Question: Is fitting leaking at the compressor or at the rubber hose end.

If leaking at the compressor hard line fitting. Try replacing "o"ring.
If leaking at the rubber hose end. Remove line and take to a HVAC shop that can replace "barrier hose (rubber hose using your fittings)

Any repair will require discharging the system.

I have a 94 tracker with hoses leaking. I would recommend replacing the rubber hose sections on both suction and liquid lines at the same time. You will have to discharge the system for either repair.
I would also recommend replacing all "o" rings accessible at this time along with a receiver dryer.

I work in the Auto parts sales for a large after market parts supply company and have found that hoses are not available from anybody, including a dealer for my 94 tracker. The system is very expensive to repair if you can find parts.

Hope this will help.

i have 2 questions.
1: is the compressor shaft dropping dead, ? when A/C on?
the shaft actual not the clutch , pulley, its spins near engine speed.
2: no for above , did you check the low side pressure, what is it?

3: pressure is good, is the hi/lo switch open?

4: no, good and good. so we arrive at the AC AMP.
did you check the voltage on all pins.
the AMP drops the AC clutch for up to 6 good reasons.
saving driver from loss of engine power and for protecting the loop reasons.

You need to check the freon level and if that is good check the compressor. If you have no pressure on the low side, when I say pressure on low side I mean vacuum, then most likely the compressor is bad or you have a leak someplace. You can get a freon fill kit at Walmart, Target, Auto Zone and most any auto parts stores. These kits comes with a gauge and connection hose. Typically if the freon is low the compressor won't activate. Connect the fill hose to the low Side of your AC and turn the AC on to Maximum with the engine running. If its a low freon problem the compressor will start to kick in as the pressure increases. Make sure you don't overfill the system as this will cause a seal or line to blow. Being a 1998 your vehicle should use R134A freon which is what can legally be purchased by a home mechanic. It cost about $12 to $20 a can and usually includes a leak detector additive and seal conditioner.

How is the best way to recharge freon in the ferrari 328.? any common point of freon leakage?


All vehicles will leak a miniscule amount of freon from the seals throughout the coolant lines, you can use a leak detector additive when adding freon or use a freon gas leak detector to find any substantial leaks in the system by guiding the probe around all the components while the vehicle and ac are running. You could use a heldheld freon charger with a built in pressure guage provided you have the correct fittings, otherwise I'd recommend having both your low/high pressure sides monitored while adding freon and making sure your compressor is turning on and off properly as the high pressure side reaches its peak.

My ac wont get cool.......it blows hot air and(caddy seville 95)


Below is a guide to troubleshoot and check system function. This can be done by most folks.

Look at the front of the ac compressor and have someone turn on the ac from inside the car. The front of the pulley(clutch) will spin when turned on.

If it does not spin, the low pressure switch (LPS) is not satisfied. Meaning there is not enough freon in the system to operate the system. Means low freon capicity because of a leak.

The LPS can be jumpered to cause the compressor to run (clutch to engaged) which will draw the freon in the system.

The LPS is usually a two wire sensor on the suction of the compressor. (between evaporator and compressor) Unplug the sensor and install a jumper, this will engage the clutch. Connect a new can of freon
and fill to system capacity.

The capacity of the ac system will be on a label under the hood, do not overfill. Probably about 2 lbs. Local parts stores (Auto Zone and Advance) will have freon with stop leak. This may help the leak. They also make a freon with a UV dye. I always add a single can with dye so that if stop leak does not work I can find the leak in the future.

The system should be filled until suction pressure is about 30 to 38 psi..

Remember the flow for the a/c system is :
1. From the compressor a high pressure (HP) gas goes to the condenser in front of the radiator.
2. From the condenser a HP liquid goes to an expansion device (orifice tube or expansion valve)
3. From expansion device the low pressure gas enters the firewall to the evaporator.
4. From evaporator the low pressure liquid/gas mixture goes through the dryer2_bing.gif back to the compressor suction.

