I JUST HAD THERMOSTAT AND RADATOR CHANGED RIGHT AFTER THEY WERE CHANGED MY THE CLIMATE CONTROL KNOB FOR HOT/COLD WILL NOT TURN AND WHEN I TURN IT ON THE AC CAME ON. THE KNOB IS TURNED TO HOT, BUT COLD AIR IS COMING OUT. BY CHANGING OUT THE THERM. AND RAD. WOU LD THAT MAY HAVE CAUSED THIS PROBLEM?

It shouldn't change anything. The climate system is fairly independent of the radiator and the thermostat. The 'hot/cold' knob is connected to a butterfly-type of valve that 'chooses' whether more air comes from the environment or through the engine heating core.

I would have them look at this, and I would inform them that the knob operation changed after repair. I would be surprised if a fix was expensive or required new parts. Hope all goes well.
