#67 of 76 Radio knob problem, 2009 vibe
Jan 16, 2013 (12:08 pm)
I just read a message about repairing the broken knob on my radio but I can not recover the message again. Please post it again. It discribed removing the rear plate to access the front and removal of the broken button. I am a retired elctronic engineer and feel confident I can repair it if I can find the right replacement parts. Both knobs are broken on my radio. Thanks for all the help in advance.

another method is to trim off (hacksaw) the front of the broken knob to expose the raised area preventing the broken knob from being pulled out from the front. Snip off the rest of the broken piece and discard. Once off, you can use a dremmel or your favorite tool to trim off the raised area of the new knob and then slide it on the radio's stem. Why do it this way? Because the cause of your problem is that the plastic sleeve inside the original knob is cracked and can no longer grip the stem inside the radio. The new knobs are the same, with the same plastic that will break again and again over time. With my method, the next time my knob's plastic core breaks, I simply pull the knob out of the radio since I have already trimmed off the raised area. I have two more radio knobs already trimmed and ready to go when my existing ones break again some day. Since Toyota/GM has not come up with an improved replacement for the knobs, I don't see much point in pulling out my radio every time, and then tearing it apart simply to put on a knob.
#69 of 76 Maxx4me Question on knob
Feb 01, 2013 (8:22 pm)
Just picked up a 2009 Vibe with a bad knob and am not very familiar with this issue or repair. What exactly do you mean by the "raised area" of the knob? Would love to obtain something (drawing or picture) that would show exactly what to cut off or a before and after drawing or picture.
Any help you can give would be appreciated.

Two picture tutorials in the link below will outline different solutions. One is on how to remove the radio and back plate to access the knob, and the other is what I recommend: sawing and snipping off the knob at the front, trimming off the raised area of the new knob so you can simply slide it on from the front without removing your radio. Why do I recommend this? Because any new knob you put on will fail again. The metal piece that separates from the plastic inside the knob (shown in the enclosed link) will separate again at some point in the future. I don't think you want to keep taking apart the whole radio each time the piece fails. The raised area is the back part of the knob that is stopping you from simply pulling the knob off in the first place. By trimming off that raised area on your new knob, you will be able to slide your new knob on/off without removing your radio when your new knob fails again sometime in years to come.

Thanks...understand the problem better now.
If I understand this right, it's the flange that flares out at the back of the knob that prevents it from being removed by simply pulling it out...correct?
If I use a Dremel tool to cut the cap off of the knob, the next challenge is to somehow break the plastic flange into pieces so the remaining knob can be pulled out...correct? Suggestions on how to do that gently? Can you drill thru the knob and weaken it?
Then using some form of sanding tool, trim the flange diameter so that it will just slide into the hole left by the removal of the old knob...correct? That would leave the smallest amount of light coming from behind the knob.
Thanks for the help.

one of the pictures shows the three tools needed to do the job. I actually took mine to the dealer who performed the frontal lobotomy procedure successfully using a dremel tool. As you saw from the last picture in the link, as was the case with my radio, a small nick was evident after the procedure since the surrounding casing is also plastic. But yes; the key is to snip the raised flange that is preventing you from pulling the knob straight out, and then trimming off the flange on the new knob so you can just slide it on. The new knobs have the metal core inside them so you don't have to take the core out of the old one and insert it into the new one. You can buy these knobs on ebay or from your GM dealer. It is the kind of job worth trying yourself because if you are unsuccessful at removing the raised flange, the most you are left with is a broken knob; same as before. I don't think it is difficult. You just have to be mindful not to ding the plastic casing on the front of your radio

Got two knobs on order, second in case I mess up the first. I plan on duck taping the area around the knob to help protect it. I'll work on trimming the bell shaped flange first before I start trying to remove the old one. As my current knob is still useful about 20% of the time, I'll probably wait until the weather gets warmer before I start working on it.
Thanks again for all of the help.

you are welcome; and also, I don't notice any increase in the back-lighting shining through as a result of my new knob not having the raised flange. I too have a second one in reserve in case the same thing happens to my channel tuner knob or more likely, when my volume button fails again. I tend to leave my radio on all the time now and not push it to turn it on/off. I'm sure that will lengthen the lifespan of my current knob.

i wanted to throw this into the conversation about the Vibe radio. We just bought a used 2009 Pontiac Vibe and I was very surprised to find that the radio volume control knob spun uselessly around & around to no effect. We asked the dealership to fix the knob but they said they had to replace the entire radio unit! Which they did--at no charge. So far we love the Vibe!
