Where is this located in the engine bay? I believe the car is giving off a hell of a lot of heat and the *** needs to be checked. I actually think its broken as from the inside (interior) when the temperature **** is turned it moves freely as if its not even connected.

 

no one knows where the heater/cooling temperature valve is located in the engine bay?

 

Heat/cool **** is electrical, not mechanical. A damper door gets moved electrically to allow/restrict air flow to heater core by the blower motor. That's why your **** feels so smooth. It's only allowing an electrical motor to position the damper door position. Hot water circulates all the time in the heater core.

There isn't any. The heater gets hot water all the time. They control temperature by controlling the amount of air that goes through the heater. Run the On Board Diagnostics and see what codes you get as you could have a problem with HVAC actuators that control the air flow.

Here is the diagnostic for the automatic air conditioning (assuming you have the automatic version):
Too Hot in Vehicle

Test Description
The numbers below refer to the step numbers on the diagnostic table.
2. This step clears the HVAC control module memory and checks for current air temperature actuator diagnostic trouble codes.
3. Ambient air temperature must be above 3°C (38°F) in order for this A/C Compressor test to be run.
7. The specified values are from the A/C System Performance Test

Step Action Values Yes No
Schematic Reference: HVAC Schematics
Connector End View Reference: HVAC Connector End Views
DEFINITION: The temperature cannot be adjusted, or the cooling is insufficient during A/C operation.
