I must admit that I did not expect to be posting here because I figured I 100% figured out the issue, guess not.
I recently purchased a 2014 Volkswagen Passat TDI SEL Premium in June, it has ran perfectly fine and no issues up until I went to use my heat. With the heat on full blast and the vehicle up to operating temperature I got no heat. However, if I would rev the car up while stopped or accelerated quickly, I would get a short burst of hot air, only for it to return back to being ice cold.
I consulted my friend who is a mechanic and he said that he is 99% certain that it is a clogged heater core, and after doing some research, it seemed like a pretty common issue. I ordered the part and spent what felt like an eternity installing it. Turning on the heat again I was met with ice cold air, no heat at all. I measured the temperature of both heater hoses coming in and out of the firewall and they were both at a decent 120-130. Coming into the cabin of the car, I felt the bottom pipe of the heater core, super hot, almost too hot to the touch. I felt the top one, ice cold, this is where I am stumped.
What I assume is that the issue lies in the blend door actuator, because it is near the lines on the interior which would explain the normal hoses in the engine bay and the one cold/hot one on the heater core itself. That's why I wanted to post here to see what everyone thought, i'm sure there are plenty of people here way more knowledgeable on these amazing cars than me.
Let me know what y'all think! Thanks in advance..
