a/c problem of 1995 toyoya camry

[zxl4]

The a/c of my 1995 toyota camry suddenly stopped working after winter. Fans only blow air but not cold air. I checked the side glass when turning on a/c to maximum, it seemed nothing inside (no bubble). Two fans behind the rediator do not run either. However, when I put off the switch adjacent to side glass and "H" pressure valve, the fans start to run. I am not sure whether it is due to the low freon. Somebody mentioned to test the clutch switch by jumpering it. If clutch switch works, then it's low freon. But how to do it? Can anyone answer my question? thanks.

You should be able to activate the magnetic clutch by removing the 4-contact connector and connecting battery voltage to the #4 terminal of the clutch connector.
