gotta a 95 civic ex 1.6l here with an ac problem a licensed ac guy fills it with freon and its cold for first week then it just blows on a warm day it will blow warm wonder what it will do on a hot day. he said its cause something is wrong inside the dash but what exactly is he talking about it was so expensive for me to let him do it he quoted more than honda too , but to fill it with freon it was cheap.

any way how do i fix it i just think my car is not registering how hot it really is. heater works. just had the radiator replaced . no leaks in any system cooling or freon at all.

I have no idea what you said. Might want to try some punctuation in there somewhere.

All I can make out is that you paid a guy a lot of money and all he did was add Freon but it no longer blows cold.

the car a 95 civic ex 1.6l z6 trans.
the problem:
ac blows warm (80 degrees on a 85 degree day ambient temperature)
wonder what it will do on a hot day.
why i am here:
I am trying to diagnose the issue so i could fix
Whats going on? everything works properly except the function of making the air cold.
freon was added into the system after finding out in the beginning there was only about .8 oz's of freon in it.
so freon was added and pressures were ok with no leaks at the time with uv light test and dye test.

what now?
I later tested the pressures myself
low side was 29 on an 85 degree day too low
high was normal

ejfromwestbay

Ok anyone else

take it somewhere else, or learn to type better english imo

I added punctuation to your posts so that you know what members are asking for:

Take you car to a different shop for a diagnosis.

Could the "Thermo-Expansion Valve " reason the ac doesn't know what temperature it is in the car. Could I have a bad "Thermo-Expansion Valve "

JonGP4

Based on a better worded post, amazing what commas and periods will do. I believe the flap inside the dash, that controls the flow of hot/cold air from the heater core and the evaporator is not functioning correctly. The flap is moved/controlled by wire, maybe the wire is not hooked up. Does the slider from cold to hot, move fairly easily? If so that's most likely the problem.

ejfromwestbay

Also can i replace the Thermo-Expansion Valve without removing the refridgerant

JonGP4

If the valve was not functioning the compressor would not turn on. I don't believe this is your problem. Also the guy who filled up your car with freon would have noticed the pressures were way off.

JonGP4

No

ejfromwestbay

thank you i will toggle the slider and compare to an accord the coldness

JonGP4

The slider should have some resistance when you move it, if it moves easily then it's broken. The wire/flap/or something related could be broken. This would require removal of most of the dash, which is why they said it would take several hours.

ejfromwestbay

My slider slides as normal at first when I tested the slider it seemed to blow cold air once I put it on cold but 15 minutes later that wasn't the case.In fact it still doesn't work. one week after I found out my low psi level was at 29 on a 85 degree day and high side was within range 250 to 300.so I Added more freon to 41 psi and one week later not cold anymore.Compressor clutch still engages and fan still comes on and radiator fan intermittently if that matter, but I think that's normal.

JonGP4

On a 95 civic the slider is not electronic, it's actually a manual wire that moves a flap, if you take it apart you'll see what i'm talking about, you actually can see the wire if you take out the radio. As for why it worked all of a sudden, it's hard to say, maybe the AC guy went under your dash and moved the flap by hand? And in the process of driving it moved back to heat. In either case i believe you have found the culprit.

It's unclear what exactly you are saying here^. Are you saying that the compressor clutch does not engage and the condenser fan does not run when the A/C blows warm? Are you also saying that sometimes the clutch engages and the fan runs and that, when this happens, the A/C blows cold?

If you are prepared to describe the problem clearly, to do some basic troubleshooting and to answer questions, then we can help you. Otherwise, taking your car to another mechanic is your best option.

What I meant to say was, "my car still blows warm air from the vents at 80 degree temp on a 85 degree day. on that same day the ac compressor will turn on when i push the ac **** in,(so it lights up blue).my condenser fan turns on at all times when car is on. my radiator fan is intermittent like it should when the car reaches a certain temperature inside the engine coolant."
further news;
I tested low and high side ports with a guage
-low-29 psi
-high-250-300 cause all i cared about was it was within range
-temp outside was 85 at the time.
I decided to put freon in myself,r-134a of course.
-set the guage on ac kit to 85 temp
-hooked up the ac line to low side port
-then the can to the kit hose and guage
(it took only like 3 minutes to get to 41 psi on low, but I still did the 15 minutes as the can requested.) and a week later it still blows warm 80degrees with a household thermometer at park.ac compressor still works, as does the condensor fan. please help.

Change your condensor, buy a new one from Honda.

ejfromwestbay

how do i know that's what i need to replace and how much is it? can i do it without removing the refridgerant? or just let a pro do it. I'd really like to know how that is the part i have to replace.

ejfromwestbay

my radiator was replaced with a brand new one 3 months ago

ejfromwestbay

so today june 27 2011, at 87 degrees ambient temperature outside, i had my car tested at a bar licensed repair shop, which told me low side was at 4psi and high at 80--almost empty and it was leaking from the ac high pressure line and the compressor the leak in the line was close to the compressor. where do I go from here?
how do i replace the ac compressor myself i am good at all data and michlin on demand , but have no ability to get to it.
By the way I'd have to say this is the best route to go "getting my car diagnosed for 30 mins of labor through pennysaver ads iin the mail"

That sucks. I suspected it that you have a leak. How come the guy who put the freon in didn't notice a leak or the leak? Change the o-rings on all of your hard lines. It's cheap from Honda, only thing is you have to put in the labor work. Where did you get your car recharged and diagnosed?

ejfromwestbay

i went to three shops total one wasn't a shop it was a mobile mechanic, other two were reputable shops and i filled it once anyone got and idea on how hard its gonna be or how long to r & r pump and high pressure hose and o rings

rhymeshark916

What?
