BUICK RENDEZVOUS HEATER PROBLEM

2002 Buick Rendezvous • 103,000 miles

Heater blowing cool air, will not heat up. Full of water / coolant, but is still overheating. When it starts to run hot as temp rises I can turn the controller to heat/ cool (opposite of what it is on )and it will come back down, but still not blowing heat.
