You have too much pressure on the system. When the AC is on there should only be around 50 psi on the low side. Otherwise your taking a chance on blowing the seals or blowing the compressor. with that much on the system already I would hope the safety switch has kicked in a disabled the compressor so it doesn't blow your lines.

Can a 2002 ac compressor go on to a 2003 kia sedona?


As long as they have the same part number there should be no issue. Sometimes the same part is used for four or five years consecutively. Check the part number and appearance.

Where is the expansion valve located on the 2004 KIA Sedona


Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

A/c compressor was replaced and recharged. blows cold for a few days, and rear ac not atall. Compressor now cycles on and off and does not get cold at all. has been cleaned and recharged twice now. ...


Yes. A thermal expansion valve (often abbreviated as TXV or TX valve) is a component in refrigeration and air conditioning systems that controls the amount of refrigerant flow into the evaporator. If it is malfunctioning it will limit the amount of freon available to cool the vehicle.

However, the shop should have found this issue initially, so I would only pay for the part; not labor. Call your local dealer (Chevy Tahoe/Suburban is the same) and ask what the cost is. Price sounds high. They are avl. for under $100 online.

How many pounds of r134 and how much oil ozs.


somewhere around 1.6 pounds (1lb.14ounces) of R134a if system is evacuated and 3 ounces of oil with new compressor.
keep pressure on the low side around 34-37psi & it should blow snow. Below are normal car AC pressure readings with 134A.
  • Normal readings on high and low side with AC OFF (static pressure) – Depends on outside temperature, but normally is between 80-105 PSI
  • Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s – Ranges from 25-35 PSI –
  • Normal high side reading ranges from 200-350 PSI
Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.
DIY recharge kit:
With the AC on the coldest setting, use a thermometer in a middle vent. Normal vent temperature readings will vary depending on the (ambient) outside temp. The vent temperature should range from around 42-55 degrees in my experience. If normal gauge readings are obtained and the vent air is cold – STOP don’t overcharge the system.
Thank you for using fixya and be safe.

There can be several reasons for this, easiest would be a loose wire at the compressor or a pressure switch.

If it clicks on and off it is likely over or under charged. There are safety pressure switches that will turn the compressor off if the pressure drops under approx 50 psi on the low side or approx 300-400 on the high side, it varies with different vehicles.

If the system was charged properly you are probably looking at a restriction somewhere in the system (accumulator, orifice tube, evaporator, condenser, txv etc.)

Ac not cold


Add about half of the 2nd can. Look on hood or radiator support to find the sticker that tells you how much the ac can hold.

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.

Where do I recharge ac at


there are 2 ports one for low pressure and one for high pressure. the low pressure is bigger in diameter and is usually close to the dryer and or fender and firewall. the high pressure is near the condensor on the fron of the vehicle. if there are caps for the ports low will be blue and high will be red. low side pressure should be 35-50 psi and high pressure should be 135-150 psi
