Unhappy ml320 whinning sound- cold start???

Help!!!2003 ML 320 --When I first start the auto and if it's cold- 30 degrees or lower it make a high pitched whinning sound that only last a few seconds up to a few minutes then goes away. Makes the sound with or with out the heater turned on. Sound seems to be coming from dashboard in front of driverside, maybe in front of firewall --don't know.
