no indeed it doesnt have anything to do with it. you see the ac heater has diffrent conections in where the theremostat has nothing to do with if u were talking with temperature changes maybe it would.
Check the thermostat.
First place to look is the thermostat
The AC switch operates the AC compressor and should have no bearing on your heater function. If your heater is not working properly, you may have a weak thermostat.
That or the thermostat.
It matters if it has ac or not. If it is a non ac vehicle, the hoses and coolant flow from the fitting close to the thermostat housing to the lower heater core tube, then out the upper heater core tube to the fitting on the water pump. If it has ac, the hose from the upper heater core tube connects to the fitting on the radiator.
To troubleshoot issues with your AC and heater system, check the thermostat settings, replace air filters, inspect the circuit breaker, clean the condenser unit, and schedule regular maintenance with a professional technician.
The heater core is usually your last resort. So now start from the end to the beginning, core, thermostat, flush, hose, fluids. Follow the trail and your bound to find your answer.
the thermostat used to control the heater and after we select the four pole switch to some number the thermostat start connect the power to the heater at the same time the heater start to heat and when we select the switch to zero position the heater not work
If both the AC and heater are coming on at the same time, it could be due to a malfunction in the thermostat or HVAC system. This issue can occur if the thermostat is set to "auto" mode, causing it to activate both the heating and cooling systems simultaneously. It's best to have a professional HVAC technician inspect and repair the system to ensure it is functioning properly.
An AC water heater can be converted to operate on DC current but the cost will be large. In the electrical trade anything can be done if enough money is spent to get the results that are requested.
The purpose of the thermostat wires outside the AC unit is to connect the thermostat inside the building to the AC unit outside, allowing the thermostat to communicate with the AC unit and control its operation based on the desired temperature settings.
can a faluty thermostat affect your central ac working?
