Question about 1992 Honda Civic

1992 honda civic lx a/c will not work when weather is too hot

I live in Florida, and when the weather is too hot outside in the afternoon, the A/C will not work, it works in the morning and evenings.
I try to play with the A/C button and sometimes the A/C will come on.
We changed the entire A/C compressor last year because the old one was doing the same.

Any idea?
I live in Northern California and my 92 Civic does the same thing. As soon as the weather gets uncomfortably hot the A/C is random at best, sometimes playing with the buttons makes it work but once it goes about about 95F it basically doesn't work at all. You've had it charged but that didn't help?

Hi, if the temperature is above 95, this is past the threshold of many AC unit that are using the newer form of refrigerant that is configured for low Ozone depletion deposits. the threshold for most AC units is 98 degrees F and, if the temp is higher than 98 or, just above 95, it will seem like the system is not preforming as it would if the temp was below the threshold(95-98).

This is a no user fault situation and you car is fine. its just the extreme temperatures that will cause the system to overdrive the compressor beyond the threshold. you can combat this issue by purchasing a higher grade refrigerant for your local auto parts store like Auto Zone or O riely's. These alternative refrigerant i speak of are good for areas of the nation that experience higher than normal temps in the summer months.

i would also recommend outfitting the vehicle with a larger AC refrigerant cylinder and booster. this will increase the capacity of your AC and the AC booster will increase the compression, in return, allowing for a colder temperature output form the AC vents. this will help during these grueling summer months.

You can find these parts at look for an AC booster and a 30lb AC refrigerant cyclinder. all this can be ordered online or you can pick it up at your local auto parts store. you will love the booster.

    Hi again. Just to make sure of the AC button switches operational value, i recommend checking this buttons connections. make sure that this button is connected properly and the wires are not lose or worn. replace the switch if necessary and remember to add a high capacity refrigerant cylinder and a AC booster as well. this will Boost your cooling system dramatically.

My car likes to start in the. Morning but not in the afternoon and especially not when it's hot . I have changed my spark plugs and my fuel lines and it still does it what could it be .

Most Honda cars have a problem with the fuel pump relay where it works cold but not hot.
You need to know if you are lacking spark to the plugs or fuel pressure when it fails to start. If fuel pressure is the problem, check the relay.

1992 honda civic lx a/c will not work when weather is too hot

I had the same problem with my 1992 Civic.
After an exhaustive search on the internet, I found that a few others had been battling this problem also. Mine went on for a couple of summers before I finally got serious enough to find it.
It seems that some of the solder joints in the Heater Control Assembly were a bit weak and although the A/C light may come on and go off when you press the button on your Heater Control Assembly, the switching never actually occurs. This is because there are another four solder joints for this switch alone. That's right, if my memory is correct, there are a total of six solder joints for that A/C switch, located inside the Heater Control Assembly.
When the weather is cool, the solder joints seem to be OK, but when things get hot, the metals expand, and you will lose the connection.
It's quite a lot of work to remove the Heater Control Assembly, and you need to be careful pulling apart the unit once out of the car, but if you're mechanically inclined, it can be done for just the price of a little solder.
If you don't trust yourself with pulling apart the assembly and resoldering the connections, you can also replace the assembly. I found it listed on-line at Majestic Honda for about $240.
I hope this helps.
Good-luck, Mark

i agree to both solutions the problem on these vehicles are due to a bad fuel pump relay which is mounted right in the steering columnway inside the dash board it consist of seven wires and the relay takes a long time to cool off and causes this problem replace the relay the last time i bought one was around 110 dollars and it is best to get one from HOnda
