Hi. Thanks for your question. This seems like a technical issue. However, you can also visit https://www.reliable-store.com and download the entire service manual which will help you in fixing brake lights. It has all the information along with the diagrams for better understanding. Good day!

I own a 2006 KIA SEDONA LX the gear shifter would get stuck and not allow me to shift into gear. Remedy 1 : I replaced the brake sswitch which controls this that was not the answer.Remedy 2: In the gear shift handle a took it apart in the piece you press it would not pop back out, on the opposite side i located the cover which houses a spring which I located it was broken in three piece replaced and up and running. Good luck to all of you with this problem . Any questions you can call 661-303-1299 for clarification ask for Vince

there is something wrong with your SYNCRONIZER. it is a device located inside your transmission that is responsible for smooth gear shifting at any rpm's. i have not yet heard of syncronizer repair, so it possibly means that you just need to have it replaced. this is not a DIY job. have a transmission mechanic fix your problem

We have same problem before and the solution is replace the solenoid that control the gear change. It is difficult to do that, let KIA mechanic to do that.

shifter cable either broke or came disconnected

Mist the switch with a small amount of windex then blow it out with canned air.
