no heat
Let me first say this started with no a/c but had heat during the summer, now its reverse. During the summer I was getting heat out the passenger side when a/c was on so I pulled dash out and did the gear fix on both actuators. Well it fixed the hot air problem on the passenger side but couldnt get cold air out of the driver side so I opened blend door and took left actuator out and didnt have any problems.
Now the cold weather has come and its a bit chilly and now my damn heat doesnt work, remind you I have no actuator on driver side air box. I pulled the codes for manual diagnostics and got B0363 and 0441. Would these codes cause a no heat situation or is it something else like the hvac unit? I turn the **** slowly to adjust the heat so its not that and sometimes I have a difficult time changing fan speed so Im kind of at a loss as to why the heat wont work.

So you took the actuator out, but had the blend door set so that it blew cold air in? Why not just turn the blend door so it blows the heat in? If there is no actuator how would it switch from hot to cold as that is what is happening when you are turning the temp ****? You may be turning it, but nothing is going to happen on the drivers side without the actuator in, and with no actuator, I would assume you would get these codes as well.
You just need to fix the actuator, get a new one, or try to move the blend door until you can get a fix.

Just the answer I needed, I was over thinking things as usual. Im going to try and turn the blend door manually and hope I can get some heat until I can get a new actuator. Again thank you dmarkshark.
