the rear vents blow when the knob is set to the center vents. problem is there r 4 center vents on the dash then those vents way in the back. if u close some of the center vents airflow should increase in the rear.
Hemilancer is right. If you close the 2 center dash vents the airflow increases to the rear vents...Not much but it does make a difference. Drove my sister-in-law to the airport this morning and adjusted my vents as described and we were all very comfortable. It was 16 degrees this morning.
I had the same thing. I pulled the console and installed a small blower/fan right at the vent. Only problem with it is it's one speed so it blows the same amount of air no matter what. If someone is back there and gets too hot or cold they just close/open the vents in the console. Wish it had a factory set up thats for sure.
I noticed the weak flow. I had the recall addressed on Friday. I am sorry to report that after the recall HVAC issue was taken care of, there was still no change in the air flow. I imagine it's an engineering defect that we will all have to live with.
