CLB Questions
I just picked up a 2000 Coupe the other day and am looking into the Column Lock issue. I read This thread, so I do kinda know the story.
According to my VIS info
01044 was performed (Customer Satisfaction)
04006 was NOT performed (Safety Recall)
Some questions:
1.My car has nearly 100k miles on it, do I still need the CLB if the column lock hasn’t been a problem (according to the last owner) and it has the one recall done? Sounds like there could be conflicts if the recall is done and a CLB is used.
2.What is the difference between 01044 and 04006?
3.Can I tell if I have a CLB on my car without tearing the dash apart?
Thanks.

Do you hear the column lock motor run when you turn the key on or off?(should hear a little zzzzt sound if it does),and does your column lock?
If it does there's a potential problem waiting to happen.
If you don't hear the lock motor,and your column doesn't lock,and you don't get the "pull key,wait ten seconds",or"service column lock" warnings on the DIC,then the column lock has been disabled,and with 100k on it,I'd say you're probably good to go.
If I'm wrong,someone is going to chime in real quick to tell you just how wrong I am,--all I'm saying is if the column isn't locking,and no warnings come up on the DIC,Leaving it alone might be the best move, because apparently whatever was done to disable it is working fine.

Just tested and yes I do get the "zzzt" sound and the column locks, so I take it I don't have a CLB installed. Thanks a lot for the help on that.
Sounds like your suggesting if my column lock is actuating I might want to consider a CLB. I guess I'll order one tomorrow unless someone chimes in with a different opinion.

The CLB is the first thing I got for my Vette-I couldn't think of anywhere that would be a "good" spot for it to be immobilized..
And,the upside to doing it while your column lock is still functioning,is on the off chance that the CLB should ever fail,you can put it back the way it was and drive away.

Since the column locks you definitely do NOT have a CLB installed. Profile says car is a manual trans 2000. That makes a difference in what you need to look for when you attempt to install the CLB. There are different variations of the 01044 just as there are variations of the 04006. What was done to your car needs to be determined. You can get the GM VIS report and hopefully that will shed some lite on what was done in the 01044. Best bet is to LOOK and see for your self. The GM K Harness was installed in some variations of 01044 and the spliced purple wire relay in the passenger foot well was also done. If Ihad to guess your 2000 has the spliced purple wire in the passenger footwell and NOT the GM K Harness.
To determine if you have the spliced purple wire mod you need to remove the toe kick in the passenger footwell. Easy to do. Then, to the left of the fuse box and above the BCM (large silver box) look for a relay that has 5 wires going into the wiring base of the relay. There will be 1 white, 2 orange 1 green and 1 purple. The purple wire will be spliced into the wires that go to the BCM connectors. It will look like this:

If you have that spliced purple wire mod, then you MUST bypass the relay in order for a CLB to function properly. More on how to do the bypass below.
If you do NOT have the spliced purple wire mod then you MAY have the GM K Harness installed. If it is installed it in on the drivers side behind the knee bolster. The K Harness looks like this:
http://forums.corvetteforum.com/1567913186-post8.html
If it was installed it will be in series between the lock motor and the connector that goes off to the BCM. Easiest way to recognise the K Harness is by a female connector has ONLY 2 wires going into the back side. One is white and the other is purple. If you have the K Harness you need to disconnect BOTH ends of it. Then the CLB gets plugged into the female connector that is attached to the bottom of the dash. The male connector from the lock motor gets left disconnected. DO NOT PLUG THE CLB INTO THE FEMALE CONNECTOR THAT HAS ONLY TWO WIRES.
A few cars I have seen have had BOTH the K Harness and the spliced purple wire mod. The car should have had only one and not both. Either way you need to remove/disconnect what ever GM has done to the car in order for the CLB to function properly.
If you had the spliced purple wire mod, here is a link on how to bypass the relay:

One last link that may be helpful is how to pull down the drivers side knee bolster. The first part of the following link explains that with pictures:

One caution you need to be aware of if you do install a CLB. A CLB simply prevents the column from locking. If the variation of 01044 on your car reset the fuel shutoff to 2 mph (some did and others did not) then you CAN still experience the fuel shutoff if/when the battery goes low on you. You can determine if you have the fuel shutoff by disconnecting what ever is plugged into the female connector on the bottom of the dash (either the GM K Harness or the column lock motor) and then start and attempt to move the car. If the engine shuts off as soon as you let the clutch out then the fuel shutoff is set. Only way around the fuel shutoff is to find a tuner with either HP Tuners or EFI Live tuning software and have the shutoff speed reprogrammed to a high number. Many choose to live with the fuel shutoff set to 2mph. Personal choice. I have the speed of my fuel shutoff set to 255mph.
If you still have questions feel free to post them back here or PM me....

When you order from Corvettes of Houston, have the part delivered somewhere you can sign for the package. They won't leave it. They require a signature and it will be returned to them if you can't sign for it.
Then you get to do it all over again.
It is worth it so save yourself the trouble.

OK, I finally got my bypass. Looked today and I have the purple wire fix. I'm thinking I do not have the k harness, but will take a look when I get in there. So I think it's pretty straight forward with the links you provided 8VETTE7. Wish me luck.

Hi guys. I'm new here and have a 02 Z06 and I have checked the things listed above to see if I have a CLB. When I turn the key on I am sure I hear the quick "zzzzt" sound as mentioned but my steering wheel will turn with the key on or off without locking up. If a CLB is installed where do most people mount the little box at under the dash?
Thanks!
