I have a 2010 1500 Laramie with the dual zone climate control. My air has been blowing very weak pretty much since I got the truck back in 2020. I have been having issues with the blend door below the radio (not sure what number it is, I believe there's 4 blend doors in the air box). The blend door below the radio would sound like a machine gun for a few seconds after starting the truck and a couple months ago it finally stopped. Now my defrost won't work anymore.
I scanned for codes and got a B109E (panel mode door 2 control circuit open) and B1058 (recirculation door control circuit/performance) BCM codes. I took my fan out and verified that the recirculation/fresh door worked as it should. There were no blockages and the evaporator core looked good from what I could see. Turned the fan on while it was out and I was holding it and it made plenty of air. I asked a guy at work that used to work at a dodge dealership and he said its a bad blend door.
Is there anything else I should check before ripping the whole dash out for a blend door?
Since I'm sure there's no way around tearing out the dash and air box is there any preventative maintenance I should do while I'm in there (replace all blend doors/actuators or something along those lines)?
I'm assuming all the blend doors in the box are the same and I won't have to worry about different part numbers or anything.
