I have a 2002 Buick Le Sabre custom with 36,000 miles on it and the temp switch will not allow any heat to come out into the car.

Asked by Apr 28, 2014 at 04:38 PM about the 2002 Buick LeSabre Custom

Question type: Maintenance & Repair

I can slide the temperature lever back and forth but it will not allow heated air to enter the car.  Bothe heater core hoses are real warm,  the temperature gage reads 189 degrees when warmed up.  Radiator is full of 50/50 anti-freeze,  with coolant in the coolant reservoir at the correct mark.

could either be a valve corroded shut running to the heater matrix or a major air blockage try raising the front end and re bleed off the system if that doesn't sort it look where the two pipes run into the fire wall there will be a valve there controlling the flow that may have to be replaced
