The A/C started to blow only heater air and the coolant light was on. Found that heater control valve was rusty and leaking coolant, I replaced the heater control valve and no more leaks but the a/c is only working on heater. I clamped the heater hose and the a/c is working great but not the heater of course. How can I fix the problem.
