I'm having an issue with the pass side blowing cool. everyone seems to say HEATER CORE. However my '12 SE Passat is not covered under the extended warranty (however VWoA is willing to cover it IF that is my issue). I need to be certain my heater core is the culprit before i drop it by the dealer for official diagnosis. What are the tell tale signs for diagnosing this? How can i actuate the blend door so i can verify it's working properly? Ive searched the youtubes and on here and can't seem to find a good thread with pics. If you know of one please shoot me the link. thanks.
