I have a 2007 G35 Sedan with an heating issue. The heater blower comes on intermittently even when the display on dash shows to be on. Sometimes it works after turning off and then on. I called the Infiniti Dealer today and they said the problem lies in my radio which controls the a/c and heat and they can fix for 565.00, I also did a search on this side that also identified the issue in the heater blower relay that's about 40 at the dealer.

Any ides would be appreciated,

Lee
