So, I had a problem with the passenger side blowing hot air, While the settings are on a/c. This vehicle has dual climate control btw. Drivers side works fine. Back works fine. So, I did some research and obvious thing was the blend door actuator. So there are 3. 1 on driver's side, 2 on passenger side. From my research I discovered that the top passenger side was for changing from dash to floor. And the bottom one is for heat and cold. So, I got a new one and I changed out the bottom one. Walla! I now have a/c on passenger side. So, here is my problem.... I now have A/C, but no heat on passenger side. I had only heat, changed the part, now it's only air.. Any ideas? Did I need to adjust the white plastic thing the actuator goes on? Or do I need to replace another actuator?. Thanks in advance..

Did you reset the HVAC system after changing the actuator?

Search the forum for it. Use keywords "HVAC reset" or something similar. You'll find the procedure in several forum threads.

It can be done with a scantool, or without one using this procedure:
Important: Do not adjust any controls on the HVAC control module while the HVAC control module is self-calibrating. If interrupted, improper HVAC performance will result.

Alternate Method (w/o Scan Tool)

Clear all DTCs (diagnostic trouble codes).
Place the ignition switch to the OFF position.
Install the HVAC actuator.
Connect all previously disconnected components.
Remove the HVAC/ECAS fuse for a minimum of 10 seconds.
Install the HVAC/ECAS fuse.
Start the vehicle.
Wait 40 seconds for the HVAC control module to self-calibrate.
Verify that no DTCs have set as current DTCs.
