evc=sm) in Wiring Systems.
The following conditions may also cause an intermittent malfunction:
There is an intermittent open, short to ground, or short to voltage in circuits 2113, 2152 or 2153.
The steering column position sensor is open or shorted internally.
If the SCM is unable to determine the correct steering column position, manual operation of the telescoping steering column will be functional, but the SCM will be unable to recall the correct memory settings.
Using a scan tool, select SCM data display and monitor the telescoping steering column in/out position data. Operate the steering column in both directions while monitoring the position sensor data. The voltage should range from 0.1 volt to 4.78 volts depending on the steering column position.<A href="http://127.0.0.1:9001/servlets/BlobShtml?ShtmlFile=573818&evc=sm&pubid=180&cellId=59034&mspsdsubkey=931#ss1-573831">Test Description

The numbers below refer to the step numbers on the diagnostic table:

<LI value=2>This test checks if a DTC B2860 stored in the SCM memory.
<A name=TD03><LI value=3>This test checks the telescoping steering column position sensor voltage using a scan tool. Normal position sensor voltage range is between 0.1-4.78 volts.
<A name=TD04><LI value=4>This test checks if the SCM is sending the correct supply voltage to the position sensor. The supply voltage measured must be between 4.0-5.5 volts.
<A name=TD05><LI value=5>This test checks for an open or short to voltage in CKT 782 or in the SCM internal ground circuit.
<A name=TD06>
This test checks the output voltage level at the position sensor signal circuit. The signal voltage measured must be between 3.5-5.5 volts.

The manual says to activate the switch in BOTH directions six times to reset the soft stops!

Had the same problem that i fixed this past weekend. Found an orange color wire separated from a connector that is right under the left rail of the driver seat. this wire is for the steering column actuator and goes to the seat control module.

Not meaning to hijack the thread, but I tried that on mine. No results at all. Won't move either way. Also jerked on the wheel - didn't help.

Did that. Nothing.
