Re: A/C, Radio, Arrrrrg!

Well it appears that this TSB doesn't apply to my car, but I've got the
wiring diagrams from the Alldata CD and (though they aren't really all
that helpful) I'm going to see if this looks feasible.
I also am going to try to put on a power conditioner sort of apparatus
that I've got plans for, to see if maybe that will help (for the stereo,
anyway).

Thanks
