Where can I get a wiring diagram for a ignition switch harness for a 2000 blazer? I would like to check my switch with a meter before I rip the column totally apart. thanks

 

Sorry for the slow response time. Forum problems at the beginning of the year meant a lot of new posts got missed. I do hope that you have cured your problem by now, if not, see below.

I think this should cover what you are looking for:

I have an ignition switch another member sent to me that I was going to trace out, then disassemble and see how it worked.
