I will accept after my problem gets solved. If this fixes my problem I will accept but not untill then. Thank you if you dont want to provide diagrams without accept let me know so I can get help with somone else. Thank you for your help.
Here is the answer to your question! You need a heater control valve assembly, period. Just as the expert already answered. Here is your diagram. $246.42 from the BMW dealer. As far as your second question, with the first one answered, you can't fix it, you can only replace the component. Or you could replace the heater core for $3000.00, but that won't fix it! I was very reluctant to give you information after a look at your history. I am giving you the benefit of the doubt. Now, we shall see!
Yes, you can request me. I will be happy to assist you in the future. Thank you.
