AIR CONDITIONER STOPPED RUNNING

1991 Mercury Tracer

Air Conditioning problem
1991 Mercury Tracer 4 cyl Front Wheel Drive Automatic 180000 miles

Hi, I have a 91 mercury tracer, I go the AC fixed three months ago (had not worked in a long time) and it was working great. Now when I press the ac button, nothing happens, it just blows hot air. When I would press the button before the engine would work harder, now it won't. I did not find any leaks in the hoses or system. Any suggestions?

If you are sure it is full charged?
Under the hood passengers side firewall you will see a aluminum tank near that you will see a plug unplug this plug and plug it back in if air works the low pressure sensor is defected
