This is my first blazer and my first car and i know that the year is 1996 but i dont know if its a s-10 , ls or any thing and its a for door and i looked at pics and s-10 are pick ups and people talk about the ls and on the door it says lt and i dont know what kind it is so can you help

Any mid-size Blazer is on the S10 platform. Blazers in 2-door and full-size trim will look like Silverados of the same age.
LS and LT are just trim packages. Usually the LT is fancier than the LS in some respects. LT just means it has the "Luxury Trim" package and will have some minor cosmetic, but not structural differences.
The LS means "Luxury Sport" and usually had less trim and power options, but had a "touring suspension" which featured Bilstein shock absorbers and wider and slightly taller tires from the factory.
