The valve is located inside the dash to the rigth of the glove box,it has 7 or 8 color coded vacuum lines on it and is pretty easy to replace.
Mike: This is exactly my problem,do you I have to remove the dashboard or just the glove box,Do you have the part no for this.Could you elaborate on how to remove the vacuum switch .I'm sure you will help alot or 190e owners because many of them encounter this problem.Thanks
