Apparently you have an older car, and it has R12 freon. You do NOT need a license for 134, but you do need a license for the R12. In addition to do this changover, you need special training, and the proper equipment, this is not just a simple process.

How hard would it be to add AC to a 2004 Cavalier Ecotec?


NOT HARD TO ADD BUT YOU NEED A MANIFOLD GAUGE SET TO CHECK AC REGERANT LOW SIDE SHOULD BE 32 - 65 HIGH SIDE SHOULD BE 150 - 325 PSI. DONT PUT ANY REFRIGERANT IN AC SYSTEM IF SYSTEM NOT LOW.PROBLEM COULD BE ELSE WHERE COULD HAVE MOISTURE IN THE AC SYSTEM. CONDENSOR COULD BE OVERHEATING COOLING FAN NOT RUNNING OR AC AIR DOOR NOT OPENING.IF AC REFRIGERANT LOW THE LOW CHARGE PORT NEXT TO REAR STRUT TOWER ON PASSENGER SIDE LOOK FOR SMALL REFRIGERANT LINE WITH CAP GOING TO ACCUMULATOR THE THE INTO FIREWALL TO EVAPORATOR THATS YOUR LOW SIDE.GO TO AUTO PARTS STORE BUY AC R-134 RECHARGE KIT AND WHERE SAFETY GLASSES PROTECT EYES.

2002 acura tl a/c compressor comes on but no air comes through vents.


You need to get your AC recharged or you can purchase a kit to recharge your ac. In the kit is the instructions to recharge your AC. You could purchase a kit at wal-mart or any parts store. Below is a picture of the "Quest Auto A/C ReChill kit" that can be purchased at Napa.

Ac does not work i don't measure powere to the


If the fuse is ok, and you are getting no power to the compressor, then it's possible that the a/c switch in the dash is bad or loose, or it's possible that there is a problem elsewhere in the circuit.

As a test, try wiring the compressor directly to the battery to see if it comes on. If this checks out ok, then pull the switch from the dash and test it. If the switch is ok, you will need a circuit diagram to track down the problem in the circuit.

PS. Just in case you didn't know this, if the refrigerant pressure in the system is too low, the compressor will not come on. Sometimes this is mistaken as a sign that the compressor or circuit are bad. Make sure that your system has a sufficient load of refrigerant. You can get an inexpensive R-134 pressure gauge included in a recharge kit from most discount stores or auto parts stores.

What do I need to replace to convert my ac to r134a on a 88 chevy s-10 blazer


need to have the a/c system evacuated and flushed out with the appropriate cleaner.Replace the orifice tube and drier, and purchase a retrofit kit at any parts house. Recharge system with appropriate amount of oil charge and freon. It will take less R134a than it did R12.

My air conditioning is not blowing any cold air.


It shoud have R134a, I would use a recharge kit. If you have a slow leak this will only be a temporary fix. They usually sell a kit with a dye inside the can, If you use that you should be able to locate where the leak is.

Replaced condenser, want to recharge with 134 rather than r12


you only need to buy a conversion kit if the system used r-12. but i dont think it does. the amount u need would be on a sticker under the hood somewhere attached to either a a/c part or check by one of the strut mounts

Refrigerate 134 kit


the hook up for the kit is closest to the ac condenser.there will be a black cap on it that you have to remove to hook up the line for the refrigerant and you must have the vehicle running with the air on to recharge it properly,there should be paperwork with the refrigerant that tells you the reading you need to show the system full etc.

Where do I hook up the R-134 AC repair / recharge kit?


look back near the firewall right beneath the bottom of the windshield. There is a small black cover that you unscrew, and hook the ac recharge kit onto. Then just follow the directions on the can.
