At the simplest level, there are two main reasons why the heater is not working. If it’s not coming on at all, it’s usually either the blower motor or some other wiring issue. If the heat is blowing, but blowing cold, it has something to do with the coolant getting to the heater core, or the heater core itself.
Q. Why is my heater not getting hot in my car?
A heater can stop working for a number of reasons, including: A low antifreeze/water level in the radiator due to a leak in the cooling system. A bad thermostat that isn’t allowing the engine to properly warm up. A blower fan that isn’t working properly.

Q. Does the thermostat affect the heater?
A malfunctioning thermostat may cause your heating system to short cycle. Short cycling is the term professionals use to describe what happens when your heating or air conditioning system shuts off too soon, before the heating cycle is complete, and runs frequently. Usually, a broken thermostat will simply be replaced.
Q. How do you drain the coolant on a mk7 Golf?
You have to pull a hose off at the bottom of the radiator, and then fill from the overflow bottle. You only get a portion of the coolant out, though, so you need to do it a few times and drive around. I think it’s like 40% on each drain and fill, going off of memory.
Q. How do I know if my central heating thermostat is broken?
The most common signs of a broken thermostat are:
- Thermostat display is off or is non-responsive.
- Turning on the heat or AC does nothing.
- The heat or AC will come on, but either stays on nonstop or cuts out before the temperature setting is reached.
Q. Can you replace a thermostat with any thermostat?
Replacing a Thermostat in Your Home. Purchase a replacement thermostat that will work with your system. Most replacement thermostats are compatible with all common systems. However, if your system is unique, finding a replacement thermostat may be difficult.
