blend actuator is mostly bad,resetting will only set but it will still resets itself upon every pwr up and will do so until actuator is repl
where is blend actuator located, an do i have to take entire dash loose, also can this lead to a vaccum leak
there are 3 so determine which is bad and locate it. 2 are easy and 1 is a 5 hr job.good luck
can you send me a picture of where those 3 blend actuator are located.
