Common Heating and Cooling System Issues in Winter and How to Fix Them

When winter hits in Lakeville, MN, your car’s heating and cooling system works overtime. It keeps your engine at the right temperature and keeps you warm and comfortable behind the wheel. Cold weather can expose hidden problems, which is why heating and cooling issues are more common this time of year. At GVT Lakeville South Repair in Lakeville, MN, we help drivers handle these problems before they turn into breakdowns.

Low or Leaking Coolant

One of the most common winter issues is low coolant. Cold temperatures can make small leaks in hoses or the radiator more noticeable. Low coolant can lead to poor heater performance and even engine overheating.

The fix starts with a pressure test to find leaks, followed by repairing damaged hoses or components and refilling the system with the correct coolant mixture.

Heater Not Blowing Warm Air

If your heater is running but only blowing cold or lukewarm air, several things could be to blame. Low coolant, a stuck thermostat, or a clogged heater core can all prevent heat from reaching the cabin.

A professional inspection helps identify the cause and restore proper heat so you stay comfortable and safe during winter driving.

Frozen or Stuck Thermostat

Thermostats regulate engine temperature. In winter, a thermostat that sticks open can prevent the engine from warming up properly. This leads to weak heat and poor fuel efficiency.
Replacing a faulty thermostat helps the engine reach and maintain the correct operating temperature.

Overheating Despite Cold Weather

It might seem odd, but engines can still overheat in winter. Blocked radiators, malfunctioning cooling fans, or coolant circulation problems can cause overheating even in freezing temperatures.

Addressing these issues early helps prevent serious engine damage.

Weak Defrost and Foggy Windows

Your heating system plays a key role in keeping your windshield clear. If the defroster isn’t working well, it could be due to airflow issues, heater core problems, or a failing blower motor. Fixing these issues improves visibility and safety.

Prevent Winter Heating and Cooling Problems With Maintenance

Routine maintenance is the best way to avoid winter heating and cooling issues. Regular coolant checks, system inspections, and timely repairs help keep everything running smoothly when temperatures drop.
