Either AC compressor or AC clutch failure or both highly likely as Kia Sedona has notable history of this

Sure, one might trace the wire that connects to the compressor, and while its challenging to reach without removal of both fans, it does follow upward into the engine wiring harness. At that point its much more convenient to push a needle into the wire and connect a meter to it to see if it is energized when AC selector on, cabin fan on and cabin thermostat set to coldest setting.

If no voltage then check fuses and try swapping idential relays in the engine compartment box to be sure. If voltage present, then assume the worst.

More important is why the failure. I'm convinced a design error by Kia relative to the suction or low pressure hose is the root cause of such frequent AC compressor or AC clutch failures. You can buy a new Kia OEM suction hose, position it for to install and observe immediate kinking and or collapse. Kia has likely long been aware of this problem but never conducted a recall. You can solve it permanently, toss your existing suction hose and buy this one: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=181880844799

If you buy a "Tough One" brand replacement compressor and filter/dryer together from Advance Auto Parts it has a lifetime replacement warranty. No other compressor is sold with a lifetime warant for a Kia Sedona, not even from Kia itself.

Your a/c compressor is not working.
you have to have the system checked by an air conditioning place or the dealer as to what the cause is.

Check the metal part of the heater core lines at the firewall if you can get to them and see if one side is noticeable colder than the other. At least one of them should be hot or you have a bad thermostat. If both are hot than your hot/cold actuator inside is having a problem

Air won't blow cold


Our Sedona had a similar problem, Turned out that the pipes to the rear heater had corroded and were leaking, caused some overheating which blew hot air even when the A/C was on.

Air conditioning electrical diagram for 2004 kia sedona


I also have a 2004 Kia sedona with approx. 80,000 miles on it. The air conditing system stopped blowing cool air into the car. The fan would work, but would not blow cool air. After doing a lot of research. After trying to find a car repair manual or diagrams for the Kia Sedona with no luck. We ended up taking it to our machanic. He then replaced the compressor and it is working fine now. I now know that this is common for the compressor to go out on this van.
