Its that time of year when I have just started to need to defog my windshield. I purchased a '14 Jetta TDI in July 2021 with just under 90k on it, after retiring my '02 with 354K on it (I am still sad about this, but a girl only has so many hours in a week to work on her car). I noticed the radiator fan running fast (start up to shut off--but not after shut off) as well as the driver side only defogging in the morning. I had to run the heat on my way to work Friday morning and only had heat on the farthest left vent, decreasing as you move to the passenger side. From my research, I see that a common failure in the Passat TDIs of this year is a heater core failure with symptoms similar to mine (I have not been able to confirm that the radiator fan speed is high in these forums). The Passat has a TSB for the heater core--but I cannot find one for the Jetta. Has anyone had this problem with their jetta? Is there a tsb for Jettas? just looking for any insight or help.. thanks!
Update: I appear to have a draining battery as well.. seem to have started at about the same time--noticed a slow start 2 weeks ago when i also noticed no heat... attributed the start time to the heat but have since had a dead battery and longer start time after sitting.
