2005 inf.G35August 16, 2015August 18, 2015My inf.g35 runs hot sitting still when the air condition is on Keywords:G35 1 thought on “2005 inf.G35” Freeautomechanic August 18, 2015 at 9:52 am Check your high speed fan to make sure it is coming on when you turn on the Air Conditioning. If it is not(which is what i suspect) you will need to test the fan and the high speed fan relay. There are 3 cooling fan relays and 2 fan motors. If you have no power to the relays, check the fuses.
