Adding freon to ac - John Deere 6300,6300l,6400,6400l Tractor Radiator

I need year--make--model?
You removed the fuse and used paper clip in the fuse socket? I'm just trying to understand what you did with paper clip?

adding Freon may not be the answer but will cause unnecessary problems if not done by a specialist. Have an accredited ac specialist look at the problem as the ac may not be working because of a leak in the system. He may have also used the power wire for the radio and so there is less current available to work the ac.

Try disconnecting battery for two minutes to reset the system. Then start the car and check a/c operation.

You will see bubbles when freon is low....so, keep adding freon untill you see "no more bubbles" (clear)..as soon as it is clear STOP adding freon...You should be good to GO...

If the noise started after you added the Freon, then it perhaps is your AC clutch. Normally if you have an automatic AC system, then when the Freon gets low, the auto system will not allow the AC to engage, only allowing the fan to circulate outside air. In order to add Freon to the system, the AC lock out has to be over ridden, in order for the compressor to **** in the Freon. This in turn engages the AC system so that the clutch engages, thus engages your AC system. The clutch bearings may be at fault.

Needs to be checked for a freon leak, best way to do this is to recharge and add dye, with a uv light you will be able to fine the leak, most auto parts sell the dye, and the flash light you will need to fine the leak, good luck.

It sounds like by adding refrigerant to the system it may be over pressurizing. When this happens it will cycle on and off.

You will need to hook up a set of manifold gauges and monitor the high and low pressures to see what is happening.

On that model,it will cycle on and off while you add freon.If it does not ,then the ac system might have a problem.The low side pressure switch is located on,or near the accumulator .Unplug the switch and take the wire end plug and connect the two plug in`s together(cross it out on the wire).This will make the ac compressor engage and you can charge the system,do not leave the wire connected,plug it back up to switch.If the ac compressor does not come on ,then have the system checked out.

You probably have leaked out your freon after so much time. Try adding some more Freon if it doesnt stay charged you may have bigger issues.

Adding freon will not correct the problem. If you need to add freon, you have a leak, and you have moisture in the system, the leak should be located, mositure removed, then freon added. But to answer your question. Open the hood on, the left side you will see a round object called a dryer, you will see two pipes coming from it, one at the top and one at the bottom. The smaller is the high side, the larger is the low side. Obtain a can of freon either R-22 or 134a with an adapter for installing the freon. Turn the engine on, turn the AC to high. Add the freon to the ac using the low side.
