Also, can anyone tell us where to find the heater sensor on 2003 Buick LeSabre Custom?
No heat in the car; heater comes on but blows out cold air. Heater core, thermostat, etc. have been checked and appear to be o.k. Want to check the sensor, but cannot locate it. Any help?
It sounds like your problem is the air mixing doors in the air box, not a sensor. They could be sticking, you may have a vacuum leak, or maybe your climate control module (where the temp. and fan speed controls are) is bad.
