Thanks for all the help
Sorry to respond after you fixed it, but the slow cranking is exactly what mine did before the starter died completely. It was sort of funny how it went though, it was fine, then all of then overnight it was slow for a week or so, and just before I ordered a new one, I got stranded. No hard starts/no starts, just seemed to take longer than normal to turn over. Someone who didnt drive the blazer everyday most likely wouldn't know it. Fortunately it wasnt far from the house. But anyone with a slow crank and decent battery needs to swap the starter. I had about 140k on mine when it died. Or at least pull the starter and get it tested. Mine didnt want to spin even on a test stand. Just plain dead. Solenoid was good and would "click".
