Decided to take the car out for a drive since it's been a few months. Car is a 2018 zl1 with just over 10k miles. Anywho, I got in the car, closed the door and when I did, the little plastic plate that is the cruise control + and - decided it didn't want to be apart of the steering wheel anymore. from the looks of it, the left side that should connect to a post was broken. Is there anywhere to get just that plate or do I have to buy a whole new assembly?

And other question, if it's the assembly, any way to replace it that doesn't involve taking the airbag out?


Edit, here is a pic of said part I'm talking about.

If the picture accurately reflects the component you are trying to replace, ie heated steering wheel and no collision detection.
Then for a 2018 ZL1 I believe the part number you want is: 23379500. Which can be had for $25 to about $50 depending on source and condition I.e whether used or new.

But again I would verify that part number is the right one you are looking for. Hope this helps you out!

23379500 is the part # that matches the one I got on my steering wheel. I was just hoping they sold the small plate seperate and a way to put it on without taking the airbag off.

Did you ever fix the issue? I had mine pop off also on my 2018 2SS. I ordered the part but I’m wondering if I can just take the plate off. Thank you in advance.

My apologies for not updating.


To answer your question, no you cant just take the plate off. trust me, I was really hoping you could.

I got the part off Amazon (cheaper than GM) and installed it.

So taking the airbag off and moving the stuff out of the way was super easy (though the pins you have to push in to release the airbag are pretty tough). I added the youtube video below that was really helpful (to me). Obviously you don't need to go as far for the paddle shifters, but its enough to get the whole plastic bezel off. again, pretty straight forward.

Now, getting the old module out its a huge pain. Mostly because when you get that plastic bezel off and flip it over, you will see there are like 5 plastic tabs that hold the module in. 4 are easy to get up with just alittle positive pressure the 5th is in the corner and it literally felt like I was about to break it before it finally went over the "lip" of the old module. but once it was out, just instlal the new one, plug in the few wires and snap in the air bag.

1st time I did it, I wanna say it took me about 30-40 mins. I say first time cause when I was done and went to test it, it didnt work. the orange light didnt even come on saying it was on/had power. So the 2nd time when I took everything apart, I saw it didnt plug on 1 of the wires. Plugged it back in and reassembled. Took 5 mins

Thank you for the reply my friend! I will give that a try. I been searching everywhere for someone with the same issue as me.�� I appreciate your help!

My biggest advice is just take your time when you get to those tabs. The rest is super easy.

Since I just did this (replaced a cruise control / heated steering wheel switch assembly on my 2019 ZL1 1 LE, cruise control + and - buttons broken off when I got the car at 20k miles), here's my advice:

1. Set your driver's seat in a good position (possibly much farther forward and seatback more upright than your normal driving position) so you'll have good leverage on the wheel when you're releasing the airbag spring retainers. Also set your windows where you want them before you disconnect the battery.

2. Disconnect the battery, wait at least 10 minutes before starting to mess with the airbag (not sure if 10 minutes is actually long enough or if there's even enough capacitance in the airbag circuit to trigger anything, your call on how long is long enough).

3. It IS necessary to completely remove the airbag from the wheel to replace the CC switch assembly. I was hoping once the airbag was mechanically unclipped, I could do the switch replacement without unplugging the three wires for the airbag... nope, the airbag has to come out because the black ring-shaped plastic trim piece that is trapped behind the airbag that contains the two switch assemblies (CC/heated wheel on the left, info center buttons on the right) must be completely detached from the steering wheel to pop out the switches from behind. It is also necessary to remove the ZL1 badge at the bottom of the steering wheel (it simply pries off; there are four friction-fitted legs behind it that press into the wheel rim behind it) because there is a lip at the bottom edge of the ring-ahaped trim piece that sits behind the ZL1 badge.

4. Using a small flatblade screwdriver or a 5/16" Allen wrench to release the spring clips through the small holes: the hex wrench hits and stays on the spring clip release better than the flatblade screwdriver, but the hex wrench hurts your hand more when trying to extert pressure to release the clip. I found the screwdriver works better, but orient the flat of the screwdriver *parallel with the steering column* so it doesn't slip off.

I had to jam on the screwdriver HARD to eventually get the airbag to come out. I spent over an hour on just removing the airbag. It was very frustrating. It seems like how difficult it is to remove the airbag varies a lot from car to car. In my case, the airbag was tightly friction-fitted in place on both sides, so even with the spring clip fully released, it took a lot of repeatedly pulling on the airbag top (by hand, you can't pry it out because the soft vinyl of the airbag cover will simply deform around the tool you're attempting to use) to eventually walk the airbag out. My airbag also looked like the idiot previous owner had managed to pour a very sticky substance into the crack between the airbag and the top-side steering wheel trim (a cherry Slurpie??) so my airbag may also have been "loctited" in place on my car.

5. Once you've got the airbag out, unclip the 3 wires and remove it completely. Set it down somewhere face up, in case some poltergeist manages to set off the airbag, it'll just inflate explosively, not catapult itself somewhere at 300 mph.

6. Getting the black plastic trim ring off the wheel will require careful pulling and probably prying behind the trimpiece to release all the clips that hold it to the wheel. Remember that you will have to remove the rectangular trim piece at the bottom of the wheel first in order to remove the ring-shaped back plastic trim holding the switch assemblies.

7. Try to be patient and careful with swapping out the switch assembly... if you're like me and not a particularly patient person, you may be all out of patience / Fs to give at this point and accidentally break one or more of the very weak/soft fake metal finished switch bezels that the switch assembly clips into... take it easy! Serenity now! But, even if you did break enough of the tiny retainer clips so that the new switch assembly is loose, you could use a little Permatex or JB Weld to secure it... none of that would be visible once everything is reinstalled.

8. Reinstalling the trim ring w the newly replaced CC switch is "the opposite of removal" as they say. Be gentle, be careful not to snap off any of the multiple mounting legs as you reinstall it... pay attention that each one is lined up / started into the matching hole on the wheel before using force to reseat the trim piece. Reinstalling the airbag after you're done with the switch and trim ring replacement may take more effort than you think, as the horn button functionality of the airbag soaks up some of your force as you push on it to try to get it to seat properly / clip back into place.

The cruise control / heated seat switch assembly I used was from eBay, shipped from China, assumedly not a real GM part, but it looked very very similar to the part I took out... it was under 30 bucks shipped when I ordered the part in April 2025 but now in November 2025, the cost looks to have gone up significantly, probably tariff related.
