I have a 2009 RDX. My heater is not blowing hot air even though everything working fine. I have looked around and it seems like my inlet blend door actuator is not working and needs to be replaced. Do you know where it is located on my model? I don't really want to take apart my dash looking for it. I know where the driver and passenger blend door actuators are, but if anyone could point me in the right direction. I would appreciate it.

The one I am trying to find is the main unit / air inlet recirculating (blower housing) actuator.

 

Heater core piping look for leaks if at all possible.

Whole system check for leaks, sticking points, blockages, rattling, or squeaking if at all possible.

Blower check for worn bearings if at all possible.

 

Thanks. Now that I found it. I am a unsure how to get it out. The actuator is all the way to the side of the passenger side wall. There is little room to get your hand or a wrench to all four fasteners. What is the best why to remove it?

 

Can you take a picture and I'll see what tool would possibly fit to remove the fasteners?

 

It's a tight fit. I can get to two of the fasteners but the one on the top it can't get a straight enough angle for my open ended wrench. The is not enough clearance for a socket because there is a box less than an inch away. The actuator is connected to the green plug. The steel bar on the right angle over just enough where I can't get my wrench to lock on.

 

Take a look at this maybe it will help in removal
