tighten the belts they are slipping

Hello, It is possible to replace the compressor, you will need to remove the lines from the compressor unhook the plug from the compressor, remove the belt, then remove the bolts holding the unit in. After Replacing the compressor you WILL need to recharge the system with R134A coolant and oil. DO NOT FORGET THE OIL AS THAT IS THE ONLY LUBRICATION THAT THE INNER WORKING OF THE PUMP. Most all auto stores will have 1) A recharge kit ( I recommend getting the ones that have a PSI gauge on them that will let you know when you have the correct amount in the system) And 2) The oil simply ask for both and they will know what your talking about. Oil first then the charge. The bottle will also include some helpful guidelines to correctly charge the system. Hope this helps you.

Hello MCOMSTI You have a freon leak that MUST be found & repiared so the system will keep the charge.A fast leak is eaiser to find,look for a oil/grease stain anywhere on the system,when you loose 1/2 system charge you make ice.

YOU TAKE TO A GARAGE LET THEM PUMP IT DOWN FIRST MAKE SURE YOU PUT THE RIGHT AMOUNT REFRIGERANT OIL IN COMPRESSOR.IT COME WITH SHIPPING OIL IN IT BUT YOU HAVE TO POUR IT OUT.PUT IN THE RIGHT AMOUNT OF REFRIGERANT OIL IN COMPRESSOR LOOK IN OWNERS MANUAL TO PUT IN THE RIGHT AMOUNT.NOW IF YOUR OLD COMPRESSOR SEIZED OR LOCKED UP THEN LET GARAGE FLUSH OUT METAL SHAVINGS OUT .IF YOU DONT FLUSH OUT SHAVINGS THE NEW COMPRESSOR WILL BE DESTROYED.ALSO YOU HAVE TO REPLACED THE ACCUMULATOR OR ORIFICE TUBE IF EQUIPPED.IF OLD COMPRESSOR DIDNT LOCK UP.PUT NEW REFRIGERANT OIL IN COMPRESSOR IT TAKE AT LEAST 1 OUNCE OF OIL BUT CHECK OWNERS MANUAL ALL VECHICLE HAS DIFFERENT SPECS.AFTER COMPRESSOR OIL BEEN PUT IN EVERYTHING ALL REFRIGERANT LINES TIGHT.TAKE VECHICLE TO A GARAGE THAT DO AIR CONDITIONER WORK.THEY HAVE TO USE A VACUUM PUMP TO PUMP DOWN THE AC SYSTEM TO REMOVE MOISTURE AND LEAK TEST THE SYSTEM WHILE IT PUMP DOWN.IF YOU DONT LET THE GARAGE PUMP DOWN SYSTEM. THE MOISTURE WILL FREEZE UP IN AC SYSTEM CAUSING POOR OR NO COOLING.THE GARAGE GOING TO CHARGE YOU TO PUMP DOWN AND CHARGE UP SYSTEM.IT WOULD BE CHEAPER TO DO THIS THAN TO BUY A VACUUM PUMP AND MANIFOLD GAUGE SET.WHEN DOING AC WORK YOU NEED SPECIAL EQUIPMENT AND TOOLS TO DO THE JOB OR THE AC SYSTEM WILL NOT WORK RIGHT.

Ok if you want to do a home repair in hopes of saving yourself a lot of money and with hopes your system is not in major trouble, here goes:
First step buy 3 types of 1 lb. cans of refrigerant R134a at a parts store, 1 can of leak detector freon combination, and if possible 1 can freon/air conditioning oil combination freon along with 1 can of straight r134a freon.
The store will sell you a charge hose with a cheap type of charge gauge attachment and fittings to attach to your system for the re-charge.
Providing your system is low on freon,First, with the vehicle running and the a/c on full cold, high fan, install the 1 lb. can of freon/oil combo first only charging through the low pressure side of the system never through the thin line high pressure side as the pressure from the high side can enter the cgharging freon can and explode it like a bomb,(this low side line is the larger hose and the low side charging hose fitting the parts store sells you will only screw onto the low side charge valve which is normally marked "low" on the top of the plastic dust cap that is factory installed(hand screwed) on the low side valve fitting.
Secondly after the oil/combo can is emptied into the low side and you of course are wearing mechanics hand protection gloves and eye protection googles, then and only then will you install the leak dector 1 lb. freon can combo.
Third you will install the last 1 lb can of r134a freon, however your vehicle will not allow the whole last pound of freon into its system by means of a pressure relief blow valve that will automatically blow off any excess pressure once the system over fills, the system typically holds approximately 2.75 lbs. of freon.
If you have successfully installed the above freon into the system it should be up and running providing the system is in fairly good working order, by that I mean it may have a very slow leak that allowed the freon tio originally escape in the first place causing you to refill it, and if it does have a leak the leak detector die that you installed into the system should leak out from wherever it may be escaping from, indicating the place of needed repair by means of a red or blue, or whatever other designated coloration the die gives out from the leaking area.
Please note: Not all home charging techniques typically work as there are many mechanical failure factors in an a/c system that may require a certified a/c technician to determine exactly why your system is not working should the home remedy fail.
I hope this helps you and remember to always work safe with eye and hand protection especially around freon gases which become extremely cold and can cause frost bite when contacting with the bare skin.

the charge may have leaked off and now leak diagnostic may be in order...start looking for oil/wet spots within the system which may be freon oil hence freon loss

well first question is
1. does it have a leak in the system?
2. was the system open for any leanth of time?
3. did the compressor lock up causing the system to fail?
4. if the compressor did fail, then the system will require a rebuild....compoints replaced and flushing of the no replaced parts.

if you answered no to thies questions then

if the system is empty....

1. to properly charge a system it need to have a vacum drawn on it to 30lb for min of 15 mins.
2. then there ststem ( depending on the last service it receved or miles on the system) i might require sever ounces of pag oil
3. once these requirements are met, the proper amount of 134a need to be charged to the system.
this is done thru a scale or other mesurement device....just adding cans of 134 will not work properly ( back in the age of R12 a system could be severl ounces off and still work properly, 134 require an almost exact amount to work )
4. once the system is charged,,,cycle the a/c on and off severl times to flow the pag oil into the system.
this should do the trick. but it require specility tools.

if the system is low ( only from a leak in the system some where)
you MIGHT try the auto parts answer to a/c charging and place a do it your self charge up kit to it....
1.it will have a guge and proper attachments....
2.follow the directions and hope for the best...... but again.,...this might buy you a little time....
3. a problem still is with the system and will run low again causing it to shut down due to lack of proper presures.......

with people hunting to fix what they have try a local reputable A/C / Radatior shop with the proper equipement....but ask for prices and if there are any deals to be had....a smart shoper is always better then a poor consumer...... i hope i helped...good luck :)
