Asked by for the 1996 Chevrolet Blazer
Poor connection for the dash ground. No i don't know where it is. Back a few
years it was just above the park brake pedal 10mm socket to tighten, but on this one
i do not know. This is one scenario, more possible.

Unlikely. Have you had the battery and charging system checked by a shop(not a parts house)?
Highly unlikely...
