I need help with this code P0646 A/C Clutch Relay Control Circuit Low
The dsc light is on and won't go off and the a/c is blowing hot air How do i correct this issue?

 

sounds like you might have a leak, try topping of your 134 see if that fixes the ac hot air issue. As for the DSC that sounds like a seprate prob.

 

The a/c was blowing cold before the dsc light came on. I drove the car hard and next thing i see the dsc light on constantly. Then tried to use a/c and it was blowing hot. Before i blew the dme it did the same thing.
