try pulling your hvac fuse for rear with key on for 60 seconds first it may reset the actuator if not the acturator may not be working. it will take another minute after you pull the fuse. the fuse is in under dash fuse block. it may reset fronts as well. if not that it will have to be scaned to see what is wrong
