ml heater
i have a 2001 ml430. the heater blow very hot thru the dash vents. if the heat dial is reduced the air cools thru the floor vent but continues hot thru the vents. it takes a long time to cool thru the vents.
sometime it is soo hot the vent do not cool. do i have to turn on the a/c to cool the vents. is there a control seperate for the dash that should be checked? thanks, sh

I doubt heater core, usually the only thing a heater core "does" if it fails is to leak. Or else gets plugged up somehow. Doesn't sound like that either.
There is no heater valve on an ML, so it's not that. Everything is done with flaps, so maybe a problem there, or a sensor or feedback actuator. Could also be either the interior temp sensor, or the hose which draws air through the temp sensor has fallen off, or the sensor is just very dirty.' Gut reation is that this is just another "general" complaint of the ML heating system which caused the system to be redesigned in 2002. I never liked the way the pre-2002 system reacted, especially in very cold conditions, and the present system in our 2003 roadside truck I'm not sure is a huge improvement, although I have yet to drive it in verd cold weather (we never had a 2002 roadside truck, went from a 2001 to a 2003).
