Heater Repair in Redding, CA

Heater Core, Blower Motor, Thermostat & Climate Control Diagnostics

When Redding winters hit and your car heater blows cold air, it's miserable — and it might point to a more serious cooling system problem. NorCal Precision Auto & Electric Repair diagnoses and repairs all automotive heating system issues, from a stuck thermostat to a leaking heater core.

Understanding the System

How Your Car's Heating System Works

Your car's heater uses waste heat from the engine. Hot coolant circulates through the heater core (a small radiator inside the dash), and the blower motor pushes cabin air across it to generate warm air. When any component fails, you lose heat.

1
Heater Core
The small heat exchanger behind the dashboard that warms cabin air
2
Blower Motor
The fan that forces air across the heater core and through the vents
3
Thermostat
Must open and close correctly for the engine to reach heating temperature
4
Blend Door Actuator
Controls the mix of hot and cold air at the vent
5
Coolant Level
Low coolant prevents the heater core from receiving hot fluid
6
Heater Control Valve
Regulates coolant flow into the heater core on some vehicles
