Heating Problems

[911stu]

Hi, can anyone help me. I have an 89 e230 that has no hot air on any of the passenger side vents including the screen. All of the drivers side heating is fine.
Any advice will be much appreciated. Cheers

Hello and welcome .

Your fault will be the duo valve and one side has stuck or faulty.

Thanks for that. I have also been told that by someone else. Do you know if this can be taken off and cleaned up or is it replace only? I have also been told that if they go it stays hot. Any idea if thats true?

Yes I was aware of the usually hot bit when they fail, take the top on and see if it is stuck, its one of the only easy bits that you can do
