Expert Car Heater Repair in Warren & Clinton Township
At Kozak’s Collision and Auto Repair, we know how vital a working heater is during Michigan winters. Whether you need routine auto heat service, a heater core flush, or full car heater service, our experienced technicians deliver the reliable results you need.
Common Heater Problems
A failing heater can be caused by several factors. Low coolant levels, a malfunctioning thermostat, or a clogged heater core can all prevent the system from producing heat. In some cases, a faulty blower motor may be the reason warm air isn’t reaching the cabin. Identifying the exact cause is key to restoring proper function.
Diagnosing Heating System Issues
When a heater stops working, it’s often a sign of a bigger problem within the cooling system. Since the engine’s heat is used to warm the cabin, any issue with coolant circulation can impact both the heater and the engine’s temperature control. Our technicians conduct thorough inspections, checking for leaks, thermostat failures, or blockages in the heater core to determine what needs to be fixed.
Heater Core and Blower Motor Repairs
The heater core is responsible for transferring engine heat into the cabin. If it becomes clogged or damaged, your heater may blow cold air or develop a musty smell from trapped moisture. Similarly, if the blower motor stops working, air won’t circulate properly through the vents. We provide expert repairs and replacements to restore full heating function to your vehicle.
Preventative Maintenance for Reliable Heat
Regular maintenance can help prevent heater failures before winter arrives. Flushing the coolant, checking the thermostat, and inspecting hoses for leaks are all part of ensuring your heating system stays in top shape. Addressing minor issues early can prevent costly repairs down the road and keep your car comfortable in cold weather.
