AC BLOWER NOT BLOWING

it should be in your hanbook if you have not got it try looking on the fuse box covers in the trunk under hood in the cabin lower A post plus there may be 2 more fuse boxes under the rear seat kick panels depends on model/year

first i would try checking relays,fuses, and the ground cables. replace as neccesary....now for checking the ground cables.....i would disconnect them and try scuffing them up with a wirebrush or something that will scuff up the metal a little bit then re-attach them.....test the blower and see if it works.....let me know what happened.

check freon level first. You should hear the compressor clutch kick on under the hood when you turn it on. Can you hear and see it come on and start spinning the compressor?

does it blow on any speed??? if not turn the blower on and find it usually under the left side of the dash, take any object and knock on it, if it then works, it needs replacement

Check your heater core for leaks. Do you smell any antifreeze? If so, good sign of heatercore failure. IF air is blowing good, then heater/air blower motor is fine.

The compresor can be damaged from to much or to little gas..

I would have it checked..

chek the blower regulator its a common problem on digital a/c control

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.

Sounds like plastic, leaves, or paper got sucked into the ducting, to the fan, on the blower. You'll need to access the blower motor, remove it, and remove the objects. Not sure, would be in your owners manual, but if you car has a clean-air cabin air filter. You may be able to remove the debris from there. Good Luck.

hello,seems your blower regulator or resistor is defective,hoping your blower motor is not stuck-up,ty
