Air Conditioner Problem

After enjoying my Dodge Custom Van for several years, suddenly the air conditioner packed it in
I haven't had time to check it out yet, but maybe those with considerable experience can serve
as a sounding board. The compressor comes on for about 2-3 seconds, then cycles off. Constantly. Holding my hand on the lines to and from the compressor, I feel neither cool nor heat. Would low refrigerant charge cause this? I have been afraid it might be high head pressure, but would appreciate any comments. I am ready to sell this unit, and get something more in keeping with my
ancienité. Just need a little validation.

Thanks for the email and the great question. It sounds like your air condtioning system has lost its refrigerant. You may try charging it with a little freon and then using a refrigerant leak detector, sniff around for a leak. If it is something obvious, like a loose hose, you can fix it yourself. Then recharge the system.
