I've had similar problems with my cables moving on the outside rather than inside the sheething. It's really common on first gens, or atleast it's happened to every one I've had. I've actually had to ban passengers from touching any heater controls, but inevitably somebody plays with one and I get stuck trying to fix it. It's how I ended up with cold air blowing in under the dash in the middle of winter
