Hate to break it to you, but AC issues are not reserved to domestic vehicles. AC systems are high-stress systems, which people tend to neglect until they don't work anymore (which is usually when they need them most). Then they half-*** the repairs to save a few bucks, and end up costing themselves more headache and money in the long run.

AC problems can be frustrating, and expensive. I know, I just spent $350 in parts to fix mine, and they're not even here yet! I also still haven't purchased the new orifice tube, and the refrigerant, so that's gonna be another $40-$50. All this because the previous owner half-assed something, and ended up ruining a bunch of other stuff. NEVER, EVER, EVER use A/C Stop-Leak. It doesn't fix anything, and causes nothing but more problems.

I know exactly how you feel running down the road in high-temp weather with no AC, and the windows down. It ain't fun.

I've had more foreign cars come in with AC issues, than domestic; including Hondas and Toyotas. So there it is. If you want to go buy a whole new vehicle, and cry yourself to sleep because your inferior tools, and lack of general AC knowlege prevented you from doing your very own half-assed repair, then go ahead. You'll be doing the same thing soon enough, with whatever vechicle you choose. Only next time you'll be pissing into the wind on a Toyota forum, and making people not want to be much help there either.

I suggest you humble your self down a bit, and learn to behave like an adult. Or, of course, you could always just move to a cooler climate. What's that saying? "If you can't take the heat, stay out of... [Texas]"

Thanks for all the mostly worthless advice!

Got input on why my AC went into this high heater mode yesterday?

Is it freezing up?

This morning at 78 degrees ambient it worked great for 50 miles to work....????

"Neglected"...???? What was I supposed to do for the ACin the 3 yrs and 100,000 miles I've had it?

WOW, you think AC systems are so complex....and "high stress".
Most any monkey with a revolving SNAP-ON account can repair.

Somday YOU MIGHT cross into true high tech wrenching and get into 800-1000 HP Engine design/buuilding/testing/racing. In the mean time, stand around drinking coffee waiting for th Roach Coach and SNAP-ON truck charging people $80+/hour.

All mechanical assemblies have what is kown as a lifespan. I have not begun to reach that on this TAHOE surely?

TEXAS....My Born and raised home. Been other places and lived in a couple but TEXAS is where I lay my head and repair simple little vehicle AC systems under my FRONT YARD SHADE TREE.

Of course I am kind of joshing with you a bit...be nice as it will carry you far in life.

To the GMC dealer Monday when the roving mechanic gets back again. And I have been trying to avoid dealers for 30 yrs, especially dealer repair shops!
Of course I do have friends believe it or not in the car business.

Why all the hot air yesterday.....Out of my AC vents that is? That is the question now.

Thanks

Any time. Thanks for the mostly-worthlesss information on your problem, and the bad attitude.

Cause you don't know how to fix your car? Did you check your blend doors?

Could be. If you'd get some decent manifold gauges, a multimeter, and basic knowlege of AC systems, maybe you couldtrace it out.

Well maybe the problem is that it's hot right now? The cooler it is, the easier it is to make the air feel cool to you? Just cause it seems to work to you, doesn't mean everything is working fine. Next time it's cool out, drive it arround with a thermometer in the vent, and see how cold it's actually blowing. Might just be working "well enough".

For starters, how bout making sure your evaporator coredrains aren't plugged up?Keeping the condenserclear of debris, changing cabin air filters, etc.True there's not much maintanence involved, but there are things you should check on every now and again.

Did I say complex? Maybe not as complex as the 1000 horsepower engines you build, but there's a system to it, and if everything isn't working just right, it won't work.

If you don't understand the nature of how the AC system works (which you clearly don't) then I can see how you would not think that the parts of an ac system are subjected to high-stress.

100,000 miles is a pretty good bit of driving. Lots of AC systems don't last even that long. Some last longer. Just depends on how much you're using it, and under what conditions.

Yet, it seems, you can't. Ironic, no?

Actually, I got out of wrenching. Not much reward for the mechanics turning wrenches, just the shops who make the money ripping people off. The industry is a bit too unscrupulous for my tastes, so I moved on to more fulfilling endeavors. I wrench my own vehicles and the occasional friend's.

