SOURCE: Where is the low pressure switch for my Honda Odyssey 2003 AC ?

The A/C pressure switch is located in the high pressure line (the skinny one) on the passenger side of the engine compartment just under the fuse/relay box. The switch has three functions: <28 psi, the switch opens to protect the compressor from lack of lubrication. >220 psi, the switch shifts the radiator and compressor fan to high speed. >455 psi, the switch opens to protect the compressor seals. Check to see if you have any powertrain DTC's first. A faulty engine coolant temp sensor can cause problems with the compressor clutch relay. If the radiator and compressor fan come on with the A/C on but the compressor clutch does not operate, check the compressor clutch relay. You can also obtain Heater control panel diagnostic trouble codes (DTC's) by turning the ignition switch on. Then turn fan switch off. Press recirc button to select recirc air. Press and hold recirc to turn off recirc air but this time continue to hold the button down until recirc light comes on for two seconds and then goes off. If there is any trouble, the recirc light will then blink a code (if no trouble, the light will remain off) 1 blink = problem in air mix control motor circuit. 2 blinks = a problem in mode control motor circuit. 3 blinks = a problem in evaporator temperature sensor circuit. (this one could be a factor in your case) Turn the ignition switch off to end the test.

SOURCE: A/C compressor clutch won't engage, system won't cool

Your system might be low on freon. Get a kit with a hose that has a gauge on it so you can see if you are in the "Good" range. The cycling switch won't close unless there is enough freon in the system. You can temorarily jumper the connector for the cycling switch to see if the compressor will come on. If it does, you are low on freon for sure. Do not let the compressor run for more than 15 - 30 seconds with it jumpered.
report back results.

SOURCE: I need to know how to jump the ac low pressure to get my ac compressor to come on.

If you look on the low pressure side of the AC system you will see a plug that is incorporated in to the line. It will have two wires leading to it. Remove the plastic clip that attaches the two wires to the sensor and use a short piece of wire to connect the two terminals in side the plug by putting the ends into the cap. This will bypass the low pressure sensor and allow the AC clutch to engage and begin to cycle again. Remember this low pressure switch is there for a reason. If you don't add more r-134 to the system and allow the AC compressor to cycle you will destroy the compressor. You need to charge the system when you bypass the low pressure switch and get the system up to full charge status and reconnect the switch.

Can youput to much freon in and what will it do


4 cans will be too much
it makes the compressor pump liquid instead of gas and that damages the compressor
it the compressor is still capable of pumping gas then it will go to high head pressures and that will switch the compressor off
you have wasted your money, run the risk of expensive compressor damage , didn't fix the leak that required the gas
The specialist ac shops are not there to take your money but to give you a system that runs without problems so use them to fix the faults and put the right amount of gas in using gauges not cans

Either connection is bad to low pressure sensor or pressure sensor is faulty.

the best suggestion is to give up on replacing compressor clutches and have the system done by an accredited ac specialist shop
excessive pressure from excessive gas is hydraulicing the compressor and making the clutch slip burning it out
next flushing the system removes all of the compressor oil in the system leaving the compressor running virtually dry
next when a system is opened , moisture laden air gets in and that has to be vacuumed out for a period of 2 hours minimum or the water in the air turns to ice and blocks the tx valve
freon gas ( if that the gas that is supposed to be used as many now run r134a) is inserted ,not by the can but by the low pressure and high pressure readings on a manifold gauge designed for that purpose
I would say that by now you would have spent more money than what it would have cost you at the ac specialist shop

I have a 2002 Mitsubishi eclipse my ac pressure low side is 10psi but compressor is still running. I thought below 20psi the pump shuts off. Am I wrong??


WILL FIRST YOU NEED TO SEE WHAT YOUR HIGH SIDE PRESSURE READINGS ARE ,COMPRESSOR MAY STILL CYCLE BUT FAST OFF AND ON DUE TO LOW FREON LEVEL,BUT IT STAYS RUNNING ALL THE TIME MAY HAVE FAULTY COMPRESSOR ,READ VALVES IN COMPRESSOR BAD ,BUT REC CKING HIGH PRESSURE FIRST,HOPE IT HELPS

Ac compressor good but wont start


You must have a leak, the compressor will not run if the system is low on charge, the charge carries the oil to lube the parts of the system. Also do an electrical jumper of the compressor cycling/pressure sensing switch.

Ac not working 1996 jeep cherokee country.doesn't put out cold air


You could be low an R134a coolant, compressor might not be working or the pressure sensor might not be working. First thing you need to do is check the compressor look at the front of it and see if the center is spinning when you turn on the air, it should spin when the air is on or the defroster is on, if it is not spinning the R134a may be low or the pressure sensor could be bad. If it is spinning it may just be low on R134a but not low enough for the sensor to shut off the pump.Ok here is how to check if the compressor is (not spinning) Follow the aluminum lines off the AC compressor under the hood until you find the pressure sensor it will have a plug with two wires coming off of it, unplug it and get a 2 or three inch piece of wire like speaker wire or something that has a bunch of small wires in it and not a big solid single wire, strip both ends of the wire and insert them into the plug holes of the switch plug this should engage the compressor if not the compressor may be bad if so let the compressor run for a little while if the ac gets cold the pressure sensor is bad if not it the system is low on R134a which you can get from Wal-mart and do your self. If it does work with the wire and you determine that it is just the sensor you can run it with the wire in it but if the system ever gets low on R134a the pump will not shut off and it can burn out the pump so it is not recommended although i've been running mine like that for about a year now. Please post any further Questions.

No a/c not cooling at all it does cycle on and off the compressor turns on and off just charged has dual heating and cooling controls blend door sounds like it is working but only after you turn it off...


Compressor may be worn, unable to generate enough pressure to cool effectively. Could also be clogged expansion valve. If compressor checks out OK on high and low side pressure gauges, moisture in AC system is likely cause. Replacement of accumulator/receiver-dryer and vacuum purging prior to recharging system would correct this. It sounds like the air door actuator may also be faulty, or the HVAC computer may be malfunctioning do to pressure and thermal sensors registering a fault.

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.

AC compressor clutch is cutting on and off steadily during compressor operation.Is this clutch or clutch coil?I was pushing buttons on electronic climate control,and suddenly AC stopped working,only have...


You have to start by testing the pressure in the system. If it was cycling a lot and then quit it sounds like you developed a leak somewhere and once it fell below the low pressure switch it will not come on.

The system works with a high and low pressure switch that will cut out if the pressure is too high or low. When the system looses pressure it will fall below the low while running, turning off the compressor, When the compressor is off the high side and low side equalize out bringing the stationary pressure above the low limit, turning the system on again. This cycle will repeat until there is not enough pressure when equalized to turn the system back on.

If the pressure is good, go next to the relay, it should be located on the fire wall. if the relay is right, then you need to determine if it is high or low pressure switch shutting it off. IF it is the high, you probably have a restriction in the system, You could also have a problem with the compressor. With the car not running manually turn the clutch and see how much play, smell the area and smell if there is a burnt odor, then try to turn the armature that goes into the compressor. see if it is frozen.
