97 intrepid climate control problem

I have a 1997 intrepid with the 3.3L engine. When I start the car everything works fine. When I put it in gear, it blows the fuse for the ac/heat. Nothing will work on the climate control center except the blower(which works like it should). Has anybody heard of this happening before? If so please help! Thank you.

Look on a wiring diagram to see what else is on that fuse.
