Since my post, the blower stopped completely.

I checked the fuses, but they all seem OK. BTW, there is no specific marking as to the blower motor fuse per se. I checked the obvious ones, but maybe missed the right one.

I checked with a second repair shop. They too advised that you don't just swap out the regulator. The reasoning being that the blower motor causes the regulator to fail.

All the replies seem to discount that.

What am I missing here?
