I replaced the regulator for the blower, and all was fine.... for a day.
Now, after a few minutes the blower kicks down to low, and the SRS light comes on, and sometimes the ABS light too.

I figured it was the overvolt protection relay, and I put the one in from my parts car, same thing.

Any one have any ideas? does not seem to be keyswitch related. I tried the search, but didn't find anything helpful.
