I was charging my a/c today was charging fine, and then it stopped now the a/c light on the button only come on when the fan switch is off. no a/c when you turn the fan on and the air only blows out the foot vents. I do have temp control anybody out there with some ideas thanks

Did you evacuate the system first? What are your hi/low pressures?

I did evac the system I fear the low pressure jumper may have gone to ground and caused a short no fuses are burnt but it doesn't work right. Is it possible to burn the circuit board in the dash by going to ground?

Sounds like the A/C control head went out on you, VERY common problem. Unfortunately it isn't a cheap fix. There is a write up out there on how to try and save them by adding in a relay, and replacing the blower motor switch. Don't know where the link is at right now.
