What will cause battery power drain on a 1997 Chevy Blazer S10 LT 4x4?

This requires a very basic trouble shoot:
As you have not specified a period that the battery goes dead I will speak generally.
- Charge and then disconnect the battery for the usual amount of time it takes to go dead. If the battery is dead the battery is faulty.
You need a way to measure draw. 100 Milli amps is considered normal. (1/10 of an amp)
An ammeter works best but it will need to handle 50 amps or more and accurate to 10 Milli amp.
A test light will work for large fast draws.
- Start by measuring your draw, A fast or large draw will cause a test light wired between the positive battery terminal and positive cable.
- Start removing the fuses and see when the draw reduces or goes away. What was it powering?
Good Luck

I ran out of time on Saturday to do it, but it looks like you remove the battery. Then you can reach down and open the drain plug. It is just below the battery at the bottom of the radiator.

its on the left hand side of the radiator but not very easy to get to My apology, it is a 1996 S10 Chevy Blazer instead of a 1999 Chevy Blazer. I need to see a picture or more detail of where the drain plug is located on the left side of the radiator. I have searched and searched and cannot find anything to drain with. Thanks, Linel
