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..
