it might be cycling the ac, turning on the aux fan for cooling when you're over temp, or like mentioned, running the heater, putting a momentary extra load on the alternator

My 99 does the same thing...saw a TSB on it but unless it's under warranty, the dealer won't do it for free!

Could also be a loose belt, or worn out head light switch.

I doubt it, a loose belt would make noise, it wouldn't just slip and not make any noise!

I stand corrected and take back what I said before. However, I still believe that the TSB is related to his problem. But yeah, change the belt if it's squeaking!

I agree, the loose belt is probably just making the TSB issue more obvious! It is probably both.
