I have a 1997 Chevy Blazer and this happened sometime ago and the problem returned. I put the key in and no lights come on the dashboard at all it corrected itsself but now it won't start at all. What are some of the possibilities for problems.

Any help is appreciated
Thanks the poo

Rick Norwood did a post on that. Something about a loose 20 amp fuse in the dash fuse panel.

'97 Blazer, no cluster lights?.

Ignition switch is bad.
Do a search on it. It's a well documented problem on this year truck.
