Live in houston, tx. a'c is working but not cooling well. checked with gauges and both in danger zone. released pressure and started refill. clutch kicks in with or without 134a induced and just seems to cavitate when filled?????

Your best bet would be to take it to a qualified repair shop so you don't get hurt !

Either you have moisture in the system or you have overcharged it.

Refilling a cars AC system is a specialised job and should not be handled by the owner ,you need a special machine to regas a vehicle where you drain it and measure the amount of gas in the system then add oil and leak dye then regas to the correct weight of gas.Here in europe you cannot buy a can of gas as its classed as a dangerous substance ,only a authorised garage can purchase gas in a 12kg cannister to refill the AC machine and the operator must hold a certificae to use the machine ,so to check out why and what you must take the vehicle to a authorised garage .

Could be low on gas.

do you have a temp gauge or light? make sure the radiator is full, if you have a gauge start the engine and let it idle for about 15 to 30 minutes and see how far the gauge will go up but if it almost reach the dangerous zone turn the AC on and see will the gauge move back down to normal zone if the gauge do move down that mean the cooling fan is working with the AC on but if the gauge do not go down with the AC on that mean the cooling fan is not working you can check the cooling fan by connecting the red wire to the + post on the battry and the black wire to - post on battry and if the fan work it is good then check the cooling fan relay and wiring.

I would suspect you have a bad A/C compressor. When you engage the A/C, the clutch locks up the pulley which kills your motor from the drag on the belt. Replace the compressor, evaporator and valve, then recharge system to 55 psi.

YOU NEED A R-134 GAUGE SET TO CHECK LOW PRESSURE SIDE AND HIGH PRESSURE SIDE.YOU ALSO CAN BUY A LITTLE CHEAPER GAUGE TO CHECK YOUR AC LOW BLUE SIDE AND HIGH RED SIDE AT ANY AUTO ZONE OR ADVANCE AUTO PARTS.WHAT YOU DO WHEN YOU GET YOUR GAUGE SET HOOK GAUGE TO LOW PRESSURE SIDE BLUE CAP PORT AND GAUGE TO HIGH SIDE PRESSURE RED CAP PORT.YOU CRANK CAR UP GET IT OPERATING TEMPERATURE.THEN TURN AC ON HIGH COOL LET RUN 3 TO 4 MINUTES.CHECK LOW SIDE GAUGE READING SHOULD BE 28 - 32 PSI. HIGH PRESSURE SIDE GAUGE SHOULD 199 - 228 PSI. THATS NORMAL CHARGE. SEE YOU CANT JUST RECHARGE AC SYSTEM UNTIL YOU CHECK IT FIRST YOU WILL DAMAGE SYSTEM .NOW YOU CAN GO TO AUTO ZONE PARTS BUY A CHARGE CAN WITH GAUGE AND HOSE.ATTACH TO IT.YOU NEED MORE THAN ONE CAN.WARNING MAKE COMPRESSOR IS RUNNING WHEN YOU TURN ON AC .BECAUSE IF COMPRESSOR NOT RUNNING CHECK FUSE AND AC COMPRESSOR RELAY.IF BOTH OKAY.YOU COULD HAVE OPEN CLUTCH COIL A FAULTY LOW PRESSURE SWITCH WILL CAUSE AC NOT TO WORK. IF LOW PRESSURE GAUGE BLUE SIDE PRESSURE IS 28 OR 30 YOU DONT NEED A CHARGE.PROBLEM SOME WHERE ELSE.BE SURE TO WEAR SAFETY GLASSES WHEN WORKING ON AC SYSTEM.

Most common cause is that your A/C system is low on R134a and needs to be recharged. All A/C system has small leaks through O ring's ect. Once the pressure is to low in the system, the clutch will not operate to keep it from burning out. The R134a is mixed with compressor oil to keep the compressor cooled and from seizing up. You can buy a recharge kit with the gauge at Auto Zone or Wal mart for just under $50.00, That includes two cans of R134a and the hose with the gauge, just follow the instruction. If the A/C works after recharging and stop's working again within 2 weeks then there is a large leak that needs to be addressed before the next refill. Good luck and hope this helps, before you go through all that check the fuses. good luck and keep me posted, be glad to help.
