You may have a stopped up orifice tube,feel of the large ac line going into the firewall,see if it is cold,if it is,then the inside door for the temp is not working,but if the ac line is not cold,remove the freon and remove the orifice tube and clean it,or replace it,then charge the system back up.If this was at all helpful,please rate,thank you.

You put WAY TOO much in, most newer systems only need 2oz. to 14oz.,you need to diagnose this problem first

HELLO
THE 1ST THING THAT MUST BE DONE HERE IS TO HAVE THE AC SYSTEM HOOKED UP TO A SPECIAL AC PRESSURE GAUGE SET TO SEE IF THE SYSTEM IS LOW ON CHARGE DUE TO A REFRIDGERANT LEAK. THAT IS THE MOST COMMON CAUSE OF NO COOLING IN ANY CAR OR TRUCK NO MATTER THE MAKE OR MODEL

The AC not working wil not affect the engine coolant temperature. The engine cooling system is a seperate system fromthe AC system on your vehicle.
The AC could simply have a small leak and the refridgerant has leaked down and needs to be replaced. If that is the case you can have what is called a "pep charge" performed and you will have AC working again until it leaks back down. Before you ask, I can't tell you how long that will take because it depends on the sevarity of the leak(s). Might be a couple of days might be a year. That should generally be about $40 or less depending on how much refridgerant they need to add to your system.
Of course you may have AC components that have failed such as a compressor. This will be an expensive repair. There is no way around this. Usually when a compressor goes out, you need to replace the compressor, receiver/dryer, orifice tube, all of the refridgerant, and have the system flushed. This is costly.
Many shops have proper AC equipment and properly trained techs that can peform an AC diagnostics for $40-$50 (in my area) that takes about an hour or so. This will tell you if the refridgerant is low, indicating a leak, or if your compressor or other component is not functioning properly.
At my shop when a customer pays for the Diagnostic and we find that the system is low on refridgerant. We offer to re-fill the system (customer has to pay additional for the refridgerant of course but no more labor) and add a special UV dye to the system. Then I ask that the customer drive the vehicle for a couple of days with the AC running then return. I can then use a special UV light and glasses to find the leak point on the AC system by locating the point where the dye leaked out. This is all included in the initial diagnostic charge and does not take too much time.
From there we make the decision of whether to fix the leak or not. Often times the leak is repaired for minimal cost as the leak ponts are commonly very inexpensive parts.

Air conditioner isn't blowing cold air


Could be a number of things...electrical connections causing the compressor not to run. Turn on AC and turn your thermostat all the way to cool...now visually check to see if compressor is engaged and not just free wheeling. Most likely you lost your refridgerant due to leak in the system...would need to find leak and repair then have your system re-charged with refridgerant. Best case scenario...your system just needs a charge of refridgerant due to not having enough.

You have a leak in the ac system, u will have to have the system leak tested and the leak repaired before adding anymore very expensive R134 refridgerent.

My a/c in my buick wont work what could be wrong and what are the cost


the number one cause of the AC not cooling is low refridgerent charge in the system (caused by a leak), the next is a defective compressor, the average cost for a leak check/repair and a recharge is around $300.00

A/C not blowing cold air


Hi daveyrichard,
Just a guess....it sounds as if your leaking refridgerant gas from your AC unit. Maybe you didn;t need to change the compressor. the leakage could be on either the high pressure or low pressure side....Something that may help is to mix up some soapy water, use plenty soap, then sponge the mixture around all the joints that you can see....go as far as you can and as close to the fire wall between the cabin and the engine compartment....With the AC turned on, look out for bubbles....If you see them, thats where your leakage is.....Hope that this imfo helps you to solve your problem and keep your cool.
