Stupid question for most I am sure, but I have a 96 blazer that will not start. I am guessing its the battery or the alternator..... The lights will come on but are VERY dim and there is an odd LOUD clicking noise when I try to turn it over.

If anyone can narrow the field I would GREATLY appreciate it!

I would start by charging the battery then if its still not starting then I would say CHANGE the battery. if it was running fine and now just wont turn over, then it's most likely the alternator. CHANGE THAT and it should work....

I had a '98 lumina that had a bad alternator and I experienced a similar problem.

good luck!
