If you have a Hyundai Sonata or Elantra and the AC unit or the internal AC switch sometimes turns off and sometimes turns on, for example, if you park it in the sun it works, and if you park it in the shade it doesn't work, and the electricity disconnects randomly, I have the solution. I can repair the part you have instead of buying a used or new part at a good price. ( Phone number appears when clicking the contact button )
