Just a quick ac check with your hand to see if the ac is fully charged. With the system running (compressor on) take your hand and feel the a/c accumulator (receiver drier). This is the silver can about 5" in diameter and about 12" high mounted at the firewall. If the system is fully charged, heater fan working, feel the top dome and then feel as close to the bottom as possible. If the top and bottom are cold = fully charged. If the top is warm and bottom cold,= low on charge.
