When turning vehicle off Radiator clutch fan will turn on automatically. When i do turn on my a/c the clutch fan does turn on and also when i turn it off it turns off. When the a/c clutch stay on i have to disconnect battery so battery won't drain.

Yep, this happens when the radiator cooling fan controller goes bad which is common with these cars, where is the location so you can swap it out to fix the problem. They call it a relay but it is a solid state controller. Check out the images (below). Please let us know what happens.
