My air conditioner, cruise control and horn all went out at the same time. I brought my car to Auto Zone and had them put it on their machine but it showed nothing. I also brought it to a mechanic shop but they claimed they saw no burnt fuses. Any idea what my problem is and an approximate cost to have it repaired? Thanks so much for your time and help!! :)))

It could be many things. If the fuses are all good, then I would recommend checking the body grounds on the vehicle. If they are good, suspect an issue with the body control module (BCM).
