Hey everyone I'm new to this forum and I'm here because unfortunately my blazer failed on me last night in several ways. If this post is in the wrong forum sorry about that, and if so someone please point me towards the right one.

Well anyways, last night I get in my blazer and go to crank it it up, when I do everything electrical comes on as normal but my radio and climate control were both totally dead. On top of that the engine wont crank up and just rolls over repeatedly trying to start. Does anyone have any idea what might be going on? Thanks in advance to anyone who can add their two cents.

 

When you turn the ignition switch, there are several contacts that move and connect several different circuits. Fairly common for the contacts to burn and not make a good connection. Best to have a schematic to check each circuit, in each position of the ignition switch while turning it. This link explains: https://blazerforum.com/forum/articl...-switch-33465/
