I've 528e bmw 1988 model. Have problem with heater, it does not work. It was working couple of months ago untill I replace the throttle body due to leak from the throttle body cover. I had already check and replace the heater valve with used one. Need the heater to be working since winter is just around the corner. How do you know if the heater valve is working good? Any advice ....
