As you say that these parts have already changed, Chekea in which the butterfly sensor is located, many times by low voltage the box can enter into failure mode, that would be consistent with what you say that with the A/C the fault is increased. Luck !!
Hello friend how are you!? I have an automatic 1.5 wool and presents that same fault and I imagine that your Hbaras discovered what it is. You could tell me if you releasing it and in case. How did you do it? I await your prompt response
Brother I would like to know if you could solve the problem in your wool box and how you did, since I also have the same problem I wait for your prompt response!
