i have an a/c that is stuck on and a radio that doesn't power on. anyone had to replace or fix this problem? any advice is helpful, thanks

 

you might need a new head unit or circuit board. Is your car still under warranty?

 

unhook the battery and hook it back up and it will reset the unit. it has happened to me 3 times in the past 2 years. i have a 03 g35 sedan w/ 90k on it. i use this method until i can replace the head unit completely w/ double din dvd

 

can you tell us what should we do exactly ????

cuz this happened with me today ????

 

if you have warranty have your dealer replace the head unit
