Car Heater Repair in Lewisville & Irving, TX
When the weather turns cold in North Texas, a working heater isn’t just a luxury—it’s a necessity. Few things are more frustrating than stepping into your car on a frosty morning only to be greeted by cold air blasting from the vents. If you’re looking for reliable car heater repair in Lewisville & Irving, TX, Lakeshore Automotive is the trusted shop. Our team has years of experience diagnosing and fixing heater problems, making sure your drives stay safe and comfortable.
The Difference With Our Heater Services
Car heaters are often overlooked until they stop working, but the reality is they’re connected to several critical systems in your vehicle. At Lakeshore Automotive, we approach every repair with a full-system mindset. Instead of patching symptoms, we dig into the details—checking coolant flow, blower function, thermostats, and electrical controls. That difference in approach means long-term results instead of temporary fixes.
How Your Car’s Heating System Works
Understanding how your heater functions can help you spot issues earlier. Here’s a simple breakdown:
- Coolant circulation: The engine warms the coolant as it runs.
- Heater core: That hot coolant flows through a small radiator-like part located inside your dash.
- Blower motor: Air passes over the heater core and absorbs the heat.
- Cabin vents: Warmed air is delivered to the cabin, keeping you comfortable and helping to defrost windows.
If any step in this chain is disrupted—by a clogged core, stuck thermostat, weak blower, or electrical fault—your heater won’t deliver.
Common Problems Requiring Car Heater Service
Drivers in Lewisville and Irving often experience the same recurring heater problems:
- Cold air instead of heat – Often caused by low coolant or thermostat issues.
- Foggy windows – A weak heater or blower prevents defrosters from clearing the glass.
- Coolant leaks – A sign of heater core or hose problems.
- Burning smells – Could indicate electrical issues or debris in the vents.
- Weak airflow – Typically linked to blower motor or resistor problems.
Catching these signs early makes heater repairs quicker and less expensive.
Our Complete Auto Heat Services
At Lakeshore Automotive, we provide a full range of services to restore comfort and reliability.
Heater Core Repair & Replacement
When the heater core gets clogged or leaks, the airflow temperature drops quickly. We repair or replace the core to restore heat.
Thermostat Replacement
If the thermostat sticks open or closed, coolant won’t flow correctly. Replacing it ensures your heater—and engine—stay in the right temperature range.
Blower Motor Repairs
The blower motor is responsible for pushing air into the cabin. If it fails, airflow weakens or stops completely. Our team repairs or replaces motors, resistors, and wiring.
Coolant System Service
Because the heater relies on the same coolant as the engine, leaks or dirty coolant will affect the heat. We flush and refill the system, check hoses, and repair leaks.
Electrical Component Repairs
Switches, relays, and wiring also affect heater performance. We inspect and repair electrical connections so your controls respond the way they should.
DIY Troubleshooting vs. Professional Repair
Some drivers wonder if they can fix heater issues themselves. While you can do a few quick checks at home, most problems require professional tools and knowledge.
What you can do:
- Check coolant levels and add more if low.
- Listen for blower fan noises.
- Turn on the defroster to see if the airflow works.

How North Texas Weather Affects Heaters
Unlike northern states, Lewisville and Irving don’t see long winters, but the sudden swings in temperature can be hard on heating systems. You may go months without using your heater, only to discover it doesn’t work on the first cold morning. Hot summers also take their toll on coolant and seals, which affects heater performance later in the year. That’s why regular inspections and preventive care are so important in this region.
Everyday Benefits of a Working Car Heater
Fixing your heater is about more than comfort. Here’s what you gain from keeping the system in top shape:
- Safe driving: A working defroster keeps your windshield clear in damp or cold weather.
- Comfortable rides: Your commute or errands are far easier when your cabin is warm.
- Engine health: A healthy coolant system supports both the heater and the engine.
- Peace of mind: You won’t get caught by surprise when temps suddenly drop.
Tips to Prevent Heater Problems
You can help avoid heater failures with a few simple habits:
- Have the coolant flushed according to manufacturer guidelines.
- Run the heater briefly even in summer to keep parts lubricated.
- Pay attention to coolant leaks and fix them promptly.
- Don’t ignore unusual smells or sounds coming from vents.
- Schedule seasonal inspections before winter arrives.

FAQs About0 Car Heater Repair in Lewisville & Irving, TX
Why does my car blow cold air when the heater is on?
Low coolant, a thermostat issue, or a clogged heater core often cause this.
Can heater problems affect my engine?
Yes. Since the heater uses engine coolant, a leak or blockage can create overheating problems.
What’s the most common heater issue in Texas?
Low coolant and thermostat failures are very common, especially after hot summers.
Do you work on both import and domestic cars?
Yes, our technicians service a wide range of makes and models.
Is it normal for my heater to smell when I turn it on?
Not always. It could be dust burning off, but if the smell is sweet or chemical-like, it may be a coolant leak.
How often should my heater system be checked?
At least once a year, ideally before winter, to make sure it’s ready when you need it.
Can I drive without fixing a broken heater?
Technically, yes, but it reduces comfort and visibility since defrosters won’t work properly.
