If you’re experiencing a hissing sound coming from your car AC, it may be because of the air conditioning unit. Here are some tips to fix the issue:

  1. Check to see if the air conditioning unit is working properly. If it’s not, you may need to replace it.
  2. Check to see if there is a problem with the filters. If they’re not clean, they may be causing the hissing sound.
  3. Check to see if there is something blocking the vents in your car AC unit. This could be a piece of furniture, a rock or even your child’s toy! If this is the case, remove it and try again later when everything is back in place.
  4. Make sure that all of your cords are properly plugged in and that nothing is blocking any of them from reaching the AC unit or your device!
