What else could be wrong with the air conditioning system that won't blow cold air when the compressor has recently been replaced?
How much freon does a 1992 Lincoln Town Car take after the compressor is replaced when it does not say on the compressor?
Everytime you run your 99 cavilier with the air conditioning on it blows out cool air but when you stop It blows out hot air like it stops working?

Asked in Cars & Vehicles, Cadillac DeVille
Why will the AC not come on in a 1996 Cadillac Deville replaced the compressor the accumulator and the orafice the compressor is fully charged with freon?
Redoing an AC system is trick business, the system must first be evacuated by a vacuum pump to remove all air before the refrigerant can go in and the pressure switch will not allow the compressor to come on or it will short cycle. Assuming you did it all properly try disconnecting the wire to the compressor and jumping it to 12 volts, that will activate the clutch. If it comes on and blows cold then the switch inside the car might be bad or some other electrical issue such as relay or fuse is the problem.
Asked in GMC Savana
How do you know if bad compression or a low pressure switch is causing the compressor in a 1999 GMC Savana not to kick on and the drier orfice and compressor have been replaced?
If you replaced your compressor less than 90 days ago and the unit doesn't work again if the entire unit is replaced can you reuse the compressor or return it?
Why wouldn't the AC compressor turn?
The most likely reason the compressor is not coming on is because you are low on freon. The low pressure switch will keep the compressor from cycling on because damage to your compressor would result. You can jumper across the low presure switch with the engine running and A/C turned on, ( for short time only) this will provide you with question is my compressor clutch good, or am I just low on freon. The AC compressor relay switch may need to be replaced
1994 GMC sub Ac compressor clutch disengages if you open the hood and tap on the plate it engages I replaced the clutch coil assembly and the new one does the same thing HELP JR?
Maybe a bad or loose wire on the compressor? Check the wiring real good for loose or dirty connections. Look for any cracks or breaks too. It's also possible that it's just a little low on coolant and it's a coincidence that you opened the hood and the compressor disengaged. Check the connection to the low pressure sensor and make sure you have enough refrigerant.
Asked in Air Conditioning and Coolant
I installed a new AC compressor. I do not have freon in the new compressor and it is not hooked up. My question is... will it hurt the vehicle if I drive with out hooking up the AC?
No harm will come from driving it. You just don't want to use the AC system without any refrigerant in it - that could harm the compressor. The refrigerant also cycles the compressor oil, so running the compressor without the refrigerant in it is detrimental in this regard. Also, since you had to open up your AC system to replace the compressor, you should have also replaced either the receiver-drier or the accumulator (your vehicle will be equipped with one or the other, depending on whether you have a Thermal Expansion Valve system or Fixed Orifice Tube system - it'll never have both), as they contain a desiccant which will become fully saturated within five minutes of exposure to atmospheric air. The desiccant in these components is vital to the proper operation of the AC system.

Lumina 2003 ac not cooling even when compressor is replaced?
How do you replace AC compressor bearing without removing the compressor on a 1998 chevy Silverado?
Doesn't matter - if you open up the compressor, you open up the AC system. By law, this must be done by an ASE certified technician in an EPA approved shop with the proper equipment to evacuate and store the refrigerant. This prevents refrigerant from being released into the atmosphere. Whenever the AC system is opened up, the receiver-drier (if it's a Thermal Expansion Valve system) or accumulator (if it's a Fixed Orifice Tube system) must also be replaced.
What is the cost of repairing car air conditioning compressor?
first off you need to determine that i s the cause of your problem,, could be the clutch, hi lo switch, temperature control unit, or broken wire or fuse, if you determine the compressor internally destructed, the entire system refrigerant side is toast, everything along with the compressor needs replaced, plus add a high side filter, new receiver drier, orfice tube evaporator, condenser,and clean out the hoses unless it has a muffler, then they require it be replaced

AC compressor - clutch seems to be locking upmaking noise can only the clutch be replaced or does the entire Compressor need to be replaced?
If the AC pulley is locking up when the ac compressor clutch engages, it's not a clutch problem, it's a compressor problem. But yes, the AC clutch can usually be replaced separately. The problem is, if the clutch is worn out the compressor is probably worn out as well. It usually isn't that much more to replace the whole thing.

How can you fix your ac compressor on your 1991 Ford Taurus SHO?
AC compressors are relatively easy to replace, typically it's only the serpentine belt and a few bolts. The hoses are a little more trouble. Typically a worn or failed compressor has deposited debris in the refrigerant lines requiring that they be replaced or cleaned. The procedure is: 1, extract any remaining refrigerant from the system into an approved container suitable for recycling. 2, remove the serpentine belt, disconnect the refrigerant lines from the compressor then remove the bolts and lift out the compressor. 3, Examine the inside of the refrigerant lines, looking for any discoloration. If the remaining oil is not clear, you should flush all of the refrigerant lines to make sure they are completely clean. Since you'll be replacing the old R12 refrigerant with 134A, you should probably do that anyway. 4, Since the vehicle is "experienced", it would probably be a good idea to replace any of the rubber refrigerant lines. That way you can avoid some problems. Since they are that old they'll be leaking soon anyway so you're not really wasting money. 5, Replace the receiver/dryer. 6, connect the new compressor and refrigerant hoses. 7, Connect the serpentine belt. 8, evacuate the system. If you don't have an evacuation pump for air conditioners, have someone do that part for you. You need to verify that there are no leaks anywhere in the system BEFORE you put the oil charge or the refrigerant. Air conditioning compressors are not repairable by the home mechanic. Unfortunately your only option is to replace it.
