My AC/Heat is working for the driver/passenger side plus the back. The only two center vents are not working. I can hear the blower or fan being on but itseems like it's been restricted of air circulating out into the vehicle. I change out the cabin air filter already. Not sure if it's the door activator issue. I don't think it's an blend motor issue because I don't hear any grinding or loud noice.
It's most likely a blend door or blend motor issue since that's what controls the air flow through the HVAC system. Do you have air flowing out the defrost on the top of the dash or heat vents under the dash?
Yes, there is air flow through the dash vents and under the dash it comes out AC/heat. There's just no air flow through the two middle vents. This is a 2011 Pilot EX FWD and the the air flow on the highest setting the flow is not that strong. I know this is an automatic HVAC climate control system. It's plenty much a headache. I wish it was a manual HVAC system.
