Question about 1992 Honda Accord

1 Answer

Air conditioning not cooling properly

I have a 92 honda accord & the ac isnt cooling properly. I have replaced the expansion valve and the reciever/dryer. Blow the lines out. Pulled a vacuum on it, charged it and it still doesn't cool properly. With the ac on max, it cools decent at idle but when you pickup the rpm's it pulls the low end pressure way down and cuts the compressor off. Then the compressor turns off and on during driven. All repairs were with a friend who is an ASE certified machinic and we are stumped. Before we change the compressor we are seeking as much advice as possible. The system is 134a now. Thanks

It sure sounds like a restriction, but you seem to have covered most all the bases I would (I am a ASE Master technician) see if the fixed orifice is plugged or restricted??, maybe the system is freezing up, is the compressor cycling switch set correctly to approx 28-32 psi??

02 HONDA ACCORD AC COMPRESSOR ONYL COMES ON ON ACCLERATION


This problem can be caused from a malfunctioning expansion valve. This valve is what meters the amount of refrigerant that enters the evaporator as a gas. If this valve fails to go the proper position for refrigerant line temperature, it doesn't convert the refrigerant into a gas, but instead it remains a liquid, and the cooling effect stops. You need to take it to an AC shop so they can check and see if the expansion valve is working properly.

Where is the expansion valve on a 92 honda accord lx 2.2


Shouldn't have an expansion valve. There should be an orifice tobe in the refrigeration line before it enters evaporator usually near firewall. Just my opinion.

I have a 92 model honda accord the car is boiling water but the temperature indicator remain normal


Be sure your radiator/cooling system is full. In many cases there is a bleeder valve to release air. If there is none, 'bleed' air at top radiator hose. Remember, this system is under pressure, you can burn yourself badly if U dont follow proper procedure. Look it up in your repair manual.

Location of expansion valve


Expansion valve is located passenger dash area , inside the evaporator housing. This is not a repair that can be easily done by a home "do it yourselfer".It requires evacuating the the air condition system of freon is the biggest obsticle doing at home. Rec. taking to a certified a/c repair shop for this repair.

You need to discharge the AC system and remove the evaporator to replace the expansion valve. No two way about it.

No need to remove the dash

Replace expansion valve


Hi Tresap,
The only expansion valve that I can think of that you may like to replace is on the air conditioning unit....This valve is found usualy mounted onto the AC unit....You'll have to remove the dash board and centre consul....This is qute a job....You should then see the expantion valve on the cabin side of the AC housing....where the pipes go thru into the engine compartment....NOW HOLD EVERYTHING.....before you can remove the valve you need to depressurize the AC unit....That should be done by an expert....The gas is dangerous and you must wear safety googles at ALL times....Once you have removed the valve, you must seal the system so that as little moisture as possible enters the system....If it is left open, you'll have to replace the dryer unit too....when you've finished your replacement, assembly is the opposite as disassembly.....You'll then need to have the system recharged....Don't try to engage it until that has been done....It wont work even if you tried ,as there are pressur switches which will inhibit the opperation....If you have had practice, it will take about three quarters of a day......if not, three or four days

Hope that this helps you

Best regards Johngee10
