It means that the the AC is low on charge, you have a leak, this light is triggered when the AC compressor cycleing times go beyond a pre-programmed number per minute.

Where is the fitting to refill the air conditioner. The suggested hose onlly fits one fitting and will not serure itself. Please advise,

i would suggest taking your tahoe to a certified air conditioning specialist, the problem may not be that it low on refridgerent and there are legal risks if you get caught releasing any type of refridgerent into the atmosphere.

that said, if you still want to do it yourself, look for the fitting closest to your condensor, it should be the low pressure side connection, and intall the refridgerent as a gas only, turning the can upside down to make it go faster would introduce liquid into your system at the wrong place and cause your compressor to lock up or break.

hope i was able to help you, good luck!

Not sure what model but its a 1993 buick thee air conditioner needs to be fixed can it be fixed inexpensive?? i think the jerks at firestone jerked with it and made it quit working do you think my local...

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.

How do i recharge my a.c. My air conditioner blows out warm air. why and how do i fix it?

if the system is low on charge u must repair the leak before you waste the $25 on refridgerant, most likely the AC compressor is leaking and will need to be replaced, charging the AC after replaceing a compressor requires special equipment, so find a good shop.

Im trying to charge the air conditioner in my 2000 olds intrigue gls which is the high side and low side i would also like to know on the temperature control it says econo, i know it has air but it isnt...

If it's a 3.5l, high side is near the air cleaner, low side is at the firewall. Econo means compressor is OFF when light is ON (backwards). A low charge will cause hot air on left and cold air on right vents.

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 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.

Air conditioner blows hot air

this can be a few different things going on. 1. does the clutch on your compressor engage when a/c is turned on? If so, does it cycle on and off constantely? If its cycling, your low on refridgerant, which indicates that theres a leak. System needs to be checked by professional. If compressor stays on, and you got hot air, it indicates that the problem is with the heater control valve. Normally, this can be found connected to one of the heater hoses located on passengerside engine compartment. It might be electronic, or vacuum operated.

The air conditioner has a hissing sound.

Most likely the system is low, but not low enough to shut off yet. Have it checked for leaks by a competent technician - probably needs an evaporator.

Air conditioner blows hot air, checked coolant and it is full

There are a few different possibilities for a vehicle doing this. A low refridgerant level can, or a temp control on the dash is not operating properly.
