When i was buying a car i was specifically looking for one that had air conditioning due to the fact of just moving from washington state to hot *** south carolina so i pick up a 95 civic ex with air conditioning but like a dumb *** i forgot to make sure it worked i pushed the button heard the ac come on and then just turned it off the problem is it doesnt get cold at all it basically feels like i just slide the temp gauge on the dash all the way to cold and had the ac off and turned it on you know kinda like a pretty warm air that should be cold i have tried to recharge it, its fully charged. what else could it be?

Does the condenser fan run? Does the compressor clutch engage? Does the A/C button light turn on when the button is pressed?

95civicproject

yes the fan comes on idk if the compressor clutch engages where would you look for that and yes the light turns on when the button is pressed im guessing i would look if im looking at the motor to the front right of the header like right behind the driver side headlight and what would it look like when its engaged
thx

With the engine running and the A/C off, the faceplate (clutch) on the compressor should NOT spin with the pulley.

With the engine running and the A/C on, the faceplate on the compressor should spin with the compressor pulley whenever the condenser fan runs.

Before recharging with refrigerant, was the system empty? Or did you recover, evacuate, and then recharge the system?

95civicproject

im pretty sure that thing just spins constantly i will have to look again but when i tried recharging it i just went and bought a thing to recharge it and put it on the appropriate nozzle and it said fully charged thats all i did should i do something different

Former User

The clutch/faceplate should only engage (spin with) the pulley when the A/C is on. Double check that.

How much refrigerant did you add? It's very unwise to add refrigerant to a system before measuring refrigerant pressure on both the high and low sides using a manifold gauge set with the A/C running. Without this information, you don't know whether the system is full or has air in it or another problem. Diagnose first, then repair.

Hey thanks man thats going to help alot i will work on it a lil tomorrow and then figure it out where im at from there and get back at ya thanks for the help

95civicproject

clutch plate / face plate does engage when turned on and it turns off when i turn it off so that part is functioning properly still trouble shooting if ya'll have any other ideas as well i would love to hear them
thx

Hook up a manifold gauge set and measure the high and low side pressures with the A/C on and the engine at 1500 rpm.

95civicproject

ok so i read the forum thing that link you sent me and did wat it said it worked to an extent its alot colder but not seriously cold it said something checking the radiator to see if it is filled up you know by squeezing the lines top and bottom and checking the fluid and i did that does that help? idk
im sure it does but idk how i dont get that i guess i didnt think it had anything to do with the ac

Former User

If your engine is overheating, the A/C won't work as efficiently. Did you measure the refrigerant pressures?

95civicproject

no my engine isnt over heating but i was low on fluid in the resivoir so i filled it up still looking for some time to measure the refrigerant pressures you need hi and low right?

95civicproject

say i cant get my hands on a manifold gauge set what then?

Frostmane

It also happen to me, when I first got the eg, It didn't have any freon, it was bone dry.

95civicproject

yea well mine is full

95civicproject

i am super high on my low end side of my ac and super low on my high end

Former User

What are the numbers?

JoeScro

Check to see if the belt is attached to the A/c Compressor and that its not worn or not frayed.

95civicproject

90 on the L and 100 on the high

Former User

These^ look like static pressures. Was the engine idling at 1500 rpm with the A/C on (condenser fan running and clutch engaged) during this pressure test?

95civicproject

no my bad i forgot about that i be back in five with the new numbers going to go run the test now

Former User

Let the A/C run for 10 minutes on max blower speed and recirc before taking the pressure readings. Also note the outside temp when the test was done.

95civicproject

ok the high end was bouncing between 175 and 200 and the low end was at like 35 ish

and 80 degrees
