SOURCE: I installed new compressor and accumulator and AC

I would suggest checking the condenser fan relay. I believe it is located under the hood up against the passenger side firewall

So I can just replace ac compressor an bypass heater core an ac should work for 1991 Lincoln Town car


If the compressor is the problem A/C should work. But I work with idiots. I replace the compressor, expansion valve and dryer. And clean the system out. They replaced the compressor. then the expansion valve. then did it again after they clean the lines out, Then again, because the dryer held to much metal from the compressor going bad. And yes, you can bypass the heater core. But if the blend door actuator is bad, it won't be cold.

Where is the expansion valve located on the 2004 KIA Sedona


Kia Sedona expansion FRONT valve located under dash, behind glove box, fan and coil. Evacuate freon first. Disconnect Freon lines from firewall., Lay right front seat back to flat horizontal position and lay on top or totally remove the seat for easier working access. Remove under dash cover, fan, glove box, coil housing, remove coil mounting bolts, remove old expansion valve. (Inspect old valve, if debris inside, blow out coil before installing new valve. If visible debris best to consider replacing REAR expansion valve and DRIER/FILTER in front of radiator too and blow out all lines and coils while servicing.) Use compressor oil to lubricate "O" rings on new FRONT or REAR expansion valve, install valve bolts, reinstall coil bolts to FRONT firewall or REAR frame, reconnect freon lines to firewall in engine compartment. Evacuate AC system, install freon (35 1/2 ounces, nominal 3 pounds), check system for leaks, check for proper operation, enjoy.

On my BMW 325XI Wagon, the ac is not cooling, the drier, expansion valve, compressor & ac control module have been replaced. Starts to cool as low as 65 degrees & then compressor shuts off.


sounds like unproper ac evacuation before charging the freon to your ac system. do a proper evacuetion to the system check the ac compressor oil charge the proper freon & amount check the vehicle tag for the amount of freon under the wood close to the radiator

I have installed a new accumulator, evaporator, condenser , expansion tube and compressor in my 1999 chevy monte carlo. i put 9 0zs. refrigerant oil between the compresser and the accumulator. i also...


Is the pressure detection switch engaged? It detects pressure in the cooling system. This switch shuts down the clutch to prevent the compressor to run when there's a leak.

Sometimes there's a looking glass on the expansion bottle showing tiny bubles. A large blob of air indicates too much air in the system. Pressure might not be enough to engage the switch when there's too much air left.

I need a diagram on how to remove a ac compressor on a 1996 lincoln mark VII


There's not really a diagram for the actual removal and installation. A good repair manual might list steps like these: First, your system needs to be purged of the freon. Next, unplug the AC clutch/pulley assembly at the front of the compressor. Remove the belt, then the AC lines on the compressor (usually in the back), then unbolt the AC from any mounting bracket(s) and remove. To avoid having to press on and off the clutch/pulley assembly you might want to make sure you're buying a complete compressor assembly. Read and follow those directions concerning oil for the compressor. After installing the new AC, reconnect the lines with new "O" rings. Most if not all compressor manufacturers will not honor any warranty unless you change out your orifice tube (also called an expansion valve) and accumulator (aka the dryer) at the same time. Recharge the system with the appropriate amount and type of freon, most likely R-134a.

I need to change the ac condensor is it hard to change out what do i have to do


This will apply to most automotive A/C systems. You have to remove the accumulator, the compressor and the orifice tube (expansion valve).
Flush ALL the lines with an A/C flushing agent.
Install the correct amount of refrigerant oil into each A/C component per the manufacturers specifications.
You have to install a new accumulator, orifice tube and compressor and necessay "O" rings and seals.
Evacuate the system using a vacuum pump.
Check for any LEAKS.
Recharge the A/C system with the correct amount of freon per the manufacturers specifications.

AC Wont charge after replacing components


whenever the ac system has been opened it should be hooked up to a vacuum pump designed to evacuate the ac system of any foreign debris and oil etc and after should be able to hold a vacuum to show that there are in fact no leaks then if all is ok at this point you can then charge your ac with the proper freon specified for you car when the pressure reaches satisfactory level the ac compressor will then cycle on you should not bypass the low pressure switch

AC system's lubrication amount?


The oil spec is PAG 150--68.00 ounces. General Motors issues Bulletin # 02-01-39-004B replacing PAG 150 oil with a lower viscocity oil. Thus, now indicates PAG 46 (P46D) oil for those vehicles.
There is a high pressure side and low pressure side to the system. The high vapor=compressor to the condensor. Low side vapor=compressor to evaporator. Your system will use R134a freon.

The A/C is a sealed system and when the compressor fails it circulates debris throughout the A/C system and contaminates it. Before replacing the compressor several other A/C parts have to be checked or changed.
Typically, the condenser should be flushed to remove any debris or contaminated compressor oil. Use approved flushing agents (aresol or liquid pour types), that evaporate quickly and don't leave any residue in the system. You will also need access to 'DRY' compressed air or nitrogen to push the flush through the system. Nitrogen (an inert gas), is best because it doesn't introduce moisture into the system. You need to do this a couple of times.
Accumulator or receiver drier should be replaced when you are replacing your A/C compressor. If don't replace your accumulator or drier you will probably void your compressor warranty. It's virtually mandintory to replace the orifice tube or expansion valve. The openings are usually about .050" and are quickly plugged. Be sure to clean all hose assemblies internally prior to installing your new compressor. Not doing this could contaminate your new compressor. Flush both ways until the flush agent exiting is clean, you will need to remove the hose assemblies to do this.
After you have cleaned, inspected and replaced all the parts, you connect the vacuum pump and remove the air from the system. Make sure it holds pressure. Then recharge the system with the proper freon and oil to the system specified levels.

No matter why you are replacing the A/C compressor there is a lot of other related work that has to be completed before you install the new compressor. Hope this helps, good luck.
