Hello I have a 2008 VHD with the auto climate control. I have had two codes come up and it is interfereing with the heater controls. First code is heat exchanger temp sensor elec fault mid146 sid 13 fmi13. The second code is cabin temp sensor elec fault mid146 pid 170 fmi 13. I have both new sensors just wondering if any one can tell me there location. I'm going to assume they will be in the heater box area with blower motor and evap but just a guess. Any help is appreciated.
