Re: 1994 Grand Cherokee Laredo Blocked Orifice tube
I have a 1994 jeep laredo. When I make a u turn there's a loud sound while making the turn and the car starts skipping until I turn the wheel straight. What causes that?

I cant find my orifice tube location a 2007 dodge ram 1500 with a 4.7 engine. Might be better to put this in the 3rd gen Ram forum instead of 2nd gen Dakota.
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 !
Rather then guessing an just replacing parts , have a qualified repair shop hook up A/C manifold gauges an check the system . Can tell you what's wrong in just min.
(it is only blowing slightly cool air. I suspect it is the orifice/expansion tube and want to know if I can change it out myself or reair it.)
Don't suspect , that's guessing . test don't guess . Are the A/C pipes going in through the fire wall cold ,have ice on them when A/C is on ?
HI, if your looking for the A/C expansion valve it has been replaced by what is known as a fixed orifice tube.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
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