I have a 1996 geo tracker I cant get the compressor to run I have relpaced the compressor relay which dosent help. freon is ok compressor cluch kicks in when direct wired.


does the compressor run when bypass the compressor thermal cutout switch on the compressor? here is the part number and a picture.
also does it run when u bypass/jump the compressor cycling switch? it is located in the low side of the sytem, thios is the line that is the larger of the two, hwere is the part # and picture.

How do you jump a/c compressor so it will take the freon?


The interuptions in compressor engagement is due to low side drops which is controlled by the pressure switch mounted on the low hose or large metal accumulator on the passenger side. Low side hoses are larger and the accumulator is on the passenger side engine compartment...a paper clip works fine jumping this low side pressure switch out until freon pressures increase enough to keep compressor running to accept freon.

Where does the freon go for a 99 expedition


Hi .. I just ran into the same problem .. I have a 2000 Expedition with the 5.4L engine .. the low side port is located on the passenger side of engine compartment just below the black metal bracket that contains electrical connections right in front of the firewall... you have to reach under this and locate the low side (larger line) and feel for the connection .. it is right in front of the accumulator .. There are two heater hose that hide the port .. you have reach under these to unscrew the port cap which is black .. you'll have to do this by feel .. I have found that you can by R134A charge with dye and leak sealant helps with small leaks .. if the system takes more than two cans be usre to add refrig. oil .. hope this helps

Where is the low pressure value located so i can add freon into the compressor


look at the ac compressor and follow the large ac line/hose untill u come to the service port,,has it been retofitted for 134a? if not go to parts store and ask for a retro fit foe the low side,u will need to remove the sharader valve before installing the low side retro fit,,also purchase a charge hose

To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI
Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI
Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better!  Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Both low and high side readings are lower than normal, this indicates a cars AC system is low on refrigerant and is under-charged.
If both low and high side readings are too high, this indicates an overcharged system - too much refrigerant. This also can indicate that the condenser fan is not working, is too slow or the car is overheating and heat is transferring from the radiator to the condenser.

Good luck and hope this helps, keep me posted be glad to answer any question you may have. And yes the A/C system on your car uses R143a and there is a A/C pressure switch along the low pressure line or on the accumulator, it looks like a oil pressure sensor with a two wire lead cliped on it.

A/C Compressor not kicking on


The power to run the compressor clutch coil goes from the battery, to the AC Clutch Relay, somewere in the engine compartment fuse box, then it goes to the positive side of the AC compressor clutch coil; goes thru the coil, activating the compressor, and then goes to complete the circuit through another switch (high pressure protection switch) in the back of the AC compressor and finally reaching negative or Ground.

Disconnect the AC compressor clutch connector and using a 12 V bulb with 2 wires (test lamp) check the following:

1.- connect 1 lamp wire to battery neg; with the other check both pins at connector with the AC in the RUN (AC and ignition switch on ) you should have power in one side.

2.- connect 1 lamp wire to battery positive and with the other check both pins at connector, lamp should light getting the ground from the clutch connector thru the high pressure compressor switch to ground.

On the other side what makes the relay close and let the power flow to the clutch works with the low pressure switch, (if the freon pressure is too low it opens and kills the ground to the relay coil and that kills the compressor), that low pressure switch is in the low pressure side of the freon tubing, the fat pipe that comes from inside the firewall into the accumulator/dryer, a big aluminum cylinder sitting on the right side of the engine compartment in GM cars.

To know if the low press switch is the cause you can unplug it and connect both legs with a paper clip for a minute or two, no more, you don't want to damage the compressor. anyway if jumping the switch makes the compressor come alive and kick in, you either have low freon pressure or a bad switch; it's time for the pressure gauges and check how the compressor is pumping and that is better left to a pro.

By the way you said that your system is a R-12 system, have you considered switching to R-134a the new "ozone friendly" freon? to do that you need to evacuate the system with a recycling machine and pull vacuum in your AC, if it holds the vacuum for a while, then you can be sure that there are not leaks and then dump 1.5 or 2 pound (check the labels in the engine compartment) of R-134a into your system. it will be a good idea to put some fluorescent leak detecting dye in the system to check for leaks, just in case..
