The heat works fine then fmip it to AC and it bliws nouthing but hot air and turn it all off and hot air still comes out ...is it the servo motor?

Same thing is happening to me it blows hot air no matter what , so it was the servo motor ? 

After a stop I accelerate and the breaks grab and it takes a few trys to get them to let go I have replaced the rotors , breaks and hoses , calipers , cv shafts but it still does it , the abs light comes on when it happens and the break light its randomand does not happen all the time ....please help
