92' Civic A/C, "STOPPED WORKING"

[a94civicex]

Well after enjoying my ice cold A/C the past dew warm days we had, it completely stopped working:

Condensor Fan- not spinning
Compressor- not spinning or kicking on
20amp fuse not blown under hood fuse box

A/C button inside is illuminated when pushed in "green light" comes on but blows hot air! If it's not 1 thing I swear it's something else, lol. Is there a condensor fan relay & ac compressor relay, wires, plug connectors anywhere that I should look at that I don't know about? If so please let me know & if the a/c can be hard wired to a switch (temporarily of course) please let me know asap! Diagrams & Wire Schematics will be greatly appreciated. I need this fixed asap before it gets hot again & my wife/kids have to suffer in the good ole GA Humidity/Heat.

most likely low on freon or it has a leak, when you hit the button do here the "click" of the compressor engage? Look of the valve on the line and check the for pressure.

i bet you are low on freon. you could have a small leak somewhere. with out the right pressure in the system the compressor's clutch will not kick on. there is a pressure switch on the drivers side near the headlight and you can unplug the switch and jump the plug with a wire to see if its the compressor that went out. with the switch jumped the the clutch on the compressor will turn on. it has nothing to do with the switch inside your car. its only one of 2 things, either youre low on freon or the compressor went out.

If it's low on freon that won't cause the condensor fan to come on, because that fan should spin no matter what, right? It's not coming on at all when I push the a/c button, just getting the green light when it's pushed in! I don't hear a "click" when I hit the a/c button but i do feel the rpms drop a little & the condensor doesn't spin & the compressor doesn't spin at all. The 20amp fuse under hood isn't blown & 7.5amp fuse under dash isn't blown! PLEASE HELP ASAP

only way to tell for sure is to hook up a set of gauges. low side pressure should be close to ambient air temp when the compressor is not on. (ex. if its 75 degrees out pressure should be around 75psi + or - 5psi with the compressor not running) With the compressor running you should have 30-35psi on the low side. if its low add freon. if the pressure is correct and all the fuses are good, put a paper clip in the plug for the low side pressure switch and see if the compressor kicks on. if not you have a bad compressor clutch. if it kicks on you need a low side pressure switch. low side port is the smaller of the two. hope that helps.

also i dont think the fan will come on either. there is no reason for it to come on if the freon is low. i can almost bet that is low. look up the low pressure switch and jump it like you would look for cel codes and everything should turn on. if it does that means its low.

Okay, so your saying take a paper clip & stick it in the prongs on the low pressure switch that's attached to the top side of the cooling fan closest to the driver side headlight & turn the car on & hit the a/c button? If it comes on what does that mean, add freon & if it doesn't does that mean a bad compressor?

Yes. I would say you are low on freon too. Dont let the compressor run too long low on freon IF you are gonna jump the low pressure switch. You really need set of gauges.

No low on freon! I jumped the low pressure switch & nothing happend at all when I hit the a/c button except a slight raise in the rpms, no condensor fan spin & no a/c compressor spin! what is this telling me? Bad a/c compressor? Idk I'm going to take it by my mechanic & have him run tests on it & find my problem!

yeah bad compressor.

yeah bad compressor.

I hope that's what it is, lol
