    I have a 2001 Suburban with rear A/C, the ORIFICE TUBE is in one site of the Y that goes to the front CONDENSER and the other goes to the back unit, my question is, does it have an ORIFICE TUBE before the rear CONDENSER?



    Thanks

Hi.............
Your suburban Don't use a expansion valve.
It use a ORIFICE TUBE, that made the funtion of the expansion valve.
OK.... If you follow the THIN line coming from the EVAPORATOR to the CONDENSER, you will found.
A JOINT COPLER. just remove and in the part going to the evaporator INSIDE of the line is the ORIFICE TUBE.
Remove and put the new one.

I Know this answear your question.
Thank you for use fixya.

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.

The front a/c is not cooling, however the rear a/c is freezing. i have checked the freon and it is at 45 psi. Could it be the drier?


NO. Use your hand and find out where its cold/ hot. Small pipes are high pressure (hot) large pipes are low pressure (cold) The big can in front of the passenger should be cold. If not, it could be low on charge. The rear uses an expansion valve, so its really different than the front (orifice tube)

97 suburban rear a/c doesnt get cold but front works great


the expansion valve is in the rear ac housing and it is bolted directly to the rear evaporator. it is an actual expansion valve and not an orifice tube. the part is about $45. the interior on the passenger side has to come out along with the entire rear ac sytem.

Rear ac on 94 surburban blows warm, front is cold. Is there only one orifice on the dual air system.


The rear air has an expansion valve in the rear of the cargo area right next to the rear evaporator. There is no orifice or filter between the condenser and the rear expansion valve so if there is any debris in the line it will clog the expansion valve. The orifice under the hood is only in the front circuit so if the front is cooling and the rear is not, most likely the expansion valve is clogged and needs to be replaced.

There is a factory service bulletin on how to r&r the expansion valve. It requires some cutting since they did not design it to be replaced. Part of the service bulletin is adding an inline filter at the outlet of the condenser before the front and rear flows divide. That will keep the rear from clogging up again.

I have a 94 Suburban and I had to do this in about 1998. With the filter I haven't had any problems since.

I can't find the rear ac expansion valve on my 95 chevy suburban?


Remove two trim panels from just inside back window and just inside rear side door passenger side. They run down from the head liner. Remove seat belt bolt ( TORX HEAD ) also. Remove lower half of trim from just inside rear side door. You should see screws holding weel cover in place. The top under glass just lifts up slightly to remove entire cover. Just a few more screws and you can hinge the top cover of the duct and fan. You will now see the top half of the rear condenser and if you look down beside it you will see the expansion valve. This about as close as you will get to changing the valve though because the freon lines running to the condenser will be stuck so solidly you would have to destroy the lines on either side of the nut to seperate them. You cannot reach the valve without lifting the condenser from its tray and you cannot lift the condenser without removing the lines from it!!! Good luck!!!

Expansion valve location


raven 1g: Your car doesn't use an expansion valve. It uses a fixed orifice tube which is located in the smaller of the two A/C lines, just before they enter the cabin area of the car.
Just disconnect the line and pull the orifice tube out of the line. Be careful not to break off anything and leave it in the line.
