so here's the deal. the AC seem to blow hot air in and it's between 78-88 degrees here and i need the AC. 2 days ago i bought a can of gas and my buddy (who has the gauges and the hole thing to put the gas in )and I put the gas on the car. it seemed to have air bubbles all around, but they where gone by the second can. But now the air is worse. (this has been a problem for a few months now)

any ideas?

(the issue is w/ the accord)

 

When you first read the pressure in the system when it was running, what was it? Did you friend evacuate the system before adding R134a?

As for some simple things to check...

Start the engine, and look at the compressor pulley. The clutch (metal plate in front of the pulley) should not spin. When you turn on the A/C, both cooling fans should turn on, and the clutch should start spinning with the pulley.

As for possible leaks in the system, the o-rings can deform over time and cause a leak to an improper seal. The R134a in the system evaporates immediately, but the oil in the system will be left. At every connection that is bolted together look for oil or dust sticking to the oil. That would be a sign of leakage.

Let us know what you find.

 

What year is your Honda? Are you referring to bubbles in the sight glass? Does your Honda take the R134a or R12?

 

I thought that he was referring to the 2000 accord in his signature.

 

I haven’t seen many R134a systems use a sight glass as it will still have bubbles when fully charged and that is why I asked what vehicle.

 

it is the 2000 in my signature and it does use the r134a gas... PAhonda: i checked but i cant seem to find any leakage and the ac didn't work even before adding the r134. a friend of mine told me it could be the evaporator(?) or the filter and whatever is attached to that...(don't know the name of it...)

 

The a/c not working could be caused by a number of problems.

Do the fans come on when the a/c is "on"? Does the light on the a/c button inside of the car turn on?

Does the clutch plate engage when you turn on the a/c?

How much R134a did you add? Overcharging a system can be dangerous, that I why I wanted to know what the initial pressure readings were on the high and low side.

 

oh ok... well the fan turn on, the light does as well. as far as the clutch plate engageing i have no clue (how will i be able to tell?)
I added half of a can first, then like 1/4 of the other can.
As for the readings, well i can't remember, but my buddy said that the blue gauge was too high (like reading 85-90F as the temp inside the car insted of 30-50 something.)
did that help?

 

first off both fans should turn on with a/c on,,,,,,,,,,

secondly,, hook up the pressure gauge and read both sides low and high and let us know
to see if compressor is engaged , just start car, turn a/c on, open the hood and look at the compressor , see if the outer part ( the clutch ) is spinning ....

i would totally evacuate the system. then put the proper amount in ,,, 21-23 ozs

if system is overcharged it will cause compressor damage

 

thanks desert, i'll do that tomorrow. i'll let you know asap....
