Time for a 30 amp fuse

(I am kidding, don't try it and make the situation worse by smoking a BCM or melting down the wiring harness or setting her ablaze...) In all seriousness I wouldn't know where to start on this one...ABS module and the HVAC control panel swap maybe...but that's a pricey "try it out" option.

You know - I wonder if age is just getting to it and if you're blowing the fuse with 11 or 12 amps and nothing's really dead-shorted or anything. You could bridge it with an ammeter and see what the draw is - this might be fixed with a 12 or 15 amp fuse, which should still blow long before any wires are going to get hot. A 30 amp fuse is way too high, but a 12 or 15 would be a different issue and might be an idea.

Yeah, I was thinking about upping the fuse but was a little leery about that. I'll put the ampmeter it and see what happens. Thanks.
