Take the blazer to a local autozone to have the battery tested for FREE! but the blazer would not start if it sat for a couple days or so. also it would start hard, but once it started it would run fine.
Have the battery and/or starter tested for free at your local auto parts store.
I would recommend 500 minimum.
You have a problem with the charging system, probably a bad alternator.
Yes
Blazer does not take off like it should. sluggih slow take off then after it gets going it does wee.
yes, 82-93 are the same besides grill design
the 1996 and 1997 are the same and would not work in your 2000 straight from GM
It could also be a corroded connection, the fusable link or the keyswitch.
That would be the 4L60E
Have the battery load tested at your local auto parts store, even though you think you have it charged it may be bad. Have the charging system tested also.
A Chevy K5 Blazer can be purchased at many different locations including Chevy dealerships. Another option would be in sites such as eBay and Craigslist where one can find listings from individuals.
Yah it will
