ok so in my 97 XJ i have great A/C. i know i know so what r u complaining about. well if i have it on for a certain aamount of time no matter what level the fan is on it eventually hardly blows any air out. its not the fan cuz i turn the level up and u can here it blowin real hard but it sounds like somethin is cloggin it. now if i turn it off for a while it works just fine again. anyone ever had this problem and/or know how to fix it? or if anything tell me what exactly is goin on

You could be a little low on refrigerant. Check your pressures with a test gauge.

Sounds as if it's icing up. I think there's another thread recently here about which switch it is that controls compressor cycling. I finally got mine working after the clutch seized up, and now it's doing the same thing, though not every time.

it is icing up! when i have the fan on high it works just fine and has alot of air but after a while it hardly blows any air!! i asked a guy i know at the dealership and he said that it is icing up!!! i just usually turn it on low for a while and then its ok! and maybe it could be the controller of the ac, the whole unit on the dash that controls the louvers, it might not be working really well! i changed mine once

I know you're icing up, that's why I wrote what I did. If you don't want some help, then don't ask.

Like said before, it could be under or over serviced. AC systems are pretty picky about how much they've got in them.

I don't understand how a low charge will cause icing up. Doesn't that just cause it to cycle more often and eventually (assuming the low-side pressure switch is working) not come on at all? I also don't understand why this happens with the fan on high, but resolves itself after putting it on low for awhile. Shouldn't it be the other way around if its icing up?

I can see if the low-side switch is whacked, the compressor will run the high side pressure too high, which would cause too much cooling and hence icing. So I would agree that the first step would be to watch the low-side pressures and make sure they look right. You can get a cheap gauge usually with a R134a can attached at Walmart.

mine does it whether the fan is on high or low

I guess since you don't want to believe a certified tech, then do some yahoo or goggle searching on your ac icing up. You'll find your refrigerant might be low, or your coils are dirty as the likely answers. It's not hard or expensive to do a pressure check, and it can tell you a bunch about your system.

What type of tech are you? Just asking because auto and home/commercial hvac tend to be different. It's not unusual for a home unit to ice up because of low charge, but I've never heard of it causing a freeze up on an auto setup. The advice to verify the charge with a test set is still valid advice.

Cracking open a 95 FSM and looking at the FSM a/c diagnosis section, under icing up it says the fin temp switch is likely faulty. There is a temp switch on the evaporator coil which if it's faulty or fallen off the coil, it won't be able to signal the PCM to cutoff the a/c and the coil will freeze up. So regardless of system charge, it's suppose to cutoff the compressor if the evap core gets close to freezing. There is a plug for it under the dash, so you can check it with a meter without having to tear into it. I can't guarantee this is the same for a 97 model though.

could it be a vacuum leak, sending the air through the defrost vents?

cuz im 21 and im part of the text message generation

Because I am 21 and I am part of the text message generation.

Also what does it matter if you obviously understood everything I wrote? It makes typing quicker for me so I don't see the problem if you can understand what I am writing and it makes typing a whole lot faster for me. Oh and its not just texting that we use that for its also for instant messaging. You could say the same thing for all the abbreviations that people use for things on here, like for instance LCA (lower control arm). Why not just type it out, oh wait because its quicker. I could also ask you why you spelled California with a K, but I don't really care and I can understand what you wrote. Please next time if what you have to say doesn't pertain to the question asked in the post don't waste everyone's time with your smart a** comments. Thank you

Being 21 and part of the "text message generation" is irrelevant. You aren't text messaging. :)

You seem to have a problem expressing yourself. You told me twice that it makes typing quicker/faster for you. :) If you were really concerned about how fast you typed, you would have only stated that once.

I was supporting my point when I repeated myself and no I don't have a problem expressing myself. The fact that I am part of the text messaging generation IS relevant because not only do we use it in texting and iming (instant messaging, didnt want u to get confused) we also use it in e-mails and in anywhere we have to type something that isn't gonna be turned into a class for some kind of grade. That my friend is how it is relevant. Opps I restated how its relevant I must have a problem expressing myself. I can be a smart a** too. Now please nobody wants to hear your idiotic comments about how I used text messaging short hand in my post. This is a place for talk about jeeps. Thank you

Wow, you must have had somebody else type this in for you. :)

When you grow up some more and get out into the real world of jobs, office politics, etc.. you will soon find that if you express yourself like that amongst your coworkers that you will give the wrong impression that you are ignorant.

When you fill out a job application (assuming you are not in college and have already hunted for jobs, etc) do you use that text messaging short hand as well?

I've seen it a few times and those are the applications that go into the "call them back later IF we can't find anyone else pile", simply because of the first impression given.

Was I being a smart ass? Sure... Was it to do you harm? No. I actually was trying to show you how it can get you negative attention in places where it might harm you financially (not getting a job simply based on the hiring manager not liking the text messaging style of writing).

Take it for what it's worth.

I don't think pointing out to people that they aren't communicating to everyone is being "catty". The last time I looked up "you" in the dictionary, it wasn't spelled "U"; and "because" wasn't spelled "cuz". When I read a text filled with shorthand, of any kind, I skip over it--I don't want to spend time translating. You want me to spend my time understanding YOUR problem, use correct English and spelling to ask it.

Ok you little ignorant prick. I am in college at Georgia Southern Univerersity where I am a business major thank you very much. I have never filled out a job application using short hand I know how to give a proper first impression. I would not use short hand in a professional business environment. I use it when I am on the internet and conversing with friends. Now please shut the f**k up and let people who really want to talk about jeeps and that don't pick at how a person chooses to type on an internet forum because they are a bored, arrogant a**hole, talk and leave your smart a** comments somewhere else. Thank you

I sure hope you check your academic writing more carefully than you do this stuff.

Ben, not to belabor the point, but if your intention is to get courteous, competent help from a number of people, it should be your primary object to make your posts easy for them to read, not easy for you to type. Of course we can read text message junk and capital letters, but why should we bother?

And if you really want to expatiate on what this forum is for, perhaps you should join NAXJA!

See now the differeance between what you had to say about my typing and what they said is that yours was polite and courtious compared to what they said which was just complaining and belittling (hope I spelled that right). Also I would like to join except I am a broke college student and can't afford much so I had to go the free route but thats just for now I will join eventually.