Yes, funny concept that.A "lifespan"implies thatit will eventually die, or have problems. That's the concept here. Expecting a vehicle to go much over 100,000 miles without ANY problems is pretty unrealistic. It happens, but more often than not, you're going to have to start doing a few repairs after that 100,000 milemark. That's life.

6th generation Texan born here. I know a lot of Texans, and for the most part, they're much more personable folk than yourself. Quit giving Texas a bad name. You seem more the entitled type, you'd probably do well in Kalifornia.

Yes, it seems to be workingwell for you.

No kidding? It's kinda hard these days, to throw a rock without hitting someone "in the car business". It's a big industry, people buy 'em, drive 'em, and sometimes their cars require fixin'. Foregin ones too!

Bones,
You've been screwing around with this for over a month now, I think that it is safe to say that you are not going to be able to make the repair yourself.

Take it to a shop and pay the bill so we don’t have to listen to your incessant whining, have some dignity for Christ sake!

BonesNTX

You guys are like a cartoon![:-]

I have asked a specific question and all of this dribble out of you two.

Idon't kow what I'm doing??? In my line of work, someone asks me a question I answer to their satisfaction. You guys aren't really much for answering people ith a problem question?

The is not the first trouble with this damn thing by any means. I really like this truck, it tows great and aides the Family on trips alot. Good in sand and heavy rains.
I do not like the cost and all of the mickey mouse crap that goes wrong and nowhere to go for advice except Stealerships.
TAHOE...Reminds me of 1970s GM quality......Wait, my 1970s GMs always had cold AC! (when the engine would run)

I used to live in California! Loved it and still do...to visit. You might want to venture past your city limits and get some exposure to other cultures.
Maybe somone will chim in with answer to my question if the goof ***** will stay out of the way.

Thanks again!

Alright, alright I'll quit screwing around.

Hold your Tahoe up to the computer so I can diagnose the thing and fix it online.

BonesNTX

It is the Big Black Thing right behind me....over my shoulder to you.

Come on MX...a little g=help please?

My high side is at 150 and low side about 45.

My understanding is my high side should be around 200-220 at 90 degrees?

Thanks

Specific question? Which "specific question would that be; "Why the hot air?"? Well, cause you're AC doesn't work! Satisfied?

In your line of work, do you have a lot of people who aren't willing to admit that they don't know what they're doing? In your line of work, is it customary for you to give free help to people who insult you? Sounds... Quaint.

Well driving a vehicle in sand a lot tends to be harder on vehicles too. If you're putting your vehicle through severe conditions, expect to do more repairs and maintenance.

Wow, and you think things get better with foreign cars? Hope you don't ever purchase anything German...

Did your GM's have rear air systems? Rear air systems which you allowed to fill with water? Listen, with that rear air system, you're doubling the load that's placed on that same small AC compressor, therefore making it work harder. The NipponDenso compressors that were installed in the Tahoes are notorious for going out at about the 100,000 mark. But that's a Denso (Japanese company btw)issue, not Chevy's.

I'd think that engine problems would be more likely to turn one off to a particular make of vehicle, than some simple AC issues would.

Oh I don't think I have to worry about not having enough exposure to other cultures...I've lived afew places, and dealt witha few different "cultures".

I just don't like socialism/communism. I don't have to go live in Russia to know that. I like California too, but notthe people.The people there are a bunch of whiney adolescents like yourself. Love the weather though.

Let me give you yet another bump so that they'll be more likely to see it, alright? Who knows,maybe you'll get lucky, and one of those monkies with the Snap-On account will come and fix you right up.

Oh no, thank you!

uraijit

Is the compressor cycling off at all with those pressures? What is your static pressure?

BonesNTX

Just couldn't answer my simple questions could you.

On and on you go with nonsense.....JEsus

You must be the new shiny wheel expert I guess...Damn sure aren't customer friendly I can tell from here. All customers are stupid MFrs...Right? A high and mightey Chevy wrench.....oh my!

3 German cars thus far just to comment on one of your idiotic statements. More maintainence is obviously expected.
A Chevy truck...Not really.....And should be fixed for more than 5K miles on all the other stuff that's gone worng numerous times.

Oh, and my TAHOE kept cool last night stuck at the beach to the frame in surf water for about 4 hrs waiting on wrecker!...You are some kind of freaking fool aren't you?
