Can any conclusions be reached yet?
disconnect the monovalve, and went for a...drive The air started blowing TOASTY WARM...at 50 mph the dash air lost its heat and cooled to ambient
Only a bad monovalve can do this.
I swapped out the ACC push button module with a good used... reconnected the monovalve and went for another spin. Not only did the air remain warm, but it modulated in response to the ACC temperature wheel.
Any _other_ problems are/were due to the PBU. It is entirely common to have more than one problem in this system. The failing monovalve, before it's totally defunct, may choose to work fairly well at times. -- Jim _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com All posts are the result of individual contributors and as such, those individuals are responsible for the content of the post.
