I have a 2010 VW Tiguan that yesterday started to produce heat only on the driver side. It blows air on the passenger side but no heat. VW does offer zone heating but my car doesn't have that option.

There is a blend door actuator switch that may be faulty.

I have same problem too

Did you guys figure out the solution? I have the same problem on my 2010 tiguan

i also have that problem

Hey Ken, I just changed my heater core a few weeks ago and it fixed the issue.

Got my heater core flushed. Cost 200 bucks but probably save a thousand getting the core changed. Heat works great now. On both sides. Before it only worked on drivers side. So pretty easy and cheap fix considering.

Thanks man, fortunately my friend is a mechanic and he changed my heater core for $250. When I took it into volkswagen they said I have to replace my entire heating system for $2000..lmao..useless

Are you in Ontario, Canada by chance - my mechanic has said it will cost around $700. Thanks,
