If your heater does not work on your 94 Mazda Protege, check the thermostat. You can also check the heater fuse to ensure it has not blown.
You could have a problem with your thermostat in the car.
You might need a new thermostat or heater core.
It's possible that your heater core is plugged up. It can also be a bad thermostat.
A heater thermostat controls the temperature of water in a heating system. A heater thermostat can be purchased from companies such as Hygiene Supplies Direct and Alibaba.
yes if it stuck open.
Could be: Low coolant in the radiator - or - thermostat stuck open - or - heater core plugged.
It's because the thermostat is stuck open.
Low coolant? Bad thermostat? Heater core plugged,restricted or airbound? Heater control cable or valve not working?
Running a vehicle without a thermostat will cause it to take longer to warm up and your interior heater may not blow hot air.
Technically, yes they can run without a thermostat. (not without coolant, just no thermostat) However, several things will happen. First, the engine will be cold all the time which will make it use more gas. Also, your heater will not work. Another thing is that your engine will not produce as much power because it's cold. etc. note: if this is being done to fix a problem like overheating, it will only work if the problem is caused by a faulty thermostat.
Most common things are Thermostat or a bad heater core but could also be something blocking the door down by the heater core. I changed my Thermostat and Heater control Valve to find out a pencil fell in the defroster and prevented the door from closing. Hope this helps.
Check coolant level .Then thermostat . Then hearter core
Yes, the vehicle should still work without a thermostat. Howeve, the enigine will take much longer to reach its normal oprating temperature.

If you are not getting heated air blowing from the heater core and your engine coolant temperature gauge is showing LOW or below normal , ( then YES , IT'S POSSIBLE that your engine cooling thermostat is sticking open )
the heater core could be pluged or the heater control valve is stuck closed
Low coolant? Heater core airbound, restricted, or plugged? Bad thermostat? Water pump not circulating coolant?
yes you can drive it without thermostat the only thing is before winter you will want to replace it or your heater will not work ( also the engine will take longer to warm up , the gas mileage will suffer , the check engine light will probably come on etc . )
Someone turned up the thermostat, or the thermostat has failed. The thermostat tells the heater what temp to keep the water at.
