A/C TURNS TO HEATER?

1998 GMC Sonoma

Air Conditioning problem
1998 GMC Sonoma 4 cyl Two Wheel Drive Manual 160000 miles

I have a 1998 GMC Sonoma 4 cyl 5 speed and ever time I turn on my a/c it will blow out HOTT air and the floor board dose the same thing. The wierd thing is when I turn the switch off it and is still blows out hott air under the floor board.
