My car passed smog, but mechanic will not give proof until check engine light is operable (light does not light up when starting car). Trying to figure what is involved in replacement procedure of bulbs and where to buy replacement. Do I have to buy a "cluster" or one bulb? Thanks

Hey Anopro,

You must remove the instrument cluster to replace the bulb, Use a flashlight and shine it onto the cluster so you can see which one to replace. Here is a guide to help you. I shows doing a shift light but you get the idea.

Please let us know happens so it will help others.

Best, Ken

Wow! Impressed with quick reply and the bulb part # is crucial since the dealer couldn't find it in his data of bulbs!! Thanks so much. Hoping this is a DO it yourself and my son can easily open up the dash- Thanks much!

Hi Ken- thanks to you I ordered the part # for the bulb and it arrived. The mechanic is now telling me that there is a "potential problem" that once the check engine socket is checked it still might now work with the new bulb! I was shocked to hear him say the computer itself may be inoperable which is very very expensive to replace
I said the other lights are on -oil brake seat belt etc but he said the check engine has a separate computer----and he won't know until he gets in there if it's not working
Is there any way you can point me to this issue online or if you have knowledge of this KIA issue or how to approach it would be so helpful! Thanks and I have told a bunch of people about your great service.

I would replace the bulb to see if that works first. Also check all system fuses.

Let me know what happens.
