THERMOSTAT

Friend it seems that we speak another hahaha language, there is no sensor that circulates the water, the pump is the one that circulates it, there is no sensor for that, or do you mean that the elctroventillator is not activated?

If you eliminated the heating pass and instead you placed plugs there is the friendly detail ..

How did you check that water does not circulate? You have a test, take out the valve or spring thermostat, close everything again water and strangle with your hand the hose that enters the radiator to 150 2000 rpm (hot water) and feels if there really is no water exchange, if you do that you do not feel the passage of water you have to check the water pump again, there are cases that seem all good but it turns out that the pump can be released

All the people were made and nothing, the vehicle is a BMW year 1997, it is totally electronic it is full of sensors has four computers the vehicle is working ,,,, just wants to circulate the water, the pump is good the heating does not work and has no plug

It is difficult for a duct to cover, look, you have a sensual test, take out the thermostat as Bata says, and walk the upper hose of the radiator and the lower one made water through the hose and it will reveal fall through the below, if this works like this but when there is no symboling there is no symbol then the compression of the compression camera is upholstered, I have seen it once in my life.
