Ac Accumulator Air conditioning system is not getting cold, Compressor comes on , fresh 134a refrigerant charge. Wher is the Ac accumulator because I can not see/find it under the hood. Is it inside the dash board or this make and model does not have an accumulator? Or is the compressor bad even if it comes on?

because the temp difference between the hi and low side will be greater faster than a normally charged system the reason it cycles off is the keep the evap. from freezing up, but running to low on Freon can cause poor lubrication in the compressor causing damage to the compressor, yes it will blow very cold for a short period of time with a low charge

first of all why did you charge the system it never needs to be recharged unless you have a leak in it that being said when you turn on the ac do you hear the compressor clutch kick in and if so do you see condensation on the accumulator and does it feel cold? yes/no if yes then the vacuum door inside the car is not opening thus giving you warm air========if no the refrigerant leaked out again because of a leak ///// or the cycling switch is bad///// or there is still not enough refrigerant in the system to get the switch to turn on the compressor//// or your compressor is n/g

determine the type of refrigerant, conversion kits are available but not an easy job, most parts stores have refrigerant and connectors to add to your system, follow the directions on the can.

TO REPLACE THE AC COMPRESSOR, YOU NEED TO LET GARAGE OR DEALERSHIP DISCHARGE AC SYSTEM FIRST.YOU NEED TO FLUSH OUT AC SYSTEM USING CAN OF AC FLUSH.YOU NEED TO REPLACE ORIFICE TUBE,YOU NEED TO REPLACE ACCUMULATOR, BESURE TO ADD 1 OUNCE REFRIGERANT OIL TO ACCUMULATOR,AND NEW AC COMPRESSOR POUR OUT THE SHIPPING OIL IN A SMALL CONTAINER MEASURE AMOUNT IN AC COMPRESSOR POUR NEW REFRIGERANT OIL AC COMPRESSOR .IF NOT SURE TO BE ON SAFE SIDE POUR 2 OUNCES OIL IN COMPRESSOR.BE SURE BUY NEW AC O - RINGS AND SEAL KIT.WHEN ALL IS DONE EVERY THING BACK TOGETHER BE CHEAPER TAKE CAR TO A GARAGE LET THEN PUMP DOWN EVACULATE AC SYSTEM CHECK FOR LEAKS AND REMOVE MOISTURE OUT THE SYSTEM. YOU NEED AC TOOLS TO REPLACE AC COMPRESSOR.YOU NEED VACUUM PUMP, MANIFOLD GAUGE SET.YOU NEED AC LINES DISCONNECT TOOLS TO REMOVE ACCUMULATOR.YOU HAVE TO HOT WIRE AC COMPRESSOR WHILE CHARGING IT UP.BE SURE TO WEAR SAFETY GLASSES WHILE WORKING ON AC SYSTEMS.

The low pressure port on an AC system is between the evaporator and the compressor. The evaporator is the cooling coil in the dash. I believe you will find an accumulator just on the "out" side of the evaporator. The accumulator is a round aluminum container about 4 in. in diameter and about 7 in tall. It has a tube from the evaporator going in near the top, a tube/hose going from the accum. to the compressor and probably a pressure switch and a charging port. All these items are located around the top of the accumulator. That charging port is the low pressure, (suction side of the compressor). Don't over charge. Use just enough to get cold air from the system. I doubt this system has a sight glass in the tube near the condensor, but if it does, put in just enough refrigerant to where you no longer see bubles going past the sight glass. If this is a cronic leak, you must have the leak repaired. It is aginst the law to recharge AC systems without repairing the leak.

Thanks for using FixYa. Good luck.

