There is an idle speed control motor on the side of the car's throttle body that is supposed to keep the idle stable even when additional loads like the AC are on. It's possible the motor may be damaged due to a voltage spike when you had it jumped. It's also possible the AC system may be pulling the engine speed down due to an internal problem with a faulty AC compressor.
Did the shop that checked the charging system check to make sure alternator was charging properly with the additional loads of the AC, headlights and blower motor on? It's very possible the system is overloading a weak alternator.

Typically, AC will not work because of a low charge. You can prove or disporve by jumping the low pressure warning switch. If the AC runs when you jump it, you have a low charge. If it will not run when you jump it, you have other troubles.

Freon is dangerous. Please dont try to charge your AC yourself.

Thank you for your interest in FixYa.com

you can check the ignition switch but for such a young car its pretty unlikely. If its not the ignition switch then you have an electrical wiring issue and those are typically very complex.

NOPE STOP CHARGING DONT PUT NO MORE REFRIGERANT IN SYSTEM.DO GOING TO DAMAGE NEW COMPRESSOR AND THE EXCESS PRESSURE WILL BUILD UP CAUSE THE REFRIGERANT CANISTER TO BURST EXPLODE INJURY OR FATALLY HURT YOU. BEST TAKE CAR TO A GARAGE.LET GARAGE PUMP DOWN AC SYSTEM AND CHARGE UP.BECAUSE YOU WILL DAMAGE NEW COMPRESSOR. MOST OF TIME I WILL HOT WIRE THE AC COMPRESSOR. MAKE SURE COMPRESSOR HAS 2 OUNCES OIL IN IT.IF COMPRESSOR START UP NO OIL IT WILL LOCK UP.DONT KEEP PUTTING REFRIGERANT IN THE AC SYSTEM, THE R 134A GOING TO FREEZE UP TOO MUCH MOISTURE IN SYSTEM YOU HAVE TO HAVE A VACUUM PUMP TO PUMP DOWN AC SYSTEM CHECK FOR LEAKS BEFORE CHARGING SYSTEM UP.LOW SIDE NEED TO BE 31 - 36 PSI THE HIGH SIDE SHOULD BE 165 - 205 PSI.

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.

how do i fix my ac/ heater they both wont work not even defrost it use to work only on selection number 5 now it dont work at all we just put a new blower in it today and it still wont come on

the control module is bad it has an intermittant fault replace this and it will work fine

What you can do is get your self a refrigerant from Wallmart about $7.00 and charge it, in compressor it self it tells you what kind of refrigerant is require for your compressor. follw instruction that comes with the refrigerant on how to charge it.
AC is running and setting in maximum while charging and dont overcharge.
As soon as you start chrging the compressor should start running when the pressure build up.

Check the MAP sensor connection/connector and either the seal where it plugs in the intake or vacuum hose connection .
