heater blows hot at standstill but gets colder the faster you drive. better temperature on recirculate but still gets cooler as you are driving.

Hello,

This does sound like a problem with your vehicle's air inlet door actuator. When the actuator, which is a little plastic servo or motor, fails, the air inlet door will be stuck in whatever position the door is when the actuator fails. In the diagrams down below I have included the instructions for the removal and installation of the air inlet door actuator. Please go through this guide and get back to us with how everything goes.

Thanks,
Alex
