I see this question time and time again and 95% of the time, there is nothing at all wrong. These fans aren't programmed to come on until very high temps. It is a 2 speed system and low speed doesn't come on until about 225 degrees. That may seem to hot but it is not and this is the way it was designed to run.

Will the pcm give a code if its a problem with the computer...because the car is running fine except the fans not coming on? Will it show other sign that the pcm is not working proberly.....

There is nothing wrong with your computer. You have proven that the computer has control of the fans because they come on with the A/C. I doubt there is anything wrong.
