ok im not good with AC so someone help me out
I know if the freon gets low the compressor wont engage at all

so on my 92 hatch
I flip the ac on and the clutch DOES engage and the compressor spins does that mean IM full of freon?

no cold air comes out and its getting hot here
so what do I need more freon?
or something else to be checked?

you can go and pick up one of those freon charge kits at your local parts store.it is the freon can and a gauge included. you can use the gauge to read if you are actually low or not. if you are add until charged.

 

i will try that but last time I did that on ,y del sol somethign weird happened it did blow cold air BUT when the compressor was on it SEVERLY dragged the engine down

WAY WAY more than normal
maybe because I charged the system and didnt evacuate prior

hmmm...i really don't know, this what i did on my hatch and never had a problem.

 

put oil in the a/c system, you probably had a leak.

 

ok dod this went and got the quick charge with oil and some kind of leak helper in it and a gauge

when I hooekd the gauge up it was in the green maybe 5 psi low so I topped it off

didnt help

it blows kinda sorta cold but its still hot def not like its supposed to be doing

whats the next thing to check?

 

my ac clutch is making a squeeky noise what can this be, i already put oil in.

 

your compressor took a crap. rebuild it. could be seized or could have a bearing failure

 

check out your evaporator, could be filled with dust etc. i would recommend getting a manifold guauge set and seeing your pressures and compare them to specs.

 

Well unless it was converted to r134 that system is r12 freon. The 2 types are not compatible with one another. the system should be evacuated and have the r134 added to it you might have to have a dye added to check for leaks good luck

 

nope its already converted
where is the evaporator ill check it out

 

dont mean to jack the thread, but where do u put oil in? when i turn the ac on in my 00 si, the motor seriously draggs when the compressor kicks in, but still blows cold air. any ideas?

 

could be a bearing failure, theres a special kit that injects it through

 

so how do I access the evaporator and when I get to it can I simply clean it?
or replace it

 

jesus, gotta love diy freon charges. u have no idea how low your frean sys. is, u have no idea how much to put in. your pressures should be about 200-240 high and 35-50 low, if that helps. the gauge your talking about is low side only. is your comp. clutch cycling alot? on-off.

 

no its not cycling it comes on and stays on when u turn the ac on

only thing I guess is the evaporator needs to be checked out

freon is 45 psi low side

 

feel the low side line @ the evaporator, it should be COLD. is the blower motor working good (alot of flow coming out the vents)?

 

u mean up close to the firewall
feel the low side right there?

 

yes, and also, does the condenser fan come on

 

yes condenser fan comes on soon as u clock the ac on

 

take it to a pro, your gonna do more harm than good if you have no idea what your doing.

 

well I touched the low press line at the firewall before it goes into the car its "kinda" cold I rechecked the freon and its at 45 psi

 

I had the same problem on my civic a/c would almost stall the motor at idle. But it worked well at 1500 rpm and above. It turned out to be a bad ground near the compressor. The idle controll was not getting the message that the load on the motor had increased. I hope this helps.
