    I hope someone can shed some light on this for me. This weekend my cabin heater blower, all four power windows, my daytime running lights and my parking brake set indicator light on the instrument panel all quit working simultaneously. I can find no fuses blown, and I can't even imagine all those things would be one one circuit anyhow. Has anyone heard of something like this?

    Very strange, maybe a dead 12v battery?

    Never say never, but I would doubt rodent damage. It's my daily driver. Thanks for the response though, and I'll be sure and look for signs as I'm working.

    Yes, it still runs and drives, the mentioned components just aren't working.

    I agree ... very strange, indeed. The 12v seems fine, but later today I am going to check the voltage with a meter. Called my local dealership and they have no ideas.

    I'm going to check it later today with a meter. I've gotten no indicators for low voltage, though.
