1997 CHEVY BLAZER: ALL THE DASH LIGHTS ARE OUT?

This answer was rated:

MY 1997 CHEVY BLAZER HAS NO POWER TO THE COIL. ALL THE DASH LIGHTS ARE OUT???? CANNOT FIGURE IT OUT?? ANY SUGGESTIONS??

Sounds like the ignition switch is out...do you have access to a voltmeter? We can test the voltage into the switch and out, to further confirm this. No power to the coil and no dash warning lamps are key indications of loss of power through the ignition switch, but it could also be a power interuption to the ignition switch. Also, check your positive battery cable, it's prone to loosening up slightly and causing a power loss.

Would that be part or all of the reason that it will not go out of park? The terminals are tight, already checked those.

Yes that would be related as well, the shift interlock also will not deactivate without ignition voltage. You need to be sure your battery is fully charged and the positive cable is on tight and not corroded...if that is good, chances are it's the ignition switch..the switch isn't too difficult to replace. You need to remove the lower steering column cover and there's a couple of smaller screws holding it in.
