The thermostat regulates the temperature of your car’s engine and prevents it from overheating.

If your heater isn’t getting hot enough, the thermostat may be stuck in a position that doesn’t allow it to open and close properly.

This can cause a buildup of heat in your engine, which will lead to overheating.

The fan may be set too low and unable to heat up the cabin quickly enough when it is turned off completely or set to low speed only.

You can also adjust this setting manually by turning the knob on top of your dashboard until it reaches a higher setting.

Turn off other electrical components such as lights or air conditioning if possible so that more energy will be directed toward heating up your car instead of cooling down any parts that may cause excess heat such as windows or seats.

How to troubleshoot the heater?

Your blower motor could be going out, which means it won’t circulate air throughout the car as efficiently as it should.

A replacement blower motor will fix this problem, but it’s important to note that these motors tend to fail gradually over time rather than suddenly, so you may notice other symptoms of trouble first.

There may be something blocking the heater vents in your vehicle’s cabin, such as a piece of clothing or debris from the road if you recently drove through some mud or gravel.

How can you fix it yourself?

If your air conditioner is not working, you may be able to fix it yourself by checking the fuses or replacing a part in the fuse box or wiring harness.
