So I went through the whole process of replacing the broken blend door. After putting it all back together The actuator was working. However the teeth it would not align with the blend door. I did the calibration procedure to no avail. So I took the actuator apart lined up the teeth and put it in. it worked fine 2 or 3 times then nothing. I figured I screwed up something when I took the actuator apart. So I bought a new one. Put it in and nothing. Took it out and bench tested the actuator and it works fine. Has the temperature control switch gone bad? Checked all fuses. If I manually move the blend door according to the heat or cold air setting everything seems to be correct. Help!
