    Hi I’m back again. I just went through replacing the crank sensor and cam sensor as well as new cap and rotor. Truck is running great but, always a but, I now have no heat. Is the blend door vacuum operated and could I have knocked a vac line loose when working blindly on the cap/ rotor or cam sensor? I am at work and do not have my dodge manual with me. Thanks in advance.

    If you had heat before then more than likely a vacuum came loose. Look at the back of the engine on the right side for a loose hose. You might hear some whistling at the connection port.

    Yes you absolutely could have. There is a vacuum tee by the firewall on the passenger side of the intake with a check valve in it. When disconnected it should default to defrost only.
