    The belt is good. The compressor clutch does not engage. I checked the hi pressure switch ad it seems ok. Not sure if it has a thermal cycling switch or low pressure cycling switch.

    How is the belt? Do you see the pully clutch engage and disengage when turned on and off? Does the AC coil at the radiator get hot as it should?

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 when the A/C was on. I would check this then check the coolant pressure.

2003 kia sedona Replaced the C/fan H2 relay switch ran fine a few mins then a loud rumble near the front fan and smoke appeared. Switched them back no sound / smoke but now the ac is blowing hot air


Im going to guess that the cooling fan went bad. Smoke is a pretty good indicator that something is no good. It make have blow fuses that also power the A/C compressor. The C/Fan 2 fuse is the one that the compressor uses as well.

Kia sedona compressor clutch does not turn?


check for fuse and relay problems in the ac circuit. disconnect the wire near the ac clutch and use a test light to see if there is power there. Remember that there are 3 units that will stop the clutch from working. Low pressure switch, high pressure switch and the thermostat. Best take it to an accredited ac specialist shop for a test of the system as you may have a leak and all the gas is gone.

2003 Kia Sedona replaced low beam bulbs checked fuses still won't work high beams n fog lights work can u help


IF THERE IS NO POWER AT EITHER LOW BEAM LIGHT SOCKET & YOU ARE SURE ABOUT THE FUSES, SWAP THE WORKING HIGH BEAM BULBS WITH THE LOW. IF THAT DOESN'T DO IT YOU NEED TO REPAIR OR REPLACE THE BEAM SELECT SWITCH, { DIMMER SWITCH } KNOWN AS THE COMBINATION SWITCH, UNDER THE STEERING WHEEL. CAN USUALLY BE DONE WITHOUT PULLING THE STEERING WHEEL. TEST BEFORE BUYING, MAY BE COSTLY. GOOD LUCK , DR.VOLT

I have a 2003 Kia Sedona. The A/C Compressor will not kick in. Checked all fuses and relays and nothing? A/C was working good then all at once it quit.


Same happened to ours- full of coolant but no cold air. Turned out to be selector switch in the console. Replaced and worked fine for about a year, now works only intermittently again.

The air conditioner in my 2203 Kia Sedona stop cooling. All I am getting is warm air.


You may need to have the A/C recharged. It maybe low on freon.

My fly wheel to the air conditioner dont move on my 2003 kia sedona


There is no fly wheel on the AC compressor, however there is a clutch assembly that in gages and dis in gages when the Ac is turned on, if it does not spin when the A/C is no it is most commonly caused low refrigerant in the Air conditioning system. The system will have to be tested for leaks and repairs made and maybe a low pressure switch replaced in order to fix this.

AIR CONDITIONER QUIT WORKING


Pop the hood, start the vehicle and turn the AC on. Watch the compressor, it should have a center that rotates on an off and you should hear a clicking sound. This is the compressor clutch you are looking at. If the compressor is not doing this, check the fuses for the AC. If the fuses are good, then most likely the high side sensor switch is not working, therefore the clutch never engages and the air never gets cold.

Try that and get back to me, ok?

2003 Kia Sedona, A/C stopped blowing cold air without any warning


do a pressure test. You may have lost freon to the point where it will not let the compressor come on. If you do not have any gages or access to a gage, buy one of the cans of freon that has the low pressure gage attached. Make sure you get the one that has 134A with sealer. The pressure should be about 100psi not running and go down to about 60 when it is running. IF you have a slow leak and the system is low, the compressor will not come on. If you get very low or no pressure when you hook up the can, don't waste your money, have the system checked for the leak. You must vacuum the system down to 30 inches of vacuum before refilling if it is empty, and it does not good to fill it if it is just going to come back out.

Hope this helps

Air conditioner started blowing hot air


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.
