I am now getting this problem, but ONLY WITH THE A/C ON.

As posted above, is this a "low charging"/battery problem? It literally ONLY happens on decent drives with A/C ON. It has never happened, and still does not happen if the A/C is off. I have the original battery but have never had a problem with cold starts, or starting the car after sitting up to a week. However, now that I think about it, the A/C blower seems to fade in and out at anything over half power.

Thanks,
Steve
