Should your horn, cruise control or airbag stop working the problem is most likely a failure of the "Spiral Cable Clock Spring". This $800 part resides under the steering wheel. A Lex Dealer quoted $1300.00 to replace it..Almost all modern cars have a clock spring, they cost $30-$60 dollars in most cases and are fairly easy to replace. Unfortunately, this is not true with the CT200h model Lexus..It requires a unique part and is fairly tricky to replace..You-Tube videos give you a rough idea how to do it but again the CT200h has a unique method of securing the horn / airbag to the steering wheel. There are no Torx head screws to loosen. instead there are 3 spring clips that secure the airbag to the steering wheel. These clips are almost impossible to see through the access covers in the steering column trim pieces. With a bright light and careful, close examination, you will find the tails of the spring clips exposed..Two on the left side and one on the right side. By using a long, thin screwdriver, push on the wire tail while you gently lift the airbag up from the wheel..You will feel the airbag pop free as you push on the clip tails one at a time. Once you find the first release clip, the other two are easier to find..The airbag will now lift free from the wheel. There are two wire connectors with tricky locking clips (lift them up) to disconnect the wires. The 'bag can now be set aside. To remove the wheel, follow the You-Tube Video. If it won't pop off (leave the nut on a few turns so it doesn't pull all the way off and damage the wires). If it won't come lose, borrow a steering wheel puller from Autozone. There are 3 wire connectors that must be disconnected first. Then carefully lift the wheel off and set it aside. Then two screws (as per video) and remove the column trim covers. The clock spring has several connectors which must be carefully removed. They all have locking clips that must be released to disconnect them. This clock spring has no screws holding it in place. There are three plastic clips that hold it in position. Release the clips and lift off the Spiral Cable Clock Spring Assembly.. Notes... Lexus used two or three different clock springs over the years..Be sure the part you purchase is correct for your vehicle by matching it to your cars VIN. My part number is 84307-76010. 76020 and 76040 were also used. My car, a 2012 model, was the same as a part found in a 2015 model..I suspect cars with heated steering wheels may use one of the other numbers..Be sure you replace the wheel in the same position it was in when you removed it..Be careful handling those wire connectors. A very small screwdriver can be used to open the locking clips that secure the connectors. Don't force them..Before you start this project, disconnect the 12 battery which is in the RR corner of the trunk to prevent accidental air bag deployment.. After an extensive search, I located a salvage yard in NJ who had a 2015 model and they sold me the entire steering column less the airbag for $60. They would not remove the clock spring and sell just that part. It cost $45 to ship the column to Denver where I had to tear it down and remove the clock spring. This learning experience primed me to tear into the operating vehicle. It was a gamble I know, but I got lucky, the dead horn came back to life and everything else worked too..So for around $100 I was able to side-step a $1300 repair at the dealership...

Have to say this post saved me HOURS and maybe even saved me from a heart attack! I can point anyone to super cheap clock springs. Aftermarket but look just like the OEM. This job only took me 1.5 hours. Thanks dude!

Thanks so much for this detailed description. I am new to the ct200h community, only had mine 3 months. It is a 2013 and the horn didnt work when I bought it used and I did not even notice till several weeks . Yesterday, my son and I replaced the clock spring and it cost me $100. You saved me a $1000 , quote from dealer was over $1100

Over five years later your post is very appreciated. I took my time, broke nothing, and still finished in less than 3 hours. I used 37 foot lbs. on the steering wheel nut, from a Prius post, felt right. Thank you for your post.

Any possibility at all to get a picture of the 3 spring clips that hold the airbag. I have no idea what I'm looking at thru either of the cover openings. Or maybe a very detailed description of how to actually find them. Is anybody aware of a youtube or any other video as how to disengage these spring clips on a 2011 model>
Thanks,
Steve

See the three spring loaded holes? Of course your looking from the back, but this will help you locate them.

where is the youtube video link??

where is the youtube video link??

I can’t find the video I previously found. I suggest printing the instructions and follow to a “T”.

I'm here to say THANK YOU. After alot of google research, your post was the most helpfull. Took my time and pictures with every step (you never know i thought). The hardest part was to find the 3 spring clips. The rest was pretty easy.

Although its not 100% accurate for the CT200H, this video shows you how its done.:

Thanks again m8. You saved me alot of headaches and alot of €'s for me and my 2013 CT200H.

Cheers

Great video! Thanks, I love learning stuff. I wonder when you buy a new/used clock spring how you could ever know it is on the correct rotation. It seems like it could be 360 deg off. I guess one could carefully count turns in both direction until it slightly resists, then do the match and count back to middle to be sure it's in the middle, but who knows if that would be the proper factory middle or not? I've never had to mess with this fortunately.

I have to add my thanks to Fairwind for posing this. $45 for the part and 2 hours of my time is well worth what I didn't have to pay someone to do. I guess you have different options when buying an aftermarket clockspring. There was an additional ring on my old assembly that I transferred to the new one. Fortunately that wasn't the part for the horn and everything works.
Thanks again!

I have a 2015 Lexus CT200 H giving problems with the Cruise Control, Horn steering wheel buttons don’t work. Warning Lights are on, airbag,etc. I replaced the Spiral clock spring but I still have the same issues. Any ideals, suggestions or thoughts anyone?
Thanks for all the information on this site. Really appreciated.
