I have no heat in the car. Engine temperature is fine, gets up to operating temperature and still no heat. Car goes through all the different modes and different fan speeds, but doesn't produce any heat. No coolant smell or anything of that nature. So I'm guessing it's my left main blend door or blend door actuator? There's other blend doors, but that seems to be the correct one.

Hello,

In the diagrams down below I have included the instructions from the vehicle manufacturer for the removal of the air mix control servo actuator for your vehicle. He installation is the opposite of the removal instructions. Please go through this guide and get back to us with how everything turns out.

Thanks,
Alex

I appreciate the response. This looks like an nightmare and paying a shop would be ridiculously expensive.

Hello again,

Yes, heater cores can be a bear to tackle, and as far as they go, this did look extremely complicated and time consuming to replace, even by heater core replace standards. In the diagrams down below I have included the labor rate time that a shop will charge you for this job. To find the total labor price, just multiply by the shop rate hourly charge where you live.

Thanks,
Alex

Just FYI for anybody else with the same issue. So I took the vehicle to the dealership. The no heat issue was only on the driver's side, so they diagnosed it as the driver's side air mix servo actuator. Apparently, the driver's side is far easier than the passenger side to replace. It doesn't require tearing the whole dash apart. Bill from the dealership is $550.00 for parts and 2.5 hours of labor.
