They are located underneath the coils on top of the valve cover or valve covers if its a V6. You cant see them untill you remove the coils from the top of the valve cover. Look down in the hole and you will see the Spark Plug. Good luck.

One thing these audio shops do sometimes is drill through the firewall and several times in my career have seen where they have drilled through the harness and repaired with **** connectors and it does not work. They need to recheck all of their work. When I put radios in any of my cars, I always buy the harness which splices to the radio harness and then allows you to simply plug the wires into the vehicles harness so everything works properly. Did they install a sub woofer, amp or anything else that may require a seperate power wire? Make sure either they fix properly or send it to Kia to have the wiring harness replaced (I have done this too) and they pay for it! Let me know if you need anything else.

There may be a problem with your a/c compressor or there may be a leak in one of your a/c lines. Most likley your problem is coming from a leak in the system. In order to do a proper stop leak test with dye, it would be advisable to make a trip to your local mechanic and ask for an a/c check. If you want to aviod the shop you can try and use stop leak to see if that works, but chances are if there is no cold air at all then the leak you have is significant.

Hope this Helps!
