Heater problem
2003 Buick Rendezvous Four Wheel Drive Automatic

the heater switch is turned to hot but there is no heat coming. Air is blowing so the blower motor is not bad, but there is no heat.

Hi:
This can be caused by a few things. First, with thngine hot, running and the heater on, check to see if both heater core hoses are hot. Also, make sure the coolant level is full.

Let me know what you find.
