Start by checking the ground wire. There's a wire on the passengers side rear of the engine block that tends to go bad and create some kind of crazy issues. Copy and paste the following youtube link to get a better idea of what i'm talking about. https://www.youtube.com/watch?v=lETfny-Xy4c

I'm glad you've solved your issue. I will say that removing an airbag fuse could be a bad idea (Lack of airbags). Obviously, you likely know that already. I would still recommend checking the ground wire. Removing one item from the circuit could improve the ground being shared by your other devices (over time, a failing ground could leave you stranded or worse) Just keep in mind the possibility and if any other issues arise, give it a look-see.
