The control head is a plug-in part. Access it by carefully prying off the plastic trim around the climate control and radio. The trim snaps on in several places. You may find control heads in junkyards, but most have the same problem with the hot on one side/cold on the other that is discussed frequently on this board. New ones aren't much better. I replaced mine under warranty at the dealer, and it was worse than the original, so I had them reinstall the old one. The issue is a design flaw with the controller and temp sensors.

What is causing your car to run hot when the thermostat has been changed?
If your heater isn't blowing any hot air when you turn it on and set it to hot, most likely the thermostat is faulty. It is also possible that you have an air bubble in the system (bleed it), the radiator is plugged (replace it), or the water pump is bad (replace it). As far as using the heater to test the system, that is sometimes unreliable because either the lines to the heater core are plugged or the control valve in those lines is jammed.
