Electrical problem, I think.

Yup... with 100K on it, I figure it was due
anyway. I wasn't about to pull it out and
just replace the VR and put it back in.
I got a rebuilt Delco from gmpartsdirect.com
and it went right in.

The fella I talked to at my local service center said they would have to replace the whole alt, and when I specified if just the regulartor could be replaced, he said no, he'd have to replace the whole alternator...

Perhaps the 01's are a bit different?

Thanks for the help again... sorry to hijack threads

Most shops don't want to rip apart
an alternator to change the
regulator. It would be something you
do when you rebuild it. They know the
same thing I said earlier. The labor cost
is significant enough to get the alternator
out and back in. The cost of a rebuilt
AC-Delco alternator is not too bad.
For my 1995, its $132. The voltage
regulator is $43. You might as well go
with a rebuilt, because they replace the
bearings.
