Have 2004 dodge intrepid. Ac has always been ice cold. Now just blowing slightly cool and have noticed a "gasping sound" coming from behind ac controls. I recently replaced cooling fan units and a couple months later the ac is not working good. FAns are working. Some one told me it might be a vacum leak on the device that controls the "doors" to mix the air. I had the system check and there were no leaks. I live in AZ and it starting to get warmer.
ANY HELP THANKS

I also read something about pulling a fuse for 15 min and that will recalibrate the blending door cotroller
