'98 Ford Windstar. Drivers side door is closed but still shows an open door warning on the dash and the open door alarm sounds every 3 minutes. Last night at 12:30am I noticed the interior lights still on so I ventured out into the steamy night air, a humid 85 degrees soup and pulled the door panel and disconnected the harness to the latch and the lights went out and I went bed. My question is does the latch have to be replaced or is the switch at the latch replaceable or I'll probably just leave it as is (disconnected).

Hello all! My brothers a/c was working fine until today! All of a sudden it started blowing hot air. Now the compressor was turning on but the air was still cold. I pressed the valve to see if the system had air and there was. Then I demonstrated how I checked the system by releasing more air then the compressor stopped turning on. I bought a bottle of the legal freon and connected a wire to the battery to activate the compressor and it worked and the system accepted the freon. However the compressor does not stay on by itself now. Does the system need more freon or what can I do?
