Heater stuck on warm

[Decibel]

Got a issue

My heater is stuck on warm, doesnt matter what i put on the "knob", warm or cold, its just hot hot hot.

When i drive 70mph or faster, its getting really really hot under the steeringwheel, same on passenger side, need to stop and take a brake every 20 minutes
And this is with the fan at zero, if i put it on 1 or higher its the same thing, but from the dashboard and where the heat is supposed to come from.

Have read something about a heat-valve, where is this located?
Can it be the electronics in the dash ?

Sorry for my english, im from sweden

sounds like balend door is stuck. if you push in the recirculation button, it will remove any incoming air from the engine compartment. this will reduce hot air under dash. i believe the actuator motor is above and to the right of the gas pedal. check to see if it move while you change ac/heat cotrol position.

Where can i find this door ?
Under the dash or under the hood ?

this is in the car under the dash. i controls the direction of air flow based on the position that the controller(dash knobs) is put on. i believe the motor for the blend door is monted just above and to the right of the gas pedal.
