our a/c suck?

[phreak965]

hey, i just got my a/c recharged and it's cool and all but why isn't it FREEZING when i leave the highest fan setting on a/c on for a long time, my tiburon is the same way as my eclipse. my parent's chrysler lhs can actually freeze you if you leave the temp setting all the way down. does anyone else have this problem too?

depends on the wear on your cooling system. my GSX is colder than any other car I've been in.

on that note, my NSX is fully charged, but doesn't get very cold at all, because the drier/evaporator needs to be replaced.

Your car is 10 years old, what kind of maintenance has been done on the a/c system?

It could be anything from a compressor going out to something as simple as its not fully charged. I converted my 91 to r134 and it will freeze you to death. When it was charged did you check the high and low side pressures?

 

[phreak965]

as far as i know it has only been recharged and no other matience has been done to it. i didn't charge the a/c, i took it to a chrysler dealership to check it out and make sure it was in good condition. how can you tell if the drier and evaporator needs replacing?
edit: i did check the low side w/ a pressure gauge and its reading 44-45psi. but i was told to never hook anything up to the high pressure side as it can do damage to the car and yourself! :/

If you want it to be freezing, go to firestone. My manager used to be the manager their and he had his done their. And his goes down to the mid thirties, they use some addictive their.. Any normal car should be able to bring your car below 50 degrees. To check, you would need a thermometer of some sort. Stick it in the middle vent and turn the a/c to the coldest position, and the fan speed to low. Give it 10 minutes and if its not below 50 degrees, then you may have a problem somewhere. This test will not work outside in the winter time.

When you have the fan on the highest speed setting it will blow warmer then a lower speed setting, as the air is moving faster across the evap core and warming it up the slower the fan speed the less air moving across the core the solder it will be

ok, thanks for the tips guys, i'll try em out later and get back w/ ya

 

[phreak965]

the tiburon gets to 40 and the eclipse to 48. but wow i never realized that it would get that cold. i was always in the mindset that more powerful fan = better . i think that this will be good enough for me but do you think maybe my drier and evap are still not up to par? or maybe the chrysler has shorter a/c lines or something making the a/c colder?

 

[terminaltsi]

alot of it has to do witht he size of the evap core and condensor. they are just like intercoolers. a larger more efficient core will provide colder air out your vents. space constraints in dsm's require smaller evap cores, which means the a/c won't be as cold as in a larger car with more space. of course, overall system efficiency is better on a newer car too, so they will produce colder air.
many factors dictate how cold the air will get.

would it help to pressure wash my condenser? or would that be bad for it? maybe not much of a difference @ idle?

BEST thing you can do is just jumper out the Heater Core Supply Hoses & leave the Heater Core with NO Hot Water supply - The Climate Control Systems in these things are PURE junk, as in most cars these days - So your AC is trying to overcome the QUITE considerable Hot Water temps we generate during the Summer and the 'FLAPPER" in the Climate Control System LEAKS Heater Core generated Hot air where it AINT supposed to be unless you are trying to WARM your AC temps.

So, instead of the coolant hoses going in and out of the firewall(to heater core) you can just loop them two together? Will this effect the engine cooling any considerable amount since there is less heat being disipated by the coolant?

i want my heater in the winter w/o having to rewire each winter. hehe

 

[Pyrice4]

I live in Florida and the temperature index was 105 degrees all week...

 

[phreak965]

oww that sucks, it's 93 here...pretty humid too, but i'm sure not as bad as florida D:

So put in a valve, like all foreign cars used up into the eighties.

big no-no, you'll bend all the delicate fins on the core, decreasing efficiency.

best you can do is clean it out with some lightly compressed air, and pick out the big stuff by hand.
