The AC Push buttons are unrelated to Fuse #8.
With the Ignition off the Buttons should stay pushed in.

You have two separate problems. Your PBU (push button unit) is faulty, along
with the fuse problem.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
