Common heating problems we diagnose and repair include:

• Leaks from the heater core

From compact sedans to SUVs and hybrids, Toy Doctor Auto Repair has the tools and experience to fix it all.

How Your Car Heater Works

Your vehicle’s heater uses the heat generated by the engine to warm the air inside your cabin. Here’s a simplified breakdown of how the system works:

1. Coolant absorbs heat from the engine.

2. The heated coolant flows through the heater core.

3. A fan (blower motor) pushes air over the heater core.

4. Warm air is distributed through the cabin vents.

If any component in this process fails, your cabin may stay cold, or worse—your engine may overheat. That’s why prompt car heater service is so important.

Comprehensive Auto Heat Services We Provide

When you bring your vehicle to Toy Doctor for heater repair, we perform a full inspection and diagnosis to identify the issue and recommend the best solution. Our heating system services include:

Heater Core Diagnosis & Replacement

A clogged or leaking heater core can prevent warm air from reaching your cabin. We’ll inspect the core and replace it if necessary.

Thermostat Testing & Replacement

If your thermostat is stuck open or closed, your engine may not reach the optimal temperature, affecting heater performance. We’ll test and replace it if needed.

Coolant System Inspection

The heater depends on your engine’s coolant system. We check coolant levels, look for leaks, and flush old coolant when necessary.

Blower Motor Repairs

If your fan isn’t working or airflow is weak, we’ll inspect the blower motor and resistor for proper function.

HVAC Control Diagnosis

If you can’t adjust the temperature or airflow direction, the issue may lie in the controls or blend door actuators. We’ll repair or replace faulty components.

Electrical & Fuse Checks

Electrical issues or blown fuses can disrupt your heating system. We check all electrical connections and restore functionality.

Signs You Need Car Heater Service
