I just recently flushed the ac gas of my 2003 accord and refilled it with 2 cannisters of 134a gas. I noticed that the passenger's side cools better than the drivers side. could it be a problem with the climate control switch or that the gas is insufficient.

Make sure your blower fan is turned on and is blowing air. When you push your a/c button the yellow light should come on. If it is not blowing cool, it could be several things. Low on 134a or the control that has the a/c button on it could be bad or blown fuse, bad compressor, etc. If the air is cool but not cold the 134A is low. If it is still blowing hot, check and make sure that the clutch on the compressor is locked in. It most likely is not. Check ac fuses and ac relay, if they are good, check the 134a ,if low, refill it. This should fix it. Remember that if the a/c clutch is not locking in, you cannot add 134a because of no circulation.On some vehicles, if it is completely out of 134a, the relay will not trip and you will have to bypass the relay to provide power to the compressor to fill it. If you do all of these and it still does not work, you will need to take it to a professional. If you need to, reply back and I will give you more possibilities.(I think that you mean evaporator coil)
when you replace new compressor/you shoud have to flush ACsystemby usingR11 AND needto replase expantion valve .after that you need to vaccuming AC system.also put AC compessor oil and refill 134A gas.
Most likely low on refridgerant. ports are difficult to access .In front of passenger front wheel the accumulator is located. low pressure port is on top of it. Try and add a pound of 134a and see if it cools more efficiently. evaporators are common source of leak on these fine machines.
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)
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.
First, the old R-12 must be completely evacuated fromt the system. R-12 and R-134A do not mix and won't function together. Once you are sure there's no R-12 left in the system, you need to install an R-134A fill valve on the low side AC line. This is where your refill hose will connect to add R-134A. Once the valve is in place you're ready to fill the system. The compressor requires a minimum of 20psi to engage and should not be filled to more than 45psi.
RECHARGING AC SYSTEM
1.Turn the truck on and turn AC on HIGH 2.Locate the low side AC line (will have a valve and cap similar to the cap on a tire) 3.Insert the oil or R-134A can to the hose (Do not turn the screw to puncture the can yet) 4.Insert the other end of the refill hose to the low side valve 5.Puncture the R-134A can with the screw on the refill hose 6.You should feel the system suction the refrigerant out of the can 7.Check for frost on the AC lines and the air blowing inside the truck 8.If frost develops and the air is cold, you've successfully recharged the system and disconnect the refill hose. DO NOT ADD MORE REFRIGERANT...overcharging the system will damage your compressor and will be less effective Hopefully this answers your question and you're able to get your AC working again. Best of luck.
I ad this problem fixed and it cost $35. Apparently, this happens when the Freon level is low for some reason. They refilled the Freon and now I have AC on both sides. Don't forget to replace the internal filter in the glove box.
yes you can flush out the coolant system, also you might need to recharge the AC system by using the Refergerint R-134A (which you can buy at autozone or other auto part stores) and charge the 134A on the Low side port.
