Re: Mustang Air Condition
Sounds like you have a freon leak somewhere. No gas or low gas in the system will not let the clutch kick in. Have it check out professionally, unless you know what you are doing in terms of low side and high side pressure check. The latter can be dangerous if you are not familiar with the procedure, if you connect the freon or the 134 can to the wrong nozzle, the can can blow up.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

THERE IS A FUSE,HOWEVER MORE COMMONLY YOUR SYSTEM IS LOW ON R12 AND CUTOFF SWITCH IS ACTIVATED. TRY JUMPING THE CONNECTOR OUT OF THE ACCUMLATOR,THERE SHOULD BE A SWITCH ON IT,PULL CONNECTOR AND WITH VEHICLE RUNNING GET A PIECE OF WIRE AND INSTALL THEM IN BOTH FEMALE TERMINALS. IF A/C CLUTCH ACTIVATES SYSTEM IS LOW OR BAD SWITCH OR BAD FIELD COIL OR CIRCUIT DAMAGED
sounds like the air-con gas is low switch on air-con a nd check to see if the compressor clutch is pulling in if not reove h/p dust cap on the aircon pipe press schroder valve to see if gas escapes if not will need re-gassing even if you get gas out without a pressure gauge it is hard to tell if the right anount of gas is in the system.
IS YOUR AC COMPRESSOR DOES NOT TURN ON YOUR MAY HAVE LOW FREON. THERE IS A PRESSURE SWITCH WHICH MUST HAVE A CERTAIN AMOUNT OF PRESSURE TO ENGAGE THE COMPRESSOR CLUTCH. CHECK FREON LEVEL ON THE LOW SIDE. AUTOZONE WILL SOMETIMES DO THIS FOR YOU OR YOU CAN BUY A GAUGE FOR ABOUT 20 DOLLARS. IF YOU HAVE SUFFICIENT PRESSURE POST BACK AND I WILL WALK YOU THROUGH TESTING
U may be low in Freon gas. When Freon is low there's low pressure switch that will prevent A/C compressor clutch from engaging to protect it from failure. So, first check Freon pressure & any leaks form lines & hoses fittings. Even if the fan is working, that doesn’t indicate proper compressor OP'S. Look at the compressor front side you'll see the clutch stationary while the AFT pulley moving.
Then put air-condition compressor switch to ON (Engage), You should see the clutch engage & start rotate, If NOT, this is very clear indication u r low in Freon. Regards; MAR
if the compressor is loose compression, normally it sounds noisy. then suction pressure is above normal and if you accelerate and maintains that high speed, let say 2000 rpm, the suction pressure goes down to the normal level and cools your air conditioning .
