When you turn on the ac do your engine fans cone on ??
The ac should not be affected by that fuse issue you have , if those engine fans are coming on high speed when you turn the ac on then the ac compressor should come on , the signal to the compressor is pulse width modulated how are you checking the signal there ?
When he ac is turned on the ac fans should come on high , how are you checking the freon levels ??
They should come on high speed you may have a issue with the fans control module located under the battery tray causing the issue where its also draining the battery i recommend you check this . I hope this helps. Please dont forget to provide positive feedback for the help provided thank you
