Hi I'm experiencing some problems with my heater system for 2005 Honda Accord Coupe V-6.
The heater in the middle won't turn on when I try both Auto and Dual mode. The heater from the passenger and the driver side works well but the 2 in the middle fan don't work. It's like the back people won't get heat since the middle fan won't blow
Btw, the AC works fine on all of them.

I'm afraid there's something wrong with the fan in the middle since it won't blow heater, only AC. Also, the 2 fans in the middle don't have the thing you can adjust/block the air from coming too much...... The two fan from the driver and passenger side have it though.

I'm not exactly sure if you guys know what I mean. Please help.

Also, what's the use to turn on Auto AND Dual at the same time?

 

Is your system digital or manual??
Maybe one of the doors is stuck shut. Had the same prob. on my 05 taho. Had to change out the whole gauge cluster...but that's chevy whole another deal. I don't think honda ties all there electrical stuff into their gauge clusters.
