Hello i am having problems with my heat, it only bows hot on the drivers side and not on teh passenger side. I have looked up this topic and have replaced the heat a/c actuator on the passenger side with a brand new one and that didnt fix the problem. Is their anyone who has had experience with this problem that can share a solution with everyone?

 

i have the same problem. At the driver side heat work but the passenger side heat don. t work, flush cold air... Blend door switch work.

 

You may need to remove the glove box to see the duct work. From there you might be able to feel where there is heat and where there is cold.
Depending on what controls the duct work doors may provide you with the cause.

 

I verified this problem tomorrow. This duct position behind cabun filter? in behind the glove box is a actuator blend door? On hyundai sonata nf can reset hvac? Reset or diagnosis? .
Update : I diagnose hvac, don. t have error 00 code normal. I try reset hvac and learn but i don. t know... try tu pull a 10 fuse hvac in put after 1 minute but don.t work.
