Ac works fine and sometimes clutch disingugesa and blows hot air


This is usually caused be low Freon in the system. There is a low limit switch and when the pressure drops the switch opens the compressor stops.

1994 chevy 1500 ac compresssor stopped working fuse is good


couple of reasons
there is no gas in the system and the low pressure switch has stopped the ac compressor
there is too much gas in the system and the high pressure switch has stopped the compressor
there is a blockage in the tx valve and the high pressure switch has stopped the compressor
The climate control module has failed and stopped the compressor
I am thinking a leak and no gas.

V09a1aa4ak oil capacity


There is no need to add oil to an ac compressor unless you have had a massive leak. new compressors come with the right amount of oil. The compressor oil circulates with the gas and by the time the gas pressure drops from a leak then the amount of oil leaked out is just a few drops. Excessive oil in the system stops the TX valve from working and causes problems . If still in doubt then talk to an accredited ac specialist

Ac compressor cycling with no cool air blowing inside


Depending on how much freon is in the system, it could be a faulty low pressure switch or a faulty clutch.
You would jumper the low pressure switch to eliminate it for a test.

2000 dodge durango, a/c compressor stopped working after freon was added, did I do something wrong?


at a rough guess you add excessive amounts of freon and that caused the compressor to seize up
gas is added using pressure gauges and not by the can
besides that did you use the correct gas as the r134a runs at a much higher pressure and will deliver liquid back to the compressor which is not good for the operation

Ac was running when driving to the store, stopped to gas car then on the way out turned on ac no air coming out and the ac light does not turn on. i checked the fuses all are working but no power running...


Most likely the AC compressor clutch isn't engaged. This happens when the refrigerant pressure switch doesn't detect pressure in the coolant lines. The cause is usually a refrigerant leak.

This way the AC compressor is protected from running dry and possible damage.

Let your local repairshop check AC line pressure - if no pressure, look for the leak first then refill with fresh refrigerant.

1995 cirrus lx 2.5 a/c wont engage. freon full, fuse curcuit good, jumped accross the circut and it works. throwing code out saying open switch if it is somthing real serious,can i jump it and leave...


Jumping the switch is only recommended for very short periods of time to check the compressor itself. The problem with straight-wiring it is that the compressor will run all of the time. During normal operation, the compressor cycles on and off depending on the pressure inside the A/C system. If you run the compressor all of the time, you run a risk of causing substantial damage to your A/C system, your car, or even yourself. The compressor would be constantly pressurizing the system until something releases that pressure. It may be an A/C hose or it may cause something larger to explode under the tremendous pressure. Be very careful with the A/C system and get the advice of a licensed A/C technician.

How do you add the 134a to a 1997 chevrolet lumina?


Go to wal mart $6.00 a 12 oz can,may need 2 cans. Car owners manual will tell capacity in oz of AC system never charge over that amount into your system, also PSI and ounces are not the same thing

Go to auto parts store buy R-134a charging hose kit with a gage built in.$ 10.00

Turn engine OFF Under the engine hood, is a large aluminum cannister usually on passengers side ,on it or on a hose coming out of it will be a black plastic cap,with a connect fitting under, remove cap, pull and hold back the locking ring on the charging connector and push on fitting. look at gage it will show how much freon pressure is in system, with engine and ac off a higher pressure value will be on gage Start engine and turn ac on cooldest and fan high. The pressure will drop. if the pressure drops below about 22 PSI the ac compressor will stop automatic by the low pressure cut out switch.then the pressure will build above 25 and the compressor will engage again, this is short cycling(no/off) on the low pressure sensor and is a good indicator of a low charge of refigerant(R-134a). Charge according to instructions on kit. When the pressure stays above 28 and the compressor stops cycling off your good DO NOT over charge or you can cause compressor slugging. Liquid into compressor($1200.00 for new compressor)
SAFETY!!!!
R-134a can cause blindness. wear goggles and gloves

The "O" ring seals in the ac system dry out when the ac is not in use for over a month and leak the refigerant out again, So Use your defrost setting in the winter because it runs the ac compressor for dehumidifying, but only after the engine has warmed up a little, or with no warmth from engine the defrost will blow freezing air.

AC does not work


check the psi level on the system, cause you may have a leak and the system dropped the pressure level, if the level is fine then replace the compressor, cause it it probably bad... hope this helps you...
