Heater problem
2000 Buick Century Front Wheel Drive Automatic

the heater will blow on high when the brakes are applied but on low any other time. This is a new control.
is there anything I can do to fix this?

This is interesting. I can't think how the two systems are tied together. Have you checked the blower motor resister? Also, try running a seperate ground from the motor to the body. See if that makes a change.

Let me know.

Step 1 - A heater cannot operate unless the engine is full of coolant/antifreeze. If coolant level is low check the system for leaks.
