Heater not blowing hot air driver's side after car has warmed up

Hello,

This could be a problem with your vehicle's heater control assembly. In the diagrams down below I have included the instructions from the vehicle manufacturer on the removal and installation of your vehicles HVAC Unit. Please go through this guide and get back to us with what you are able to find out.

Thanks,

If I can add this happens when the blend door actuator cable goes bad here is a guide in the diagrams below to help walk you through the steps.

After disconnecting the heater/cooler unit side connections of the air mix damper lever cable and air outlet changeover link cable, remove the heater control assembly.

Insert a flat-tipped screwdriver into the control base clip from inner side, and then remove the cable by lifting the claw part of the clip.
