hello my name is Jason i have just recently bought a 2008 D40 dual cab and just this weekend gone the heater has stopped heating in the cab, took it back to the dealer i bought it off and they tell me the control fuctions on the heater are broken. Iv'e been told the that the unit will need to ne replaced and total cost will be $1000 (dealer special). having had a BA falcon in the past with a heat mixer problem I know whats involved but i do feel the price is abit steep? has anyone had this issue bfefore and has there been a cheaper outcome?
