AC Compressor clutch/recharge

AC Compressor clutch/recharge
I noticed that my AC was not pumping out cold like it should. So went to advanced auto and picked up Arctic Freeze recharging can that has the gauge and everything with it. Followed the directions on can, when plugged tip on the gauge shot up to the red. I can see and hear the compressor clutch engaging and disengaging every 5 seconds or so. When it does that the gauge will go up and down all in the red. I don't know exactly what is going on, is there to much freon stuff inside or whats up. Please help advise....Thanks

If it is overcharged, there will be too much pressure on both sides. The system operates on differential pressures...... so, too much refrigerant is as bad as not enough.
You might be able to vent some by just putting the gauge fitting on the low pressure side, without the can attached. I don't know if they have a check valve in those...... of course, venting it to the atmosphere will offend a fair number of tree huggers, and isn't really a good idea. Better would be to take it to someplace that has a machine to recover the refrigerant. Bad part of that is, they would want money......
Just depressing the valve in one of the hose fittings (high or low side) will vent refrigerant, but, keep in mind, it is gonna be COLD coming out of there, and if your skin happens to be in the way, you REALLY won't like the results.

Using the parts store kits, its normal to see the pressure fluctuate into the red while charging. It should go up into the red, compressor turns on, pressure drops back into the green or blue, etc. Usually, if your compressor is cycling on and off every 5 seconds, that means there isn't enough refridgerant to keep the compressor running. I just charged mine this last weekend, it was totally empty, and it cycled every 5 seconds until I got it within 4 ounces of full.
As mentioned above, if there is too much refrigerant, then it will blow warm and can damage your compressor eventually. Best way to see the system pressure, is to plug your can/recharge kit into the line, but close the valve, it should show you where the pressure level is. If its in the red without the valve open, then its overcharged.
