Cab Heat

[frodmiller]

2015 Charleston RB. Has anyone had trouble getting heat from the cab heater. Mine runs cold even though the engine temp is 187. AC works fine.

While I don't have a clue about your unit, I have to ask if it has heater shutoff valves and are they open? Easy way to tell is feel the heater hoses and see if they are warm or cold. If warm, the other issue may be the modulator valve on the inlet side of the heater (on the firewall). It's usually cable or vacuum operated and needs to be open for the heater core to receive hot coolant and thus produce heat... The modulator valve is there to prevent the heater from fighting the ac during warm weather.

No issues with mine, but I have to have it set to maximum heat to get heat.

That should not be. You might want to look at your modulation valve. They are adjustable.
