You probably over filled it. Unless you have a recovery machine bring it to a HVAC Repair Shop or equilivant.
If your not careful with refrigerants they can seriously harm you.
Remember if your thinking about releasing refrigerant into atmosphere its illegal to do such. Also if regrigerant is not recovered properly(even if its just a little) you risk the chance of getting moisture into your system AND THATS A MAGILLA TO REMOVE..

Sounds like its over charged, when you added freon to it did you have any gages to check what the pressure was after charging it?

It could very well be the compressor or the compressor clutch. There are variations in the clutch which make a difference in whether you can change the clutch without replacing the compressor.
The A/C compressor has bearings and they require oil in the Freon to lube them and the other moving compressor parts.
The oil is added in the Freon Low pressure port and the oil is available separately or mixed with Freon. There are different weights of this oil just like motor oil and you should use the correct type for your Brand.
There is a small chance that oil will solve the noise problem.
The thing is that you have a sealed system, and if you need oil, the original oil leaked out. You may think that this will be a Summer only problem, but the Compressor is made to turn on with the Defroster function above a certain temperature.
You add the oil just as Freon. If you watch the compressor clutch operate, if the noise is present full-time without the compressor engaged, then the clutch may be the only problem with the A/C. If the clutch engages and the noise then starts, it is likely the compressor.
As I earlier indicated, the A/C clutch may attach different ways. Left hand threads, snap rings, and some may require a pulley puller. Lack of room may require lowering the compressor while still connected to Freon lines in order to use a puller.
So look at the operation of the A/C clutch. When the front clutch plate spins, it is driving the compressor. If the compressor is noisy, then add oil. It may solve the problem.

2000 dodge durango, a/c compressor stopped working after freon was added, did I do something wrong?

at a rough guess you add excessive amounts of freon and that caused the compressor to seize up
gas is added using pressure gauges and not by the can
besides that did you use the correct gas as the r134a runs at a much higher pressure and will deliver liquid back to the compressor which is not good for the operation

My daughter's 2000 Dodge Neon's air conditioner wasn't cooling very sell so she took it in to have freon added. The shop drained all the freon out and then tried to add new freon but none will go into the...

you need the compressor running to get freon into the system
using gauges on a manifold you allow the compressor to suck the gas in to the system until you get a pressure reading at the high side gauge
That is the correct amount of gas for the system
take it to an accredited ac specialist shop to have the job done properly

Where is the horn located

For Horn on 1995 Dodge Neon
  1. Loosen the lug nuts on the front tire on the driver's side of the car.
  2. Jack up the vehicle, making sure it's high enough to clear the jack stands.
  3. Securely place the jack stands under the vehicle.
  4. Remove the tire from the car, and, if necessary, remove the inner wheel lining to allow access to the horn.
  5. Locate the horn and wiring, which should be located inside the front bumper of the car, slightly above the area of the tire.
Hope this help (remember comment and rated this).

1995 j30 air conditioner just blows hot air. set to auto and no noise from compressor. happened all at once, working when car was shut off but not working when restarted. compressor going bad or a switch...

I would start with adding freon to system, from what you are stating freon is low. You may have a small leak, so use freon with leak seal, also use freon with gauge so you dont over fill and blow orings.

1995 Chevy Suburban blows cold once charged then hours later hot

Its a leak ...probably concealed like in an evap housing or rear air unit and lines (if it has that). Prob at this juncture I would remove all the freon and bring system into a vaccuum with a pump and see if it will hold vaccum for an extended period of time. A bad leak will not hold srong vacuum very long and much cheaper than wasting expensive and enviromental un0friendly refrigerants.
