92 si hatch but for some reason i think when my car is left out in the sun for a while.. the ac doesnt work.. i mean yea the light turns on and the fan turns on but the rpms dont change and its just not working..

how can i find out for sure what it is.. cud it be somthing electricall.. cuz my fan 1 And 2 dont work only 3 and 4 but i can still hear it turn on when its on 1 and 2 just nothing comes out.. it usto work then stopped

As far as the blower fan not working on speeds 1 and 2. You need a resistor pack. Its easy to change out and is covered in a VERY NICE How To by Syndacate at the following link:

As for the A/C System. I would pop the hood and just double check that the Compressor Clutch is not engaging when you turn the A/C on. If you are low on Refrigerant the Low Pressure switch on the Condenser will keep the Compressor from running.

If you A/C works though when parked in the shade and cools then Low Refrigerant isn't your problem most likely and it could be the HVAC Panel giving issues. I have read alot about the HVAC panels not sending power to the Compressor when the car is really hot on the inside from being parked in the sun even though the little green light is on, on the A/C Button.

^I agree. Sounds like the common problem with the heater control panel.

swizz977

how can i tell if the clutch is engaging wat does it look like and wats a hvac?

Former User

HVAC panel = heater control panel

When the compressor clutch is not engaged, the pulley spins but the armature plate does not. When the clutch engages, you hear a click sound and the armature plate now spins with the pulley.

what about this http://www.hondacivicforum.com/forum...ad.php?t=47511 dam theres so many different things it can be what should i start with

Former User

The association of your problem with heat from the sun points to a faulty heater control panel, but start by telling us whether the condenser fan fails to run and the compressor clutch fails to engage when the A/C won't blow cold.

swizz977

well i dont kno if it has to do with the heat but what should i check first if u were me what would u do first

swizz977

i wish i knew what i was doing lol

swizz977

cud it be that im low on freeon and it wont turn on

swizz977

arite now today i get in my car and my ac is working.. so it cant be a fuse what could this be?

Former User

How could anybody possibly provide more than a wild guess if you refuse to provide any more details about the problem?

swizz977

the details are

my ac works randomly

i have enough freeon

when it doesnt work the rpms dont move like there saposto when its on like theres no power to it but the light goes on and still blows air.. like u kno when u push the button and u kno the acs on because u can feel it in ur car.. it doesnt do that when it doesnt work but it still lights up still blows air it just acts like there is no ac

Former User

See post #9 for the two crucial details absolutely needed to begin diagnosing your problem. In the first post, you mention that the fan turns on. Are you referring to the cabin blower or the condenser fan?

How come your ac only works somtimes.... Maybe it's because it's a 20 year old car?

swizz977

wats the differnce between the cabin blower and the condenser fan

swizz977

yea im pretty sure the condenser fan doesnt work when the ac doesnt work

swizz977

ok so today my ac was workin.. i shut my car off for like 20 mins and it stopped workin.. then i shut my car off again for 20 mins and it started working... now i noticed when it doesnt work under the hood on the ac the thing all the way to the right does not spin..

swizz977

anyone? what does this mean??

your problem might be an intermitant(sp?) relay. but RonJ is very knowledgeable at these things so follow his advice.

swizz977

ron jon u there buddy

The Condenser fan and Blower Fan that is inside the cabin are two separate things. The blower fan on the inside is in no way associated with the A/C System. The blower fan is what spins when you select a fan speed such as 1, 2, 3, or 4 and blows air out of the vents and at your face, feet or what have you.

When you are running the A/C you have the door on the HVAC panel slid over to the blue(cold side). This shuts a door under the dash and only allows the Blower fan to blow air through the A/C Evaporator Coil, thus blowing cold conditioned air at your face.

When you have the control slid to Red(Heat). That door then lets the air the Blower fan is pushing to blow across the Heater Core which then throws heated air out of the vents in the Winter.

The Condenser fan is under the hood on the engine side of the Condenser Coil. Pop your hood and you will see your Engine Cooling radiator on the passenger side along with its Fan. The Condenser and its fan is on the Driver side.

....I "assume" you are meaning the Armature Plate that RonJ was talking about earlier??? If that armature plate isn't spinning then the Compressor shaft isn't spinning. Since your A/C is working and blowing cold at times then it doesn't seem to be a pressure issue.

Seems more like a Intermittent faulty relay or an Intermittent HVAC control panel. As said earlier, your A/C button can light the Green light up when pushed in but still not send power to the Compressor.

ok and how can i fix the relay or hvac.. or find out which one it is

swizz977

ok well i just took the relay out and there is like lube or somthin inside on the connectors is that normal.. also the wires have a lot of greese on them is there somthing i can clean it with
