Check your thermostat. If it’s set too low, your heating system won’t be able to heat up the cabin enough to keep you comfortable.
You may also want to check that there’s no air leaking into the cabin from underneath or around doors or windows if there is, this will prevent your heater from being able to do its job effectively.
The coolant level might be low or there could be a leak in the system somewhere. If you have a leak, you may need to replace a hose or other part of the system.
If the coolant is full and there are no leaks, the heater core could be plugged up with debris from an old water pump failure.
It’s possible that your car’s heater core has been damaged by rust and needs replacement.
If none of these situations apply to your situation, we recommend taking your car in to a mechanic as soon as possible so they can diagnose your specific problem
What causes the car heater to not get hot enough?
Make sure that the temperature on your dashboard is set to hot and that the car has been driven enough to reach normal operating temperature.
While it is not uncommon for the heater to work slowly at first, it should get hotter as the engine heats up.
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?
Turn on the car and let it run for a few minutes. Allow your engine to warm up so that you can tell whether or not your issue is related to the temperature of your vehicle or if there’s something else going on.
These could indicate problems with other components like belts, hoses, etcetera.

Why is this happening?
Your thermostat might need to be replaced. This is a common problem for older cars and one that can be easily remedied by an experienced mechanic.
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.
If your heat pump is not working, you may be able to fix it by checking the thermostat and replacing any broken parts.
Conclusion
This can be caused by a number of different things, but the first thing to check is your thermostat.
If your thermostat is stuck open or closed, this will prevent your engine from getting hot and therefore won’t be able to produce enough heat to warm up the cabin.
If this is the case, you’ll want to replace your thermostat with one that has been tested by a professional.
