Air conditioning on 2002Jeep Grand Cherokee does blow cold enough Added charge to low suction line but still blows the same also the same line seems to have moisture where the aluminum and rubber meet


To much refrigerant will be the same as to little ! You should take it to a certified technician you knows what he's doing ! Technicians such as myself have to be certified to fix A/C system , they should not sell refrigerant to the public ! Did you change the orifice tube or the THX valve , which ever it has ! Sounds like it's plugged !

Were is the expansion valve on a 1995 grand cherokee


HI, if your looking for the A/C expansion valve it has been replaced by what is known as a fixed orifice tube. You will find this located in the line running from the condenser and the evaporator. you will need to remove the line and you will see a plastic tube inserted in one end. You may need a pair of needle nose pliers to remove it. good luck

A/C problem with 99 Jeep GC Laredo


If the compressor is running and the lines are getting cold that leaves the evaorator having a block, don't recall if that year has the orifice tube or not. In any case it is going to require opening the systems cleaning the lines and the oriffice then refilling the system. That means a vacuum pump and refriedgerant oil and the associated guages and freon. Live on the Gulf coast and you are right we do get hot down here!

Looking For orfice Tube on 2000 Grand Prix 3.8 Liter .need to change it if it has one along with accumalator


Recover the refrigerant. Remove the engine air cleaner.Remove the vacuum brake booster. Remove the condenser tube. Remove the expansion (orifice) tube: Use needle-nose pliers in order to grip the orifice tube. Use a turning motion along with a push-pull motion in order to loosen the impacted orifice tube. Remove the orifice tube.
Important: DO NOT use any solvents or chemicals to clean the expansion (orifice) tube porous plastic inlet filter. Inspect the expansion (orifice) tube for the following conditions and clean or replace with a new tube as indicated: Broken plastic frame, Inlet filter damaged or plugged with fine gritty material, replace tube. Inlet filter coated with metal chips, flakes, or slivers; coating may be removed with low pressure shop air ONLY and reused if cleaned satisfactorily. If reusing the tube, discard the O-ring seals and replace. This is from the gm service CD manual. keep me posted and good luck

Where exactly is the orifice tube located at on a 1996 (DOHC v6)?


it's in the high pressure liquid line.

A/C Evaporator Core Orifice The A/C evaporator core orifice (19D990) should be replaced whenever the A/C compressor (19703) is replaced for lack of performance (internal damage). The A/C evaporator core orifice, located in the condenser to evaporator tube (19835), cannot be serviced in detail as a component of the line. If replacement is necessary, follow the procedure outlined for Liquid Line Removal and Installation. An orifice tube replacement service kit may be used as an optional service procedure. Refer to Section 12-00 for information regarding the use of an A/C Evaporator Core Orifice Replacement Kit E5VY-19D695-A.
-----------------------------------------------------------------------------------
A/C Evaporator Core Orifice Replacement Kit Installation
  1. Discharge A/C refrigerant system. Refer to System Discharging and Recovery as outlined.
  1. Remove condenser to evaporator tube (19835) from vehicle.
  1. Locate A/C evaporator core orifice (19D990) by three indentations or a circular recess in metal portion of the condenser to evaporator tube.


    A/C Evaporator Core Orifice Location

  1. Note angular position of ends of condenser to evaporator tube so that it can be reassembled in correct position.
  1. Cut a 63.5 mm (2.5 inch) section from condenser to evaporator tube at A/C evaporator core orifice location. Do not cut closer than 25.4 mm (1 inch) from start of a bend in tube.

  1. Remove contaminants from the two pieces of the condenser to evaporator tube.
  1. NOTE: The inlet half of the condenser to evaporator tube will be positioned against the A/C evaporator core orifice tabs when correctly assembled.

    Lubricate fitting with clean refrigerant oil and assemble orifice tube kit (with A/C evaporator core orifice installed) to condenser to evaporator tube. Make sure flow direction arrow is pointing toward evaporator end of the condenser to evaporator tube, and taper of each compressor ring is toward compression nut.

I believe the orifice tube on this model requires the a/c pipe to be cut to install a new tube. You need to discharge the system, replace the tube, then evacuate miosture with a vacuum pump, then recharge with R134A refirgerant. Not a job for a non technical person.

The oriifce is in the line just before the evaporator that is in your car a/c heater case. It is where the liquid refrigerant turns into a vapor as it comes out of the orifice and then it absorbs heat from the air going into you car, thus blowing cold air. Moisutre in the warm air condenses and as he iar gets cold and it drains out of your evaporator and out the drain & onto the ground
