My a/c heat rear distribution was making a clicking noise and not blowing out air in the front then after so long it finally stopped blowing in the back too. You can hear the air blowing but nothing is coming out. So removed it but now notice that the clicking noise has continued but not as loud as before, does this mean I also need to replace the temp blend door actuator? too, I'm not having problems with hot or cold. But not sure why the clicking has continued.