TAKE CAR TO GARAGE OR DEALERSHIP.THEY HAVE TO DISCHARGE AND RECOVER THE REFRIGERANT FROM CAR STORING IT IN STORAGE RECOVER UNIT.AGAINST THE LAW TO LET OUT REFRIGERANT IN THE ATOMOSHERE CAUSING OZONE DAMAGE.WHEN REFRIGERANT IS REMOVED THIS WILL BE THE CHEAPEST WAY.FIRST GO TO AUTO PARTS STORE BUY A PACK OF O - RINGS FOR AIRCONDITIONERS SYSTEM.THEY SHOULD BE GREEN COLOR NOT BLACK ONES.THEY ARE THE UNIVERSAL O -RINGS NOT MADE FOR AIR CONDITION SYSTEM.THE REFRIGERANT WILL DESTROY AND CAUSE LEAKS.WHEN YOU BUY O - RINGS.BUY NEW ACCUMULATOR THE OLD ONE FULL OF MOISTURE.YOU NEED TO REPLACE THE EXPANSION TUBE OR ORIFICE TUBE.IT IS LOCATED AT CONDENSOR LOWER LINE FITTING.BUY 1 BOTTLE OF R- 134 REFRIGERANT OIL. THEN BUY NEW COMPRESSOR.WHEN REMOVING OLD COMPRESSOR POUR THE OIL OUT OF IT.MEASURE HOW MUCH OIL IN COMPRESSOR.OKAY TO REMOVE AC COMPRESSOR FIRST REMOVE DRIVE BELT.THEN SAFELY RAISE SUPPORT VECHICLE ON JACK STANDS ON LEVEL SOLID GROUND REMOVE WHEEL AND SPLASH SHIELD ON PASSENGER SIDE.DISCONNECT THE ELECTRICAL CONNECTOR FROM COMPRESSOR AND REMOVE COMPRESSOR REFRIGERANT LINES.THEN REMOVE COMPRESSOR MOUNTING BOLTS 2 BOLTS AT TOP 1 OR 2 BOLTS ON BOTTOM OF COMPRESSOR.WHEN REMOVING OLD COMPRESSOR.SEE HOW MUCH OIL COMES OUT.SHOULD BE A OUNCE OR TWO.GM COMPRESSOR HOLDS 10 TO 8 OUNCES.BUT WE DONT KNOW HOW MUCH IN SYSTEM.WHEN YOU BUY NEW COMPRESSOR.MEASURE HOW MUCH SHIPPING OIL IT HAS BY POURING IT OUT.TO BE ON SAFE SIDE I WOULD POUR 2 OUNCE REFRIGERANT OIL IN COMPRESSOR. POUR 1 OUNCE OIL IN ACCUMULATOR.REPLACE ALL THE O -RINGS AT THE COMPRESSOR AND ACCUMULATOR AND THE LOWER CONDENSORS LINES WHEN REPLACING THE ORIFICE TUBE.USE NEEDLE NOSE PLIERS TO REMOVE THE ORIFICE TUBE.BESURE TO PLACE THE LONG SCREEN ON THE INSIDE.BESURE TO LUBRICATE ALL O - RINGS WITH REFRIGERANT OIL.WHEN YOU PUT EVERYTHING BACK TOGETHER.DONT OVER TIGHTEN THE REFRIGERANT LINES WHICH WILL CUT THE O - RINGS CAUSE LEAKING. TAKE CAR TO A GARAGE THAT DOES AC WORK.LET THEM PUMP DOWN THE SYSTEM AND LEAK TEST THEN CHARGE AC SYSTEM UP.THIS WILL SAVE YOU MONEY BECAUSE IF YOU BUY A VACUUM PUMP THATS ABOUT $400.00 AND MANIFOLD GAUGE SET A GOOD SET RANGE FROM $100.00 TO $300.00 DOLLARS.SEE YOUR AC COMPRESSOR $270.00 TO OVER $300.00 THAT ADDS UP.HOPE MOST THIS INFORMATION WILL HELP YOU. IF YOU HAVE ANY PROBLEMS THE HAYNES REPAIR MANUAL CAN ALSO HELP YOU IT HAS PHOTOS AND INFORMATION HOW TO REMOVE AC COMPRESSOR.

Follow the large tube/hose coming out of the dash to a large aluminum canister that then has a hose or tube that goes to the compressor. It is probably located on the side of that canister (the accumulator) under a little blue screw on cap.. WEAR EYE PROTECTION AND GLOVES WHILE HANDLING REFRIGERANT!

find the sensor that is plugged into the accumulator on passenger side normally it Will have two wires the dryer will be silver or aluminum colored unhook the connector put a paper clip in the connector if the compressor comes on then you have it, Warning if low on refrigerant you can damage the compressor if on for a long period of time, check to see if AC gets cold turn it on to Max AC fan full blast and see it it's cold, if it is the switch is bad, if it does not get cold then it needs to be serviced.

Charging the A/C system is really simple. I have a '98, but don't know why a '97 would be much differrent. So, see if this works for you.

You will need a charging hose with a guage and two or three cans of refrigerent (R-134A). If your system is out of refrigerent you have a leak. So, make sure one of the cans you buy has marking dye in it so you can figure out where the leak is. Depending on how large a leak you have, it may take several weeks and months or just a few days. Most canned refrigerents have a sealing material that may plug the leak for an extended period of time or even permanently.

With the engine running and air conditioning on, disconnect the harness from the low pressure switch on the accumulator (left side of engine compartment).

Use a small wire to jump acoss the two contacts, the compressor clutch should engage and the compressor should start turning.

With the refrigerent can attached to the low side hose (blue connector), connect the hose to the low side port on the accumulator.

Open the valve on the charging hose. Refrigerent should start flowing. Shake can periodically refrigerent is drawn into system. Can will feel very cold and probably begin sweating as the refrigerent evaporates and is drawn into the accumulator.

There should be technical sticker under the hood to tell you how much refrigerent to charge system with. When it reaches the correct pressure 25 to 45 psi depending on ambient temperature, you are close to the correct charge, (most gauges you get at auto parts stores have a "blue zone" to indicate proper charge) close charging valve and disconnect the hose from accumulator. Though you can't tell exactly how much refrigerent you've put in, by knowing how much is in each can and how many cans you put in you will have a pretty good idea.

This will all go fine as long as you don't have a bad compressor or other sealed system problem.

Good Luck!
