2005 Dodge Caravan A/C not working

If you put too much refrigerant in the system it will shut itself off. Watch the compressor and the clutch. After you turn on the A/C, watch to see if the clutch continues to spin or shuts back off. This is the click you are hearing.

Are you saying I put too much refrigerant in, if so, will that keep the system from cooling? I believe the compressor is turning, but the system isn't cooling. What do I need to do?

Yes, overcharging a system can cause it not to work. You can check a couple other things too that could cause this.

Check the expansion valve, fuses for the A/C, leaks anywhere on the lines or A/C system, clogged condenser.

Where is the expansion valve located? I would think the fuses are ok, since the fan is working and the A/C will come on, i'll check all the suggestions you mentioned.

Thanks you have been a great help in diagnosing my problem.
