help ac only works when it wants to

[swizz977]

when my ac doesnt work everything lights up the fan blows but when i look under the hood at the thing that is saposto spin all the way to the right.. it doesnt spin.. but when my ac does work for the other half of the time it works fine and get cold.. please help its a 92 civic

ok so today my ac wasnt workin and i switched the relays around and it still wasnt workin.. then i swithed them around again and it started working

well there is 2 relays one for the clutch and another one next to it.. i switched them and nothing happend same s**t.. it just works really randomly.. it usto only not work rarely but now it just got a lot worse.. i dont think its the relay because it wasnt working and then i swithed them around cuz theres 2 for somthing else a fan i think or somthing and it was the same thing

the condenser fan spins when i hit the ac button and stops spinning when i turn the ac off so it cant be a hvac problem i think..

It sounds to me like you've got a relay going bad. Swap out the relays for ones you know work, you can get them fairly cheap online. Do both, because if one is going the other won't be far behind.

[edit]
The two relays your looking at are for the compressor clutch and the condenser fan, so they are BOTH necessary for your a/c. If one isn't working it can cause problems with the other.

or maybe check to make sure you have proper pressure ratings in the system

i just pressed the ac button and the condenser fan was not spinning..

i switched the relays around and it still wasnt spinning..

then i switched the relays back and it wasnt spinning

then i pushed the ac button off and then on and it started spinngin..

i pushed it off and on and it stopped spinning

did you check your charge pressure? if your charges arent correct the compressor wont stay on or come on, also you may need to change your expansion valve and dryer

try buying a new relay. every rely has its different power. there's two up in front together, the one on the left is the one for your a/c compressor...and i think the right one is for your condensing fan...
