A/C Operation

My A/C is blowing hot now. It all started when the driver's side started to blow warm. At times
it use to go back to cold after driving for awhile. Just on the driver's side. Now the passenger side is blowing warm. I went under the
hood & found the valve for the low side line.
But where's the valve for the high side?

There is no low side valve as far as I know, check my sig for a procedure. About $100 or so to have somebody evacuate it and charge it.
